Roller Linear Guide Rail
Roller lm guideways adopts roller as rolling elements instead of steel balls, can offer super high rigidity and very high load capacities, roller bearing slide rails are designed with 45 degree angle of contact which produces small elastic deformation during super high load, bears equal load in all directions and same super high rigidity. So PRG roller guideways can reach super high precision requirements and longer service life.
