Basic Dynamic Load Rating (C)
This term is arrived at based on an evaluation of a
number of identical linear systems individually run
in the same conditions, if 90% of them can run with
the load (with a constant value in a constant
direction) for adistance of 50 km without damage
caused by rolling fatigue. This is the basis of the
rating.
Allowable Static Moment (M)
This term defines the allowable limit value of static
moment load,with reference to the amount of
permanent deformation similar to that used for
evaluation of basic rated load (Co).
Static Safety Factor (fs)
This factor is used based on the application
condition as shown in Table 1.
Rating Life of the Linear System
As long as the linear system reciprocates while
being loaded,continuous stress acts on the linear
system to cause flaking on the rolling bobies and
planes because of material fatigue. The travelling
distance of linear system until the fist flaking
occurs is called the life of the systems of the same
dimensions, structure,material,heat treatment and
processing method, when used in the same condi-
tions,This variation is brought about from the essential
variations in the material fatigue itself. The rating life
defined bellow is used as an index for the life expec-
tancy of the linear system.
Rating Life (L)
Rating life is the total travelling distance that 90%
of a group of systems of the same size can reach
without causing any flaking when they operate under
the same conditions.
The rating life can be obtained from the following
equation with the basic dynamic load rating and the
load on the linear system:
L:rating life (km) C:Basic dynamic load rating (N)
P:Load (N)

Rating Life
Basic Static Load Rating (Co)This term defines a static load such that, at the contacting position where the maximurn stress is exercised, the sum of the permanent deformation of the rolling elements and that of the rolling plane is0.0001 time of the diameter of the rolling elements.

When elastic deformation should be considered with respect to pinch load 2to4
When the equipment is subject to vibration and impacts 3to5
Consideration and influence of vibration impact loads and distribution of load should be taken into account when designing a linear motion system . it is difficult to calculate the actual load . The rating life is also affected by the operating temperature. In these conditions, the expression (1) is arranged as follows:
L:Rating life (km) fh:Hardness factor (See Fig.1)
C:Basic dynamic load rating (N)
fT:Temperatuer coefficient (See Fig.2) P:Load (N)
fC:Contact coefficient (See Table 2)

The rating life in hours can be calculated by obtaining the travelling distance per unit time. The rating life in hours can be obtained from the following expression when the stroke length and the number of strokes are constant:

TECHNICAL INFORMATION
Hardness Factor (fH)
Temperature Coefficient (fT)
Contact Coeffcient (fc)
Load Coefficient (fw)
The shaft must be sufficiently hardened when a linear
bushing is used. lf not properly hardened, permissible
load is lowered and the life of the bushing will be
shortened.
If the temperature of the linear system exceeds 100
hardness of the linear system and the shaft lowers to
decrease the permissible load compared to that of the
linear system used at room temperature. As a result,
the abnormal temperature rise shortens the rating life.
Generally two or more linear bushings are used on
one shaft. Thus, the load on each linear sysem differs
depending on each processing accuracy. Because the
linear bushings are not loaded equally, the number
of linear bushings per shaft changes the permissible
load of the system.
When calculating the load on the linear system, it is
necessary to accurately obtain object weight, inertial
force based on motion speed, moment load, and each
transition as time passes. However, it is difficult to
calculate those valuse accurately because reciprocating
motion involves the repetition of start and stop as well
as vibration and impact. A more practical approach is
to obtain the load coefficient by taking the actual
operatingconditions into account.

The static frictional resistance of the
linear system is so low as to be only slightly
different from the kinetic frictional resistance,
enabling smooth linear movement from low to
high speeds. in general, the frictional resistance
is expressed by the following equation.
The frictional resistance of each linear KOLMB
system depends on the model, load weight,
speed, and lubricant. The sealing resistance
depends on the lip interference and lubricant,
regardless of the load.
The ambient working temperature range for each
KOLMB linear system depends on the model.
Consult on use outide the recommended KOLMB
temperature range.
Temperature conversion equation
C=
F=
Using linear systems without lubrication increases KOLMB
the abrasion of the rolling elements, shortening the life
span, The linear systems therefore require appro-KOLMB
priate lubrication. For lubrication recommends KOLMB
turbine oil conforming to ISO Standards G32 to G68 or
lithium base soap grease NO.2. Some linear KOLMB
systems are sealed to block dust out and seal lubrication.
If used in a harsh or corrosive environment, however,
apply a protective cover to the part involving linear motion.

