Product description

This precision-engineered 1-1/2 inch retainer washer is a critical fastener component used in the assembly and maintenance of heavy-duty automotive equipment. Designed for high-load applications, this washer provides a stable bearing surface and ensures that critical components, such as adapters on brake lathes or shafts on tire changers, remain securely held in place during operation. The 1-1/2" internal diameter is machined to tight tolerances to provide a snug fit over the corresponding shaft, preventing unwanted vibration or axial movement. Made from high-strength steel with a corrosion-resistant finish, this retainer washer is built to withstand the rigors of a professional shop environment where it may be exposed to high heat, lubricants, and repetitive mechanical stress. Maintaining the correct retention hardware is vital for the safe and accurate operation of precision machinery like brake lathes, where even a small amount of play can lead to poor surface finishes or inaccurate machining. This part is a direct replacement for manufacturer part number 8109945.
