Dewalt 872789 Shoulder Bearing

Product Description

The DEWALT 872789 is a shoulder bearing designed as an internal replacement component for DEWALT power tools. Shoulder bearings support rotating shafts and reduce friction between moving parts, maintaining alignment and load distribution within the tool assembly. This part is installed by technicians performing mechanical repairs on DEWALT power tools and is intended to restore original performance when the existing bearing shows wear, damage, or failure.

The 872789 is used in power tool repair and maintenance applications. It fits within the internal drive or spindle assembly of compatible DEWALT tools where a shoulder bearing is specified. This component is typically sourced during bench repair or field service when worn bearings cause excessive play, noise, or heat in the tool.
