Replacement Bearings for Setscrew Locking Series

Mounted Bearings offer a simple, convenient method of
providing load support. Selection for most applications
may be readily accomplished from a single selection
chart, based on shaft size, radial and thrust load
requirements. Installation normally requires only bolting
to a suitable mounting surface and securing bearing to
shaft with setscrews or eccentric locking collar provided.
The Boston Gear Mounted Bearing line is one of the most
comprehensive available to industry. Ranging from light
duty, plain bearing blocks to precision units. They all
