Details

Thrust cylindrical roller bearings are separate bearings that can withstand only one-way axial loads and slight impacts and can limit the axial displacement of the shaft (or casing) in one direction and can therefore be used for one-way axial positioning. But its carrying capacity is far greater than the Thrust ball bearing. When Roller Rolling Dynamic Cr, due to the different linear speeds at both ends of the roller, the roller will inevitably produce sliding Dynamic Cr on the ferrule raceway. Therefore, the Limit speed of such a bearing is lower than that of the Thrust ball bearing, and is usually only suitable for low speed. Operation occasions.

Standard design of Thrust cylindrical roller bearings uses metal-made solid cages, and other types or materials of cages are available upon request. Thrust tapered roller bearings can only withstand one-way axial loads and can limit the axial displacement of the bearings in one direction, so they can be used for one-way axial positioning. Compared with Thrust cylindrical roller bearings, the bearing capacity is large and the relative sliding Dynamic Cr is small, but the Limit speed is low.

Thrust cylindrical roller bearings are mainly used in heavy machinery, high power marine gearboxes, oil rigs, vertical motors and other machinery.
