Types of Roller Bearings

Types of Roller Bearings Points : Types of Roller Bearings, Needle Roller Bearings, Tapered Roller Bearings, Spherical Roller Bearings, Cylindrical Roller Bearing Following are the principal types of roller bearings:
1. Needle Roller Bearings
2. Tapered Roller Bearings
3. Spherical Roller Bearings
4. Cylindrical Roller Bearing
1. Needle Roller Bearings These bearings are comparatively slender and fully fill space thus that neither a cage nor a retainer is required. This bearing is use while heavy load is to exist approved with an oscillatory motion like piston pin bearing into heavy duty diesel engines, wherever the exchange of motion tend to remain the rollers in right position.

2. Tapered Roller Bearings Rollers with race conduct of this bearing are reduced cones whose element intersects at a ordinary position. Such type of bearing preserve takes both radial and thrust loads and this bearing is accessible in different mixture as twice row bearings and by dissimilar cone angle used for use with dissimilar virtual magnitudes of radial and thrust loads.

3. Spherical Roller Bearings This bearing be self-aligning bearing. Self-aligning characteristic is realized in grinding one of the races in the shape of ball. This bearing is able to usually bear angular misalignment and while use with a twice row of rollers, these preserve take thrust loads in each direction.

4. Cylindrical Roller Bearing This bearing contains small rollers direct in a cage. This bearing is comparatively, stiff next to radial movement and has the lowly coefficient of friction some form of serious duty rolling-contact bearings. Roller bearings are use in high speed service.
