Crown Mast Roller Bearing CR448-221 – BR-698

This load roller bearing carries the working load between the mast sections as the upright telescopes. Positioned in the mast channels, it rolls against the rail to support the carriage and its load, turning sliding contact into rolling contact so the mast extends and retracts smoothly under weight. A load roller in good condition keeps the mast tracking true and helps the upright lift without binding or chatter. This roller bearing is sized for Crown lift trucks and serves as a load-bearing contact point in those mast assemblies. Match the roller outside diameter and width to the position you are servicing before installation.
