General safety instructions

The device is built according to current state-of-the-art technology and applicable regulations. The devicecomplies with the EU machinery directive, harmonised standards, European standards or the applicable na-tional standards. This is confirmed with a manufacturers declaration.Relevant accident prevention regulations, generally accepted safety-related rules, EU guidelines, other ap-plicable standards and country-specific regulations are also applicable.Because linear units can be used in such a wide range of applications, the ultimate responsibility and liabi-lity for appropriate use lies with the end user.This device creates an unavoidable residual risk for personal injury and material damage. For this reason, everyindividual who works on this device associated with the transport, assembly, operating, maintenance and re-pair of the device, must receive instruction and understand the potential dangers. The operating instructionsmust be understood and observed.In addition, actuating equipment poses a risk of injury due to rotating or otherwise moving components. Dueto moving carriages, operational linear axes particularly pose an increased crushing hazard, especially inconnection with end position dampers and limit switches. The user must make these residual risks known withsigns or written codes of conduct. Alternately, the user can eliminate or exclude these residual risks to thegreatest extent possible by employing appropriate constructive measures.Linear unit commissioning is prohibited until it can be established that the machine or system in which it ismounted conforms to EU machinery directives, harmonised standards, European standards or applicablenational standards.

Intended use

SNR linear axes and SNR linear tables are fundamentally designated for linear movement as occurs duringpositioning, synchronisation, transport, palletising, loading, unloading, clamping, tightening, testing, measu-ring, handling and manipulating components or tools. Type-specific load data from the relevant SNR catalo-gue documentation and/or SNR supplementary technical calculations must be observed. Furthermore, anoperating temperature between 10C to +40C must be adhered to.

Alternative or excessive use is considered improper use. The manufacturer assumes no liability for resultingdamages. The user bears sole responsibility for all risks.

The linear axis may only be operated and serviced by individuals familiar with the axis and who have beeninstructed in the dangers.

Transport and storage

Transport and storage provisions

SNR linear axes are high-precision devices. Heavy impact can damage linear axis mechanisms and impair

performance. To avoid damage during transport and storage, the following should be observed:

Protection against vigorous vibration and/or impact, aggressive media, moisture and soiling

Packaging in a suitably large box or crate with secured and padded to ensure against movement.

Special care should be observed to protecting the corners and exposed elements such as switches

Assembly and commissioning

Linear axes assembly and mounting

SNR linear axes from the AXC and AXDL series can be mounted on level surfaces or other linear axes from

the SNR catalogue using T-nuts or fixing strips. The number of mounting points must be verified for the ap-

plication. It must be ensured that any resulting deflection of the profile or system neither impedes perfor-

mance and/or required accuracy.

The fixing strips are hooked to the linear axis profile sides; their special shape allows for simple mounting by

bolting from above (fig. 1 and 2). They may be freely positioned along the entire profile length.

Alternately, all linear axes may be mounted via pivoting sliding blocks that may also be freely positioned along

the entire length (fig. 3).

Fig. 1

Fig 2 Fig. 3

6

Two mounting options are available for AXLT linear tables: either through direct bolting from above or with pi-voting T-nuts from the underside of the table which may be freely positioned along the entire length (fig. 4).

AXS series linear axes can also be affixed using T-nuts as well as with (custom made) adapter plates if re-quired to level surfaces or other SNR linear axes.

The number of fastening points should be verified in terms of application for all mounting types. It must beensured that any resulting deflection of the profile or system neither impedes performance and/or requiredaccuracy.

Notice for linear axis commissioning

Linear axes can generate fast movement with a large degree of force. Carriage fittings can lead to bodily in-jury or material damage upon collision. Commissioning should thus be performed with the utmost caution.

Furthermore, it should be ensured upon commissioning that the permissible loads are not exceeded and thecarriage fittings are securely fastened. It should also be ensured that the maximum possible travel is not ex-ceeded. If travel is limited with limit switches, they should be previously tested in terms of performance andcorrect positioning.

The manufacturer is not liable for damages resulting from non-observance of these commissioning instruc-tions. The user bears sole responsibility for all risks.

Maintenance and lubrication

General maintenance and care instructionsDrive systems

The toothed belt does not generally require maintenance work and will be set to the correct tension during

manufacture. Retightening is not necessary during service life with intended use. For servicing the ball screw

drive, please observe the information in the maintenance intervals and lubricant quantities section.

Please note:

In a system that utilises two axes connected with a shaft the toothed belts in both axes

should be replaced.

Guiding systems

Because the rollers in the roller guides are equipped with lifelong lubrication, they do not need to be ser-

viced. Guiding system prestressing is performed during manufacture. Readjustment is unnecessary during

service life with intended use. Roller guide shafts are supplied with oil via lubricating felt located in the car-

riage. Please observe the information in the maintenance intervals and lubricant quantities section.

For ball rail system maintenance, please observe the information in the maintenance intervals and lubricant

quantities section.

