Misalignment

The structure of 29300 series spherical roller thrust bearing features self-aligning, and can accommodate misalignment of the shaft relative to the housing which can be caused by shaft deflection ect (Fig.8).

The permissible misalignment is reduced as the load increases. Guideline values for misalignment and rotation of the shaft washer relative to the housing washer listed in table 1.

When designing bearing arrangements with rotating housing washer in combination with misalignment or when the shaft wobbles relative to the housing, contact JCB. Whether these values can be fully exploited depends on the design of the bearing arrangement and the external sealing design ect.

Impact Resistance Performance

In order to extend service life and accommodate working conditions, 29338/YA8 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.

Embodied in:

  1. Higher dynamic load carrying capacity
  2. Improved wear-resistance
  3. Reduced noise and vibration levels
  4. Less frictional heat
  5. Significantly extended bearing service life

Applications

Our products,29338/YA8 spherical roller thrust bearing is extensively applied on the industries as marine gearbox, 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.
