The main functions of rolling bearings in gearboxes are to stabilize the shaft and support the transmission of force. This means extreme loads in complex environments must be withstood. Gearbox bearing types mainly include tapered roller bearings, four-point joint contact bearings, cylindrical roller bearings, deep groove ball bearings, spherical roller bearings, and angular joint contact ball bearings. Bearing arrangements vary; mainly based on gearbox design and operating conditions.

The main requirements for bearings used in gearboxes are:
●High speed
●High load
●Resistant to vibration and shock
●High temperature resistance
●High guiding precision
●Compact design

The characteristics of gearbox bearings are:
●Enhanced internal design
●Special cage design
●Reduce tolerance and adjust internal clearance
●The outer ring is designed with a stop groove to prevent it from rotating