TECHNICAL INFORMATION
Structure and Features
The linear bushing is produced from a solid
steelouter cylinder and incorporates an industrial stre-
ngth resin retainer.
The standard type of linear bushing can be
loaded from any direction. Precision control is Possible
using only the shaft supporter, and the mounting
surface can be machined easily.
linear bushings of each type are completely
interchangeable because of their standardized
dimensions and strict precision control. Replacement
because of wear or damage is therefore easy and
accurate.

Relation between ballcircuits and load ratingThe linear bushing includes ball circuits that are spaced equally and circumferentially. The load rating varies according to the loaded position on the circumference.
KOLMB The value in the dimension table indicates the load rating when the load is placed on top of one ball circuit. if the linear bushing is used with two ball circuits loaded uniformly, the load rating will be greater, The following table shows the values by the number of ball circuits in such cases:

Clearance and Fit
When a standard-type linear bushing is used
with a shaft, inadequate clearance, adjustment may
cause early bush failure and / or poor, rough traveling.
The clearance adjustable linear bush and open linear
bush can be clearance adjusted when assembled in
the housing which can control the outside cylinder
diameter. However, too much clearance adjustment
increases the deformation of
KOLMB The outside cylinder cylinder, to affect its precision
and life. therefore, the appropriate clearance between
the bush and shaft, and clearance between the bush
and housing are required according to the application.
Table 2 shows recommended fit of the bush:
Table 2
Model
Division Shaft Housing
Normal fit Transitional loose fit Tight fit
LM High class g6 h6 H7 J7
LMB
LME High class h6 j6 H7 J7
Note: The clearance may be zero or negative. Please attention the movement.
Shaft and HousingTo optimize performance of the linear bushing high precision of the shaft and housing is required.KOLMB
The rolling balls in the linear bushing are
in point contact with the shaft surface Therefore,
the shaft dimensions, tolerance, surface finish,
and hardness greatly affect the traveling
performance of the bush. The shaft should be
manufactured with due attention to the following
points:
1.since the surface finish critically affects smooth
rolling of balls, grind the shaft at 1.5 S or better
2.Thebest hardness of the shaft is HRC 60 to 64.
Hardness less than HRC 60 decreases the life
considerably, and hence reduces the permissible
load. On the other hand, hardness over HRC 64
accelerates ball weer.
KOLMB 3.The shaft diameter for the clearance adjustable
linear bush and open linear bush should as much
as possible be of the lower value of the inscribed
circle diameter in the specification table. Do not
set the shaft diameter to the upper value.
4.Zero clearance or negative clearance increases
the frictional resistance slightly. if the negative
clearance is too tight, the deformation of the
outside cylinder will become larger,to shorten
the bush life.
2.Housing
There is a wide range of housings differing in
design, machining, and mounting. For the fitness
and shapes of housings, see Table 2 and the
following section on mounting.
1.Shaft
Japan Japan
TECHNICAL INFORMATIONTECHNICAL INFORMATION
When inserting the linear bush into the housing, do not
hit the linear bush on the side ring holding the retainer
but apply the cylinder circumference with a proper jig
and push the linear bush into the housing by hand or
lightly knock it in. (See Fig.1) In inserting the shaft after
mounting the bush, be careful nto to shock the balls.
Note that if two shafts are used in parallel, the parallelism
is the most important factor to assure the smooth linear
movement. Take care in setting the shats.
Mounting
Examples of Mounting
The popular way to mount a linear bush is to operate it with an appropriate interference. it is recommended, however,
to make a loose fit in principle because otherwise precision is apt to be minimized. The following examples (Figs. 2 to 6)
show assembling of the inserted bush in terms of desinging and mounting, for reference.
