Split inner ring type (CRBB): Consists of two inner semi-rings and an outer ring, which is suitable for rotating the outer ring.
Rotating the inner ring instead? CRBA is the mirror construction: one inner ring, two outer semi-rings. View CRBA Series →

Part numbers & options
How a part number reads
CRBB 080 16 WW C8 P5
- CRBB
- Model code — CRBA split outer · CRBB split inner · CRBC high rigidity · CRBD/CRBE with mounting holes · CRBX custom
- 080
- Bore diameter — 080 = 80 mm (30 to 400 mm for CRBB)
- 16
- Width (mm)
- (blank)
- Mounting holes — always blank on CRBB · A/B/C apply to CRBD and CRBE only
- WW
- Seals — WW sealed both sides · NN open (both keep oil holes)
- C8
- Clearance — C8 negative, zero backlash · C1 positive, low friction
- P5
- Accuracy — P5 · P4 · P2 · PD5 (CRBB); family also runs PD4 · PD2
The configurator assembles this number for you, with drawings and 3D CAD. Configure ↗
Accuracy grades
CRBB runs P5, P4, P2 and PD5. Runout is specified on the rotating outer ring: radial runout 8 to 23 µm by size in P5/PD5, down to 3 µm in P2.
- P5 Standard — General automation and fixtures
- P4 High — Robot joints, rotary tables
- P2 Precision — Machine tools, inspection equipment
- PD5 Tight-tolerance grade — Tighter bore and outside diameter tolerances at the same runout as P5
Internal clearance
- C8 Negative (preload) — Zero backlash for indexing and joints; friction rises during unloading
- 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
