Recirculating Unit Type NRT and Preload Wedge type NRV - Product Information

Minimal lateral forces due to independent tracks, low roller play, and an optimal ratio of length to diameter.

Designed for medium and heavy loads due to low travel pulsation.

Two independent tacks, low roller play, and the optimal ratio of roller length to diameter to ensure minimal lateral forces with Type NRT roller recirculating unit. They are designed for medium to heavy loads. A greater number of rollers and optimized roller feed results in low travel pulsation. Type NRT scores with its low coefficient of rolling friction, high load carrying capacity - 4300 N to 181000 N, and high rigidity provided by triple support on the back and protected roller return. Type NRT is made of fully hardened tool steel and is also available in pairs, arranged within 5µm. Lubrication is provided by nipples on the facing sides and openings at the back. An optional connection for centralized lubrication is also available. There is a double-lipped, replaceable dirt wiper on all facing sides. The NRV preload wedge complements the drive element. The sophisticated design with concave/convex surfaces compensates for minor angular errors and deformations in the connection structure.
