Shaft Bearing Assembly – TN387387

A shaft bearing assembly supports a rotating shaft, combining the bearing and its housing into a single unit that locates the shaft and lets it turn under load with minimal friction. Supplied as an assembly, it installs as one piece rather than pressing a loose bearing into a separate housing, so the bearing arrives already set in its mount and aligned. It serves the rotating shaft on Tennant equipment, where a bearing that has roughened or developed play shows up as noise, vibration, or a shaft that no longer turns true.

A shaft bearing is replaced once it loses smooth rotation, since a failing bearing loads the shaft and the components it drives. Match the assembly's bore to the shaft it carries and its housing to the mounting it bolts into, since both the shaft fit and the mount have to line up for the unit to seat and run true.
