There are many types of bearings available in the markets like deep groove ball bearings, angular contact ball bearings, self aligning ball bearings,roller bearings, spherical roller ball bearings, taper roller bearings, thrust ball bearings etc.The selection of ball and roller bearings for required installation depends upon following factors.
Nature of load, speed of shaft, expected life of bearings, nature of environment where which is working.
After considering the above factors that the ball bearings used for small machinery running at high speed, and while roller type bearings which is used under placing heavy loads machinery.

Selection criteria for each type of bearings :
Deep Grove ball bearings : used under radial and thrust load, the thrust load can be up to two third of radial load.
 |
| Deep groove ball bearing |
Angler contact ball bearing : which type of bearings used for combination of radial and thrust loads, heavy thrust loads depends on contact angle. Bearing having large contact angle which can be suitable for heavy load applications
 |
| Angular contact ball bearings |
Self aligning ball bearings : which can be used for primarily radial loads where self aligning + /- 4 required. Care should be taken when selecting of these type of bearings as thrust loading greater then 10% of radial loads which cause the failure.
 |
| Self aligning ball bearing |
Spherical roller bearings : these type of bearings mostly suitable for heavy duty of radial loads and moderate thrust their internal self aligning feature is use full in many types of applications such as HVAC Fans.
 |
| Spherical roller bearing |
Cylindrical roller bearings : Which is normally used for heavy . Especially these type of bearings use full for axial movement of shaft
 |
| Cylindrical roller bearing |
Taper roller bearings : it is used for heavy thrust and radial loads . The bearing is designed so that all elements in rolling surfaces the raceways intersect at common point on axis thus true rolling is obtained.
 |
| Taper roller bearing |
Thrust ball bearings : May be used for low speed application and where other bearings carry the thrust loads.
 |
| Thrust ball bearing |
Straight roller thrust bearings : these bearings made of series of small rollers to minimize the skidding which cause twisting of rollers they may be used for moderate speeds and loads.
 |
| Straight roller thrust bearing |
Needle bearings : This type of bearings have with rollers whose length is at least 4 time of their diameter.They are most use full where space is factor and available with or without inner race it, the shaft is used as inner race , which is hardened and ground. Full compliment type is used high loads , oscillating or slow speed , cage type of should be used for rotational motion, these can not suitable and support the thrust loads .
