Mast Guide Bearings Information

Sealed mast guide bearing

Mast guide bearings are bearings with a thick cross section that are typically used as guide rollers in high radial or thrust load applications. The outer ring is used as a wheel directly against a steel mast rail.

The most common application for mast guide bearings is to guide the telescopic mast section in forklifts. Due to the demanding operating conditions, mast guide bearings must be designed to withstand high radial and thrust loads, as well as occasional shock loads.

Mast guide bearings are designed for low speed, high load operation. In order to withstand these conditions, their ball or roller rolling element is configured in a maximum load-bearing capacity arrangement. Bearings are typically greased and manufactured with double seals or double shields.

Mast guide bearings are available in a single row and double row configuration and with a variety of outer ring designs. Outer ring styles include flat, tapered, and specialty designs that feature a corner radius, chamfer, flanges and other designs.
