For smooth backlash-free linear motion, the Model RS4 drive nut is an alternative to screw-based linear-drive systems.
The nut comes in seven sizes for varying payload and linear-speed requirements and is configurable for vertical or horizontal travel. The size of the drive nut determines shaft rotational speeds up to 10,000 rpm. Linear travel speeds of 0.5 to 4.0 fps depend on nut size and payload weight. Axial thrust is 22 to 449 lb. Specially machined Uhing rolling-ring bearings are installed under pressure inside the drive. Constant single-point contact between the bearing and driveshaft result in zero play. The shaft of the RS4 is smooth there are no threads for dirt or debris to become trapped, therefore eliminating clogged or jammed systems. The drives are suited for a range of linear-motion applications, including material handling, winding, test and measurement, parts transfer, and packaging.
