General Information ...

After knowing all about the Bearings the important thing is the proper selection of Bearings for any moving vehicle or machine. The selection of ball & roller Bearings for a given installation depends upon the following factors.

  1. The load-carrying capacity and the nature of the load.
  2. The speed of the shaft in r.p.m.
  3. The type of service under given condition such as temperature, humidity, dustiness, acidity, etc.
  4. The anticipated life of the Bearings.
  5. Magnitude and direction of loads.
  6. The proportion of thrust to redial load.

Considering the above factor, generally Ball Bearings are suitable for small machines running at high speed while Roller Bearings are suitable for machines to be placed under heavy loads.

i. Deep groove or Angular Contact Ball Bearings are suitable where comparatively heavy thrust loads are to be carried at high speed.
ii. Self-Aligning Ball Bearings & Spherical Roller Bearings are suitable for such parts as are apt to be subjected to permanent bending or warping and fluctuating misalignment occurs between shaft and Bearings housing.
iii. Cylindrical Roller Bearings are suitable for those shafts which have been allowed to move freely longitudinally within certain limits, and for far longer and heavily loaded application.
iv. Taper Roller Bearings are suitable where radial and thrust loads or any combination of both are required to be handled and in dealing with heavy composite loads as in case of automobile parts.
v. Thrust Ball Bearings are suitable for arrangements put under light axial loads.
vi. Ball Bearings with pressed cages which are light in weight and have high elasticity are suitable at normal speed.
vii. In very high speed spindles and machines only, Bearings with precision tolerances are used.
viii. Ball Bearings with mechanical brass cages are more suitable high speed.

The capacity of the Bearings decreases as the speed increases if a ball Bearings operates continuously, its life expectancy measured in hours will obviously be shorter than if operated intermittently. Some types of Bearings can carry only radial loads or thrust loads while some types of Bearings can carry both radial as well as thrust loads. So if a Bearings which can carry only thrust loads is put under radial loads, it will either break or damage the machine into which it is fitted. So a proper selection is necessary. One major cause of Bearings failure lies in the improper selection of Bearings.

In short the proper selection on Bearings is most essential and will ensure the longer life of the Bearings as well as the life of the machine in which it is used. If the Bearings loads with its directions of the ratios of radial and thrust capacity and speed is accurately determined, its life span can also be established. The necessary Bearings size can also be determined. However the selection is so complex that general rules can hardly be drawn up.
