Groove Gauge for New or Re-Worked Sheaves

For new or re-machined grooves, the groove gauge is nominal plus the full oversize percentage. The gauge carried by most wire rope representatives today is used for worn grooves and is made nominal plus 1/2 the oversize percentage.

This latter gauge is intended to act as a sort of “no-go” gauge. Any sheave with a groove smaller than this must be re-grooved or, in all likelihood, the existing rope will be damaged.
