Bearings: Solid Pillow Block Bearing (Spherical Roller Element)
Pillow block bearings are designed to provide shaft support where the mounting surface is parallel to
the shaft axis. The bolt holes are usually slotted for adjustment during mounting. The rolling element
in these pillow block bearings has a crowned or spherical shape. Spherical-roller pillow block bearings
are superior when dealing with high loads and loads that require tolerance to shock; however, they
have limited speed capabilities.

Bearings: Split Pillow Block Bearing (Ball Type Element or Spherical Roller Element)
Also known as bearings with split pillow block housings, the pillow block housing is split for easy
bearing replacement and inspection.

Bearings: Totally Split Roller Bearing
Totally split roller bearings are completely split to the shaft. All internal bearing parts split into TWO
HALVES, allowing for easy removal of internal bearing parts without totally removing the shaft.
