HIWIN QR Series Rail Genuine HIWIN Linear Guideway, QR Series, Rail Product Image

The new QR (RG) series from HIWIN features a roller as the rolling element instead of steel balls. The roller series offers super high rigidity and very high load capacities. The QR (RG) series is designed with a 45-degree angle of contact. Elastic deformation of the linear contact surface, during load, is greatly reduced thereby offering greater rigidity and higher load capacities in all 4 load directions. The QR (RG) series linear guideway offers high performance for high-precision manufacturing and achieving longer service life.
