Uhing®-linear drive nuts (linear actuators) are non-positive drives which convert the rotation of a plain round shaft into a traversing movement.
This effect is achieved by using rolling rings that are mounted on roller bearings and have a specially shaped running surface. These rings are pressed against the shaft so that they roll on the surface of the shaft at a specific angle.
- low noise emission,
- high efficiency due to rolling on the shaft,
- travel and guide units,
- can be freely moved on the shaft by using a release lever,
- compact design,
- installation does not require much space,
- overload protection by slipping, side thrust can be multiplied by coupling several linear drive nuts,
- different pitch settings available,
- pitch can be set for either direction on the shaft,
- good sealing properties against dust, dirt, humidity, etc.
Wherever linear movements are required, the Uhing®-linear drive nuts are a state-of-the-art alternative to hydraulic and pneumatic actuators, chain feeding systems and lead screws.

The New Member of the Uhing Product Range to Reckon With: Linear Drive Nut RS8
For more than 60 years, Joachim Uhing KG has been successful with linear drive technology, above all with the rolling ring drive invented by the company founder. In 1983, the RS linear drive nut was added to the product range, until now for shaft diameters from 10 to 60 millimetres. Due to frequent requests for smaller diameters, Uhing now launches the RS8 for a diameter of eight millimetres....[read more]
One hundred thousandth Uhing drive nut leaves the factory
In late February 2012, the one hundred thousandth drive nut produced was shipped to Singapore. There, the RS10 type item for 10 millimetre shafts will be employed by a measuring machine manufacturer. Such a high number of units manufactured suggests tried and tested technology and specific know-how for the applications the product is implemented in. A review of the product history and a forecast on future trends confirm this impression....[read more]
