Product description

The Rotary Antifriction Washer is a specialized nylon spacer designed for the high-tension pulley stacks on 4-post lifts. This 1/8-inch thick washer, with a 4-inch outer diameter, fits perfectly on 1-1/2-inch pins, providing a smooth, low-friction surface between moving sheaves. Its primary function is to prevent metal-on-metal contact and binding within the pulley assembly, ensuring the lifting cables can transition smoothly as the lift raises and lowers. Made from durable, industrial-grade nylon, it resists deformation and maintains its lubricity even under heavy pressure. Replacing worn or missing washers is a simple yet critical step in preventing pulley noise and premature cable fraying. This SVI washer is a direct-fit replacement for both Rotary and Challenger brand 4-post lifts, ensuring your lifting system remains synchronized and efficient.
