The roller recirculating units NRT are designed for medium to heavy loads, high rigidity and high precision. Together with suitable SCHNEEBERGER linear bearings, adjusting wedge or attaching part ingenious constructions can be realized.

These wedges are used normally to adjust the preload. At the same time, by suitably shaping the cylindrically ground wedge bars, small angular deviations and deformations in the surrounding construction can be compensated. The parts are made from hardened steel.

Standard version

The design of the twin race recirculating unit type NRT, is based on a through hardened, highly accurately ground steel careier and two plasic components to recirculate the rollers. On each front face there is a double lipped wiper and a lubricating nipple. There is also an additional lubricating hole in the roller return passage.
