P4 Precision Crbh Series Integrated Ring Crossed Roller Bearing for Robot Joint

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.

The CRBH series features integral (one-piece) inner and outer rings with no mounting holes, whereas RB uses split outer ring + integral inner ring, and RE uses integral outer ring + split inner ring. The CRBH's one-piece design eliminates potential alignment issues and offers superior compactness , ideal for applications requiring both rings to rotate.

Yes. We manufacture CRBH bearings in P5, P4, and P2 accuracy grades. Please specify your required tolerance class when placing your order.

Absolutely. We accept custom orders for non-standard dimensions, materials (e.g., stainless steel for corrosive environments), seal types, preload levels, and cage materials. Submit your drawings or specifications for a quote.

The CRBH bearing is mounted by clamping the inner and outer rings against precision-machined flanges axially. Ensure the mounting surfaces are flat, perpendicular to the axis, and within specified tolerance to avoid distortion. Avoid hammering directly on the bearing.
