The sealed RJB X-Type 4-Point Contact Bearing is a single row ball bearing.  This bearing can withstand moment loading. The RJB X-Type bearings have been created using a gothic archway. The gothic archway allows for moment and reversing axial loads to be accepted. RJB X-Type bearings are not an ideal solution for radial loads or combined radial and thrust loads.

Typically the RJB X-Type 4-Point Contact Bearing is provided with a brass cage separator, PTFE seals, MIL-G-81322 lubricant and an ABEC 1 rating class. Options abound with variations available in:

• Material type for rings, seals and rolling elements
• Lubricant and fill rate
• Bore size
• Seal material
• Precision class
• Diametral clearance (Internal Fit)
