DPB Crossed Roller Slewing rings are built with V-groove raceways providing two roller paths in each ring. By alternating adjacent rollers at right angles to one another, one-half of the rollers transmit loads in one direction with the other half transmitting loads in the other direction. The crossed roller bearing design provides a higher theoretical dynamic capacity per unit size, greater stiffness, and a lower spring rate than a single roll ball slewing ring design.

CSX series cylindrical cross roller bearing is similar to CRB series. The two separable outer rings are connected by circlips.
The C-Type, radial contact ball bearing is designed with deep grooves to withstand high loads. Although this bearing is used primarily in applications with radial loads, it can withstand moderate axial loads, reversing axial loads, and moment loads.
Thin section Angular Contact Ball BearingsThin section angular contact ball bearing A Type is designed for supporting axial loads. It can also be used in supporting radial or combining radial-thrust application. But this type cant be solely used in sustaining moment loads or reverseing axial loading. It always be used in pairs.
