Axial load carrying ability
The axial load carrying ability of Y-bearings depends not so much on their internal design as on the way in which they are locked on the shaft.
For those bearings with grub screw locking or eccentric locking collar, the maximum axial load which they can support is approximately 20% of the basic dynamic load rating C, if unhardened shafts are used and the grub screws properly tightened when mounting.
For Y-bearings mounted on adapter sleeves the axial load carrying capacity depends on the tightening torque used for the lock nut. If the torque prescribed in the product table is used, the axial load carrying capacity will be between 15 and 20% of the basic dynamic load rating.
The axial load carrying ability of the Y-bearings for extreme temperatures of the VA201 and VA228 designs is approximately 15% of the basic static load rating C0 because of the large radial internal clearance.
Where the Y-bearings are supported by an abutment on the shaft, the axial load carrying capacity depends on the nature of this abutment. Generally, however, the axial load should not exceed 0,25 C0.
