Mechanically controlled linear drives

A linear speed-control option for Model RG rolling-ring linear drives is for applications that don’t require variable speed. The option lets users fix a specific linear travel speed in one or both directions of travel using set screws which are inserted into the drive housing. No adjustments to motor speed or controls are necessary.

On standard Uhing RG drives, the linear speed is adjustable, independently of motor speed, using the pitch control lever on the drive unit. When the set-screw option is used, extra long hex head screws are inserted into one end of the drive unit. The screw end protruding into the drive unit contacts the rolling-ring bearing assembly and holds it at a specific angle relative to the shaft, giving the drive a fixed linear speed in one direction.
