Bearing symbols

The complete bearing designation is composed of prefix symbols, base symbols and suffix symbols. Prefix symbols generally indicate special configurations.Rust-proof materials are indicated with the abbreviation for stainless steel for instance.

The base symbol relays information regarding the bearing series (first two digits) and the bore diameter (last two digits). From code digit 04, the dimension of the bore diameter is five times the value of the bore diameter code digit, for example 6208 indicates that the bore diameter is d = 40 mm.Exceptions are indicated by a forward slash in front of the code digit.

Cage configurations, shields and seals , etc. are encoded in the suffix symbols.The most important suffix symbols are listed in the following table:

Load capacity and service life The fatigue life can be calculated by means of a formula which incorporates the dynamic load rating, the bearing load and the operating speed.

In the advanced method according to ISO 281, the failure probability as well as the influences of material and lubricant are also taken into account by means of the factors a1, a2 and a3.

A lifte-expectancy of 90 % is usually estimated.

As a formula, this is represented for rotating inner ring as follows:

L10h [h] =

N – speed in rpm-1

Cr – dynamic load in N Pr – equivalent bearing load in N

Modified in accordance with ISO 281 L10hmod = a2*a3*L10h (for a1 = 1)

a) The life-expectancies with allocated a1-values are shown in the following table:

b) Heat stabilized bearings usurally feature a lower hardness than standard bearings made of material GCr15 or 100 Cr6 so that an amendment must be made using the factor a2:

Heat stabilizing a2max. temperature 200 °C 0.68max. temperature 250 °C 0.30

c) The lubricant influence factor a3 is higher than 1 under ideal conditions, however, with lower speeds or in case of contamination etc., a clear reduction in service life must be expected (a3<<1).

In special cases please contact our advisory service.

Equivalent dynamic bearing load Pr

Pr = X * Fr + Y * Fa

The factors X and Y are determined via the ratio Fa/Cor.

A few relations are listed in the following table:

Fa/Cor e Fa/Fr <= e Fa/Fr > eX Y X Y

0.01 0.18 2.460.02 0.20 2.140.04 0.24 1.830.07 0.27 1.610.10 0.29 1 0 0.56 1.480.15 0.32 1.350.20 0.35 1.250.30 0.38 1.130.40 0.41 1.050.50 0.44 1.00

For small or miniature ball bearings below d = 10 mm, the load ratio Fa/Cor should not exceed the limit value of 0.25.

Permissible static load

The static load is used to determine the design of the bearing with low speeds or slewing movements.

S0 = Cor / Por max

The static carrying safety S0 should be calculated by means of the following criteria:

operation condition S0

high running precision required >2standard requirements 1low requirements > 0.5

Lubrication

Deep groove ball bearings sealed on both sides feature lifetime lubrication and are therefore maintenance-free.

In this connection it should also be noted that the grease life of the respective lubricant will reduce the service life of the bearing in certain cases.

The standard greases used are lithium soap greases with a mineral oil base and a service temperature range between -25° and +120°C.

It can be necessary, depending on the operating conditions, to use a special grease or even to reconvert to the maintenance operation.

For the high temperatures which kiln truck bearings have to stand, paste-like lubricants such as molybdenum disulphide for example, must be used as a total loss lubrication.

Additionally, the forming of a lubricating film is conditional on a minimum relative speed and can be estimated using the empirical formula n*dm > 10.000.The mean bearing diameter dm is determined from 0.5 * (d+D)

Heavy bearing loads require lubricants with EP-additives which possess optimum friction reducing properties.

Materials

The standard material used for rings and balls is the chromium steel with the designation GCr15.

The following percents by weight are permissible for the most important steel components:

GCr 15

C 0.95 ...1.10%Mn ≤ 0.50%Si 0.15 ... 0.35%P < 0.025%S < 0.025%Cr 1.30 ... 1.60%

This material is designed to withstand an application temperature range of -20°C up to +120°C and is therefore adapted to the respective RS-seal material NBR.

The cages are made of pressed steel and are designed in accordance with overall size as follows:

C Mn Si P S Cr

Designation

08F0.05…0.11 0.25…0.50 <0.03 <0.04 <0.04 <0.1

The rings and balls of bearings of rust-inhibiting design are manufactured of AISI 440C. The cages of these bearings are made of A ISI 304. (Other special materials on request)

AISI 440CC 0.95 ...1.20%Mn ≤ 1.0%Si < 1.0%P < 0.04%S < 0.03%Cr 16 ... 18%

Fits and bearing clearanceBearing clearance

The radial clearance is reduced with the installation of a press fit.

Differences in termperature between the inner ring and outer ring as well as the loads on the bearing also influence the effective bearing clearance.

In principle, a minimum operating clearance is requested with regard to minimum operating noise possible.

It must be taken into consideration, however, that high thrust loads as well as inclined positions can be compensated better with bigger clearance.

The press fit between shaft and inner ring is channelled into the recess of the inner ring, thus reducing the bearing clearance.

When fit via the outer ring, the pinching amounts to approx. 60 % - 90 % of the overlap (values depending on the aspect ratios).

The operation of deep groove ball bearings under preload (= negative clearance) can considerably reduce the service life and lead to premature failure.

Therefore the design generally features reduced operating clearance.
