- L = Length of Rail
- P = Pitch of Rail (distance between mounting holes on center)
- E = “E” Dimension (distance from the edge of the rail to the first mounting hole on center)
Genuine HIWIN QR Series Rail
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.
