How does the CRBS bearing compare to using two ball bearings back-to-back?

A single CRBS bearing replaces the function of two back-to-back angular contact ball bearings plus separate mounting hardware, reducing parts count by more than 50%, halving the axial footprint, and significantly increasing overall system rigidity and alignment accuracy.

Do CRBS bearings come pre-lubricated?

Open-type bearings are shipped unlubricated from the factory, allowing customers to select the optimal grease for their specific application. Sealed types (UU/U/ZZ) leave the factory pre-packed with premium grease and ready to install.

Key features

Slim cross-section with small OD and width, saving 30%-50% mounting space compared to conventional bearings; ideal for space-constrained designs.

A single bearing supports radial, axial and moment loads simultaneously, eliminating the need for complex bearing combinations and simplifying mechanical design.

3-4 times higher rigidity than standard bearings; minimal elastic deformation under load, ensuring long-term precision and stability.

Split inner/outer ring design for easy assembly; adjustable clearance and optional preload for optimal rigidity and accuracy.

Product Q&A

Q:Are you a factory or trading company?

We are a professional manufacturer with our own export team. We control production, quality and delivery directly, so you get competitive price and reliable service.

Q:What makes CRBS different from RB, RE, and CRBH series crossed roller bearings?

The CRBS series is specifically designed as a super-thin/slim profile with smaller cross-section heights (8mm and 13mm), enabling installation in the tightest space constraints. The inner ring has an integrated flange with mounting holes for convenient bolting, while the outer ring is one-piece integral. By contrast, CRBH has thicker profiles for higher load ratings, RB uses a split outer ring, and RE uses a split inner ring.

Q:What precision grades do you offer for CRBS bearings?

We supply CRBS bearings in P5 (standard industrial), P4 (high precision), and P2 (ultra-precision) grades per ISO Abt. 4. P4 grade bearings feature radial runout 0.003mm, suitable for demanding robotic and optical applications.

Q:Can you manufacture CRBS bearings in stainless steel?

Yes. We offer CRBS bearings in both GCr15 carbon chromium steel (standard, for general industrial use) and SUS440C stainless steel (for corrosive, washdown, or clean-room environments).

Q:What is your MOQ for CRBS bearings?

There is no minimum order quantity for standard catalog models,you can purchase as few as 1 piece. For fully custom non-standard orders, MOQ varies by specification; please contact us for details.
