CRBD Series
CRBD Split Outer Ring Crossed Roller Bearing with Mounting Holes
- Type
- Split outer ring, mounting holes (CRBD)
- Bore Diameter
- 20 - 160 mm
- Dynamic Load Rating
- 8.26 [kN] - 102 [kN]
- Accuracy Grades
- P5, P4
Split outer ring with mounting holes (CRBD): Consists of an inner ring and two outer semi-rings with mounting holes. The mounting holes allow the crossed roller bearing to be fixed directly, and it is suitable for rotating the inner ring.
CRBA is the same split-outer-ring core without mounting holes, for housings that clamp the bearing. View CRBA Series →

Sizes
Bearing numbers encode bore and width: CRBD 08022 is an 80 mm bore, 22 mm wide. The suffix letter is the mounting-hole execution: A (threaded inner ring) covers all seven sizes, B and C (counter-bores both rings, same or reverse direction) start at the 80 mm bore. Every size comes sealed (WW) or open (NN), in clearance C8 or C1.

Part numbers & options
How a part number reads
CRBD 080 22 A WW C8 P5
- CRBD
- Model code — CRBA split outer · CRBB split inner · CRBC high rigidity · CRBD split outer with mounting holes · CRBE high rigidity with mounting holes · CRBX customized
- 080
- Bore diameter — 080 = 80 mm (20 to 160 mm for CRBD)
- 22
- Width — 22 = 22 mm
- A
- Mounting holes — A threaded inner ring, counter-bored outer · B counter-bores both rings, same direction · C counter-bores, reverse direction
- WW
- Seals — WW sealed both sides · NN open (both keep oil holes)
- C8
- Axial internal clearance — C8 negative, zero backlash · C1 positive, low friction
- P5
- Accuracy class — P5 · P4 (CRBD standard grades)

Accuracy grades
CRBD runs P5 and P4; contact HIWIN for higher grades.
- P5 Standard — Inner-ring radial runout 4-8 µm by size
- P4 High — Inner-ring radial runout 3-6 µm by size
Internal clearance
- C8 Negative (preload) — Zero backlash for indexing and joints
- C1 Positive — Lower friction torque under light duty
Seals
- WW Sealed both sides — Keeps the track clean, retains grease
- NN Open — Lowest friction for low-torque axes
Mounting holes
- A Threaded inner ring — Counter-bored outer ring; all seven sizes
- B Counter-bored, same direction — Both rings; sizes 08022 to 16035
- C Counter-bored, reverse direction — Both rings; sizes 08022 to 16035
