The XR Series Cross‑Roller Ring is a Kaydon‑derived bearing designed for four‑point contact replacement. It features cylindrical rollers positioned in a V‑shaped groove with alternating axes, allowing simultaneous radial, thrust and moment load acceptance. The design yields lower rotational torque and higher stiffness within a compact envelope. Availability is on a custom‑manufacture basis to match the buyer’s hole pattern and optional gear‑teeth options.
FRB Bearings typically fabricate the rings from chrome steel (AISI 52100) hardened to 58‑62 HRC, which is standard for high‑performance cross‑roller bearings. Typical roller diameters range from 5 mm to 30 mm, giving dynamic load ratings between 10 kN and 200 kN. The V‑groove geometry provides a larger contact area than ball bearings, increasing rigidity. Industry practice calls for lubrication with high‑temperature greases compatible with steel.
The XR rings are used in radar and military turrets, precision machine tools and tunnel‑boring machines where extra stiffness and low torque are critical. Buyers such as defence contractors, equipment manufacturers and OEMs often request custom bore sizes and optional drive‑gear integration. Trade terms are negotiated directly with FRB Bearings; confirm minimum order quantities, lead times and Incoterms before placing an order.

Before placing an order with FRB Bearings, importers should obtain a current factory audit report, confirm the material grade and hardness certificates, and verify that the custom hole pattern matches their drawing. Request a sample or technical drawing to ensure dimensional compatibility. Because the supplier’s response rate is low, allow extra time for clarification on specifications and documentation.
Shipping terms, lead times and Incoterms are not disclosed in the listing and must be negotiated directly. Ask the supplier to specify the port of loading in China, typical transit time to your destination, and whether they can arrange container consolidation. Clarify accepted payment methods, such as T/T or letter of credit, and any advance deposit requirements.
Arrange an independent third‑party inspection at the factory or upon arrival to verify roller diameter, hardness and surface finish against the supplied certificates. Request a mill test report and, if needed, a functional test under load to confirm stiffness performance. Ensure that the final documentation includes a certificate of conformity and a packing list matching the order.
