CROSSED ROLLER SLEWING RING BEARING

LYPRS Bearing manufactures ball and roller type slewing ring bearing.There are five types according to their configurations.

●?? single-row four point contact ball slewing ring

●?? double-row ball slewing ring(with same diameter or different diameters balls)

●?? single-row cylindrical crossed roller slewing ring

●?? three row cylindrical roller slewing ring

●?? roller/ball combined slewing ring

?The PRS slewing bearing has four series. There are four-point contact ball bearing (no-gear, outside gear ,inside gear ) ,double row angular contact ball bearing ,crossed cylindrical and tapered roller bearing and three-row cylindrical combined roller bearing .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.
