Description
Rotary FC555-1 Aftermarket Runway Sheave Pin for Rotary 4-Post Lifts
The runway sheave pin (also called a pulley pin) is a critical component in Rotary 4-post vehicle lifts. Positioned beneath the runways, these pins secure the cable sheave (pulley) assemblies that guide and tension the lifting cables. Over time, pins can wear, corrode, or develop play — replacing a worn sheave pin restores smooth cable operation and safe, reliable lift performance. This aftermarket replacement is manufactured to meet or exceed OEM specifications and is finished in black oxide for corrosion resistance.
