Non-rotating stabilizer (rubber sleeve stabilizer) is a special tool in drilling to avoid blade wear and wall damage. The non-rotating stabilizer consists of mandrel, copper washer, rubber sleeve, spacer sleeve and self-locking lower sub.

A locking clutch (self-locking lower sub) will avoid sleeve rotationg during wash over operation.
