The PRS specializes in manufacturing of bearings, including slewing ring bearing, crossed roller bearing, turntable bearing, wire raceway ball bearing, etc. The four-point contact ball bearing has highest static load capacity . The crossed cylindrical roller bearing has highest dynamic load capacity . The pre-interference of the crossed tapered roller bearing makes it sustain highest stiffness and rotating precision. Three-row cylindrical combined roller bearing leads to bearing height because of the increasing loading capacity. The different raceways sustain relative forces.