To ensure long term performance of the linear axis, it is necessary to perform periodic inspects for external

damage and contamination. In harsh ambient conditions with intensified contamination, the inspection pe-

riod should be adjusted accordingly to perform necessary cleaning and relubrication. Following longer pe-

riods of linear axis use, it may be necessary to replace brush scrapers and/or sealing strip in the course of

cleaning. Please observe the following mounting instructions.

Brush scraper replacement AXC seriesTo take out the brush scraper and replace it with a new one (fig. 10), loosen and remove the screws. Terms

for spare parts orders can be found in the accompanying assembly drawing.

Sealing strip replacement AXC series

First loosen and remove the screws (a) in the carriage to remove the slide plate (b). The belt clamping on theaxis ends can then be loosened. With toothed-belt axes, the sealing strip is clamped by the end positiondamper (c) and loosened by removing the cap screw (d) (fig. 12). Ball screw drive linear axes feature a beltclamping through a sheet (e) that can be removed by unscrewing the retaining screws (f) (fig. 11). The old sea-ling strip (g) can then be removed and replaced with a new one.

Please always indicate the linear axis serial number when ordering a replacement sealing strip so itcan be cut to the exact length of the respective profile to achieve an optimum sealing.

Prior to mounting the new masking belt, it must be ensured that the pressure roller in the slide plate and theguide rollers in the carriage section can be slightly turned on the steel pins. The pins should be cleaned orreplaced, if necessary (fig. 13).

The sealing strip has a trapezoidal cross section. When applying the new sealing strip, it must be ensured thatthe broadest surface is on the bottom. Applying gentle pressure by hand or with a smooth object free ofsharp edges, latch the belt into place in the intended slot so that it is flush with the upper profile edge. Moun-ting can also be performed in the reverse of disassembly order.

Masking belt replacement AXDL series

First loosen and remove the belt deflection (b) together with the lubricating nipple (f) and the disc (e). The at-

tachment rail (d) can then be removed by unscrewing the retaining screws (c). The old masking belt (a) can

now be removed and replaced with a new one.

Mounting can also be performed in the reverse of disassembly order.

Important note: The new sealing strip should be tightened in a way that it does not drag on the table (not sure

what this means)!!!. This can be checked with inspection bore holes in the slot bottom (sealed with plastic

plugs).

Maintenance intervals and lubricant quantities

Linear ball rail systemWith various test conditions, it was established that the calculated life span can be achieved with initial grea-sing.

Because the lubricant manufacturer does not guarantee a general service life for its products, we recom-mend a relubrication interval of 10,000 km of linear travel or once per year.

Longer relubrication intervals are possible after consulting the lubricant manufacturer for a defined applica-tion, if necessary. A petroleum-based lithium soap roller bearing lubricant should be used for relubrication;otherwise, the compatibility must be reviewed.Lubricants with a solid lubricant percentage (e.g. graphite or MoS2) may not be used.

Because relubrication interval depends on several factors, e.g. degree of soiling, operational temperature,load, etc., the information stated here should only serve as a guideline.

Ball screw driveStandard lubrication requirements for rolling bearings apply for ball screw drives. Lubrication loss is greaterthan with conventional rolling bearings due to axial movement between the shaft and the screw nut. Grease-lubricated ball screw drives have the advantage of only needing relubrication after long travel, meaning thata relubrication device can be omitted in many cases. The lubrication amount should be measured to ensurethat hollow spaces are approximately halfway filled. All high-quality roller bearing lubricants are suitable foruse. Please observe lubricant manufacturer guidelines!Lubricants with a solid lubricant percentage (e.g. graphite or MoS2) may not be used.If you wish to achieve as long of a relubrication interval as possible, greases pursuant to DIN 51825 K2K andpursuant to DIN 51818 for higher loads KP2K of NLGI class 2 should be favoured

This means that the quan-tities listed above may only be applied into the respective lubricating nipple on one side of the axis perlubrication interval.

Relubrication option for linear axes with toothed belt drive. Lubrication point F for axis type AXC120 with ballscrew drive and roller guide.

The given factor is to be applied as follows:AXC series: For incline mounting position and initial relubrication overhead mounting.AXDL series: For overhead and incline mounting position for initial relubrication.

We recommend a relubrication interval of 5,000 km or once per year.Oil to use: ISO- VG 460.

Rack and pinion lubrication

The toothed rack drive is optimally supplied with lubricant with a permanent lubrication system (fig. 17) in con-junction with a felt cog. The system is filled with SNR LUB EP lubricating grease and may only be set to themaximum emptying time.

When operating the switch, select the maximum emptying time of one year. This closes the respective swit-ching circuit and permits an electric current with respective intensity according to the desired lubrication flowrate. The electrochemical cell generates a neutral gas primarily composed of nitrogen (90%). This gas fills thechamber and presses the pistons that, in turn, press out the lubricant in the container with help from the fle-xible partition wall.

Service life is set to one year by default.

Power switch to on (see fig. 18): the indicatorlight flashes to indicate that the device is ope-rational.

When ordering the new permanent lubricationsystem, please indicate the order code Grais-seur SNR.EP.
