Brand: Uhing (made in Germany)

Uhing Linear Drive Nuts (RS) are non-positive drives which convert the rotation of a plain round shaft into linear motion. This effect is achieved by pressing specially crowned Rolling Rings against the shaft and allowing them to roll on the surface of the shaft at an angle which determines the pitch.

Suitable for use as an actuator for: linear motion drives, measurement and inspection technology, materials handling systems, control systems, medical engineering etc.

Main advantages of the Uhing Linear Drive Nuts:

  • Backlash-free
  • Resistant to vibrations
  • Compact design
  • Overload protection
  • High-efficiency
  • Quiet in operation
  • Low maintenance
  • Free-movement lever
  • Good sealing possibilities
  • Linked nuts for higher side thrust
  • Left and right-hand pitch on the same shaft

Step One: Select your desired model from the above table

Step Two: Select the Direction of Shaft Rotation, either Left (L) or Right (R)

Step Three: Select the pitch based on your requirements, available pitch – 0.1, 0.2, 0.3, 0.4 or 0.5 (this is the standard) of the shaft diameter

Step Four: Decide if you require a Free Movement Lever (F)
