Roll Ring Traverse Unit Special Bearing,Rolling Ring Traverse Drive,Smooth Shaft Traverse Unit
The bearings sit on a smooth, unthreaded shaft. Bearing angle determines travel direction and the linear pitch of the drive.In either fixed or variable-pitch rolling-ring linear drives, the drive unit sits on a smooth, unthreaded shaft. olling-ring bearings are machined with a specially shaped ridge that contacts the shaft at a single point.On Amacoil-Uhing variable-pitch rolling ring drives, the linear-pitch control lever is manually adjusted to a setting on a scale.
