Cylindrical Roller Bearing
Characteristics :
In this type of bearings, the rollers race tracks are essentially cylindrical, however they may be ground slightly curved in order to achieve thereby small degree of flexibility.
The rollers are guided between two lips on either the inner race or the outer race. Other types provided with either no lip, one lip or two lips, according to the function which the bearing has to perform. Ball Bearings have a point contact on the races whereas all types of cylindrical roller bearings have a line contact.
Due to line contact the cylindrical roller bearings have a very high radial load carrying capacity as compared to ball bearings of the same size. Due to their separable design, cylindrical roller bearings are more convenient for mountings than ball bearings.
Application:
These bearings are mainly used in medium and large size motors, electricity generators,internal combustion engines, gas turbines, machine tools, spindles, reducers, unloading and lifting machines and other industrial machinery.
Types :
Cylindrical roller bearings can be classified into following types :
Single-row cylindrical roller bearing
Double-row cylindrical roller bearing
Four-row cylindrical roller bearing
