About the 6400 series
- Against the 6800 series, which shares twenty-two bore sizes, the 6800 outside diameter is smaller and the width smaller at each shared bore: at d 70 mm the 6414 is 180 × 42 mm and the 6814 is 90 × 10 mm.
- Against the 6900 series, which shares twenty-two bore sizes, the 6900 outside diameter is smaller and the width smaller at each shared bore: at d 70 mm the 6414 is 180 × 42 mm and the 6914 is 100 × 16 mm.
- Catalog dynamic load ratings Cr run from 22.70 kN (6403) to 300.00 kN (6426).
- Versions in the 6400 series: Open on every size, 2RS on three of twenty-two sizes, ZZ on two of twenty-two sizes.
Versions in this series
| Code | Meaning |
|---|---|
| Open | No shields or seals. Lubricated in service by grease or oil. |
