Upgrade & Restore Your Tire Changer's Pivot Assemblies

The 5"/16" Wave Washer is a heavy-duty mechanical washer engineered to distribute clamping loads evenly and reduce surface friction on moving pivot points and structural joints of professional tire changers.

Regular maintenance and timely replacement of warped, rusted, or scored washers are critical to preventing mechanical binding on main hinge pins and keeping assemblies pivoting smoothly.

Machine Location:

This washer is located directly on vertical hinge pins, swing arm pivot joints, or bead breaker arm cylinders.

Key Features & Specifications

• Hardened Steel Body: Stamped from high-strength steel to resist flattening, warping, or scoring under heavy loads.
