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)
