Slewing Bearing--Single-Row Crossed Rollers Slewing Bearing (Standard Series HJ)

CHARACTERISTIC OF STRUCTUREPERFORMANCE AND APPLICATION
The single-row crossed roller Slewing Bearing is composed of two seat-rings.It features compact in design,light in weight,high precision and small fitting clearance.
As the rollers are 1:1cross arranged,it is suitable for high precision mounting and capable to bear axial force,resultant moment and considerable large radial force.
The single-row crossed roller Slewing Bearings are widely used for hoisting,transporting,engineering machines as well as for military products.
