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.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Fit Engineering:\u003c\/strong\u003e Sized for a perfect fit on 1-1\/2 inch pulley pins used in Rotary 4-post lifts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Build Quality:\u003c\/strong\u003e High-grade nylon construction provides natural lubricity and impact resistance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial Durability:\u003c\/strong\u003e Maintains a consistent 1\/8-inch thickness under high axial loads in sheave stacks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSA Certified Quality:\u003c\/strong\u003e SVI components are manufactured to provide reliable friction reduction in commercial shop settings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter:\u003c\/strong\u003e 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Hole Diameter:\u003c\/strong\u003e 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Nylon Antifriction Washer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Compatibility:\u003c\/strong\u003e Rotary \/ Challenger\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Reference:\u003c\/strong\u003e FC5346-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSVI Part Number:\u003c\/strong\u003e BH-7517-19\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Manufacture:\u003c\/strong\u003e USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e\u003cstrong\u003eDirect replacement models\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotary:\u003c\/strong\u003e FC5346-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSVI International:\u003c\/strong\u003e BH-7517-19\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Models:\u003c\/strong\u003e Fits various Rotary and Challenger 4-post automotive lift sheave assemblies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThis item can be found in:\u003c\/strong\u003e Rotary AR120EL1, Rotary AR120L, Rotary AR120S, Rotary CWA120, Rotary QL4P, Rotary QL4P100, Rotary QL4P101, Rotary SM120, Rotary SM121EL2, Rotary SM121L, Rotary SM121S\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eYou will receive the same product or an OEM-Equivalent that meets the highest standard of the OEM with warranty that will be a direct-fit.
