The spherical roller thrust bearings 29400 types are of separable design; the shaft washer with roller and cage assembly, and the housing washer, can be mounted individually. It features self-aligning, and can accommodate misalignment of the shaft relative to the housing which can be caused by shaft deflection. Thrust roller bearings usually adopt steel pressed cages or machined solid cages. And they can carry combined loads which is main in axial and axial loads in one direction. Their loading capacity and limiting speed are high, and they can align by themselves when the precision of shafts or housing is not high or there is installation error.

The permissible misalignment is reduced as the load increases. Guideline values for misalignment and rotation of the shaft washer relative to the housing washer, so the buyer can check it before purchasing.

In order to extend service life and accommodate working conditions, 29400 series spherical roller thrust bearing substantially improved the performance by optimizing the internal geometry and surface finish of all contact surfaces, combining the adoption of high standard steel with a salt bath quenching, perfecting the cage, roller profile and the geometry of the raceways.

This type of thrust roller bearings have improved in the following aspects: higher load carrying capacity, better wear-resistance, reduced noise and vibration levels etc.

Application

29400 series spherical roller thrust bearing is extensively applied on the industries as marine gearbox, water turbines, electric motors, fans, marine propeller shaft, industrial gearbox, plastic machinery, rubber machinery, rolling mill, crusher, tower crane, engineering machinery, construction machinery, oil rig, vertical motor, hydroelectric generator and so on.
