Mechanical Components

Crossed Roller Bearings

An outer ring, an inner ring, and rollers separated by spacers: the rollers sit at 90 degrees so one bearing takes radial, axial, and moment load without the rollers rubbing. Six types cover split outer, split inner, high rigidity, mounting holes, and custom envelopes, from 30 mm to 300 mm bore.

Three circular metal components, two silver and one black, with multiple holes and grooves, are arranged on a plain white surface. The objects appear to be mechanical parts, possibly bearings or housings.

Three metallic, circular mechanical components with multiple holes are arranged on a light surface; two are silver and one is black, all featuring a central opening and evenly spaced bolt holes around their rims.

Options & accessories

Options are specified in the part number when ordering.

  • Sealed or open type

    Sealed (WW) keeps contamination out of the track and lubrication in; open (NN) minimizes friction for low-torque applications. Both carry oil holes for lubrication.

  • Clearance & preload

    C1 positive clearance for the lowest friction force, or C8 negative clearance for zero-backlash preload where indexing accuracy rules.

  • Accuracy grades

    P5, P4 and P2 on CRBA and CRBB, P4 and P2 on CRBC, P5 and P4 on CRBD, P4 and P2 on CRBE; PD5 on CRBA/CRBB and PD4/PD2 on CRBC for tighter bore and outside diameter tolerances. Higher grades on request through HIWIN.

Standard, housed mounting

CRBA · CRBB · CRBC

The housing clamps the rings: CRBA splits the outer ring for inner-ring rotation, CRBB splits the inner ring for outer-ring rotation, and CRBC makes both rings one piece for the highest rigidity with rotation either way.

A shiny, metallic circular mechanical component with multiple small holes evenly spaced around its perimeter and a large central hole. The part appears to be a precision bearing or flange against a white background.

With mounting holes

CRBD · CRBE

CRBD and CRBE carry mounting holes in the rings, bolting straight to the machine with no housing or clamping discs: CRBD for inner-ring rotation, CRBE with one-piece rings for rotation either way.

Customized

CRBX

CRBX bearings are designed to order: modified structures and surface treatments matched to the operating environment.

Why HIWIN

Every load direction, one compact bearing.

Rollers crossed at 90 degrees

Alternating rollers take radial load, axial load both ways, and moment load at the same time, so one bearing replaces a paired arrangement.

Line contact, minimal deflection

Roller-to-track line contact spreads the load across a large area: less elastic deformation, high rigidity, and longer service life.

Spacers for smooth rotation

A spacer between every pair of rollers prevents mutual friction, keeping rotational torque low and steady.

Accuracy to P2

Accuracy classes reach P2/PD2, and the C8 negative-clearance option runs preloaded with zero backlash for indexing work.
