Cylindrical Needle Rollers Supplier

Needle rollers give smoother motion in two ways when used with recirculating profiled rail bearings. First, needle rollers have greater dynamic friction than balls or cylindrical rollers from Cylindrical Needle Rollers Supplier. Although higher running friction is a disadvantage in some applications, it can be advantageous in high-load, high-rigidity linear guides because it dampens vibrations caused by external forces. And, as the load is distributed over more, smaller rollers, the vertical pulsation of the bearing generated by roller motion is decreased.
