Bases – Unitary Base
Utilizes structural channel to support the fan assembly and are designed for use without isolators.

Bearings: Solid Pillow Block Bearing (Ball Type Rolling 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. Ball Type Pillow
Block Bearings have a ball as the rolling element. They are used to provide smooth, low friction
motion in rotary applications.

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.
