Milwaukee Roller
Model Number: 42-40-2052
The Milwaukee 42-40-2052 is a genuine OEM Roller for use in compatible Milwaukee tools. The roller is a cylindrical rolling element used at a specific interface in the tool's mechanism — providing low-friction rolling contact between two components to reduce wear and allow smooth relative motion. Rollers are used in Milwaukee tools at cam interfaces in impact mechanisms, belt drive systems, guide rollers in reciprocating mechanisms, and lower guard contact points in circular saws, where rolling contact reduces friction compared to sliding contact. The roller must spin freely on its axle and maintain its cylindrical profile for consistent, smooth rolling contact. A worn, seized, or deformed roller that causes increased friction or rough mechanism operation requires replacement to restore smooth rolling at the interface it serves.
Using a genuine Milwaukee OEM roller ensures the correct diameter and axle bore for the rolling interface it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct roller for your specific unit.
