Available in both regular and thin-type, high rigidity (CRBC) Crossed Roller Bearings consist of an inner ring and an outer ring, which is suitable for rotating both the inner ring and outer ring.
CRBE adds direct mounting holes to the same high-rigidity one-piece rings, no clamping brackets required. View CRBE Series →

Sizes
Bearing numbers encode bore and width: CRBC 08016 is an 80 mm bore, 16 mm wide. A trailing L marks the thin type, six sizes from 50 to 100 mm bore, all 8 mm wide. Every size comes sealed (WW) or open (NN), in clearance C8 (zero backlash) or C1 (low friction).

Part numbers & options
How a part number reads
CRBC 080 16 WW C8 P4 (thin type: CRBC 08008 WW C8 P0 L)
- CRBC
- Model code — CRBA split outer · CRBB split inner · CRBC high rigidity · CRBD/CRBE with mounting holes · CRBX custom
- 080
- Bore diameter — 080 = 80 mm (CRBC 20 to 400 mm; thin type 50 to 100 mm)
- 16
- Width (mm)
- (blank)
- Mounting holes — always blank on CRBC · 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
- P4
- Accuracy — P4 · P2 · PD4 · PD2 (thin type P0 only)
- L
- Thin type — L thin type · blank standard section
The configurator assembles this number for you, with drawings and 3D CAD. Configure ↗
Accuracy grades
The standard CRBC runs P4, P2, PD4 and PD2; PD grades hold tighter bore and outside diameter tolerances at the same runout. The thin type is graded P0 only.
- P4 High — Robot joints, rotary axes
- P2 Precision — Machine tools, inspection equipment
- PD4 High, tight diameters — P4 runout with tighter diameter tolerance
- PD2 Precision, tight diameters — P2 runout with the tightest diameter tolerance
- P0 Thin type — The single grade of the L series
Internal clearance
Clearance is set at the factory; pick it for the duty, not the size.
- 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

How buying works
Spec it in the configurator: drawings, 3D CAD, and a quote to follow.
HIWIN series are configured to your application, not bought off the shelf. Start from your loads and speeds if you are still choosing a size.
