About the 6300 series
- Against the 6000 series, which shares thirty-one bore sizes, the 6000 outside diameter is smaller and the width smaller at each shared bore: at d 60 mm the 6312 is 130 × 31 mm and the 6012 is 95 × 18 mm.
- Against the 6200 series, which shares thirty-one bore sizes, the 6200 outside diameter is smaller and the width smaller at each shared bore: at d 60 mm the 6312 is 130 × 31 mm and the 6212 is 110 × 22 mm.
- Catalog dynamic load ratings Cr run from 7.38 kN (6300) to 278 kN (6332).
- Versions in the 6300 series: Open on every size, ZZ on twenty-nine of thirty-one sizes, 2RS on twenty-eight of thirty-one sizes, NR on twenty-six of thirty-one sizes.
Versions in this series
| Code | Meaning |
|---|---|
| Open | No shields or seals. Lubricated in service by grease or oil. |
| ZZ | Non-contact steel shields. Low friction; keeps out larger particles. |
| 2RS | Contact rubber seals. Better protection against dust and water; slightly higher friction. |
| NR | Snap ring on the outer ring for axial location in the housing. |
6300 series FAQ
Which sizes are in the 6300 series?
ENRO lists thirty-one sizes in the 6300 series, from the 6300 (10 × 35 × 11 mm) to the 6332 (160 × 340 × 68 mm). Bore d runs 10–160 mm.
Which versions are listed for the 6300 series?
Open, ZZ, 2RS and NR. Open: No shields or seals. Lubricated in service by grease or oil. ZZ: Non-contact steel shields. Low friction; keeps out larger particles. 2RS: Contact rubber seals. Better protection against dust and water; slightly higher friction. NR: Snap ring on the outer ring for axial location in the housing. Not every size carries every version; the model page lists what is available.
