the sealed rt turntable x-type 4-point contact bearing is a single row ball bearing. this bearing can withstand moment loading. the rt turntable x-type bearings have been created using a gothic archway. the gothic archway allows for moment and reversing axial loads to be accepted. rt turntable x-type bearings are not an ideal solution for radial loads or combined radial and thrust loads.
typically the rt turntable x-type 4-point contact bearing is provided with aisi-440c rings, a brass cage separator, ptfe seals, mil-g-81322 lubricant and an abec 1 rating class. options abound with variations available in:
- lubricant and fill rate
- cage material and ball material
- bore size
- no gearing, external gear or internal gear design
- mounting holes
- seal material
- precision class
- diametral clearance (internal fit)
