Split-housing pillow block tapered roller bearings have cartridge inserts that are replaceable without dismantling the system. The base of the bearing mounts to a surface that runs parallel to the shaft that the bearing holds. Pillow block bearings allow the shaft to rotate smoothly while the base supports the load. Tapered roller bearings can support heavy radial, axial, or thrust loads encountered in industrial precast, mining, and conveying applications.
