Cylindrical thrust roller bearings can support large thrust loads. They’re commonly found between gears and the housing and spinning shafts in gear sets. Most transmissions use helical gears with angled teeth, which creates a thrust load that the bearing must support.
They are composed of a washer-shaped raceway ring, a shaft washer and a seat washer, cylindrical rollers, and cage assembly. Cylindrical thrust roller bearings are processed with engineered and optimized convex surfaces, so the pressure distribution between the rollers and the raceway surface is distributed correctly. It is used at low speed and can withstand a one-way axial load without restricting the radial direction. The axial load capacity is large, and the axial rigidity is muscular.
Cylindrical thrust roller bearings features:
- Separable design: Shaft washer, housing washer, cylindrical roller, and cage thrust assembly can be mounted separately.
- Extended bearing service life: The roller ends are relieved slightly to modify the line contact between the raceway and rollers to prevent stress peaks.
Applications of cylindrical thrust roller bearings :
- Cone crushers
- Crane hooks
- Extruders
- Gearboxes
- Oil well swivels
- Power drives
- Pulverizers
- Pumps
