Product Description

Cheap Sheave Problem
Our Sheave Solution
Soft groove → rope rubs & frays in weeks
Hardened groove surface (HRC 45-50) – rope slides smoothly, lasts 3x longer
Open bearings → dust/water enters → seizes
Double-sealed bearings – works in rain, dust, coastal salt air
Wrong groove size → rope jumps/squeals
Precision groove match – we size groove to YOUR rope diameter (±1mm tolerance)
