Cooper split roller bearing pedestals
PEDESTALS
Pedestals (also known as Pillow Blocks) are the most common method of mounting Cooper split roller bearings. Pedestals are common between expansion (EX) and fixed (GR) units.
Pedestals should be fully supported on a flat, rigid surface to avoid distortion of the pedestal or deflection under load. The flatness of the supporting surface should be to tolerance IT7 according to ISO 1101 and the surface roughness not more than 12.5µm Ra.
