Loads Roller Pillow Block Bearings
Orientation & Cantilever Loads When a linear motion system is subjected to a cantilever load or moment, the system designer must take into consideration these type of loads will greatly affect the performance of the system. Roller Pillow Blocks are not suitable for these types of applications because the moments will load the side rollers and cause premature failure. If the moments or cantilever loads are minor, loads may be acceptable. For this reason we ask that you consult the factory.

Note: Shock, vibration, and moments may affect the life of the pillow block.
Note: Chart is rated at 10% accuracy. Figures are based on a safety factor of one.
