Y-Bearings Axial Load Carrying Ability

The axial load carrying ability of a Y-bearing depends not so much on its internal design as on the way it is locked onto the shaft.

For Y-bearings with grub screws or an eccentric locking collar, the maximum axial load that they can support is approximately 20% of the basic dynamic load rating if an unhardened shaft is used and the grub screws are properly tightened.

When a Y-bearing is mounted on an adapter sleeve, its axial load carrying ability depends on the amount of torque used to tighten the lock nut. If the torque prescribed in the product tables is used, the axial load carrying ability will be between 15 and 20% of the basic dynamic load rating.

Where an abutment on the shaft supports the inner rings the axial load carrying ability depends on the nature of this abutment. Generally, however, the axial load on the bearing should not exceed 0,25 C0.
