The raceway finish by grinding, the high level machining process and grinding process that ensured the precision for the double row slewing rings.

Mining equipment are characterized by their tough working conditions, like high temperature and heavy dust, and they are usually heavy-duty machines requiring slewing ring bearings of high load capacity.

 The clearance cage enables the friction between rollers to be disappeared and prevent rollers from falling down on one side, which is able to obtain a stable torque. The rollers are orthogonal arranged, so only one set of the Crossed Roller Bearings can withstand the loads from different directions. Compared with the traditional series bearing, the current series bearings have increased the level of rigidity by three to four times.
