Overview
Nachi 1208 KC3 Self-aligning ball bearing
Self-Aligning Ball Bearing with tapered bore and increased clearance
The Nachi 1208 KC3 is a double-row self-aligning ball bearing measuring 40 mm bore by 80 mm outside diameter by 18 mm width, on a 1:12 tapered bore. The taper lets the bearing be mounted with an adapter sleeve on a plain shaft, so it can be positioned anywhere along an unmachined length rather than needing a turned and ground seat, which is why this combination dominates line shafting and conveyor drives. C3 starting clearance allows for the reduction that occurs as the bearing is drawn up the taper. Self-aligning, sheet steel cage, rated -30 to +150 degrees C.
Key features
- Tapered 1:12 bore for adapter sleeve mounting
- Mounts anywhere on a plain, unmachined shaft
- Increased C3 clearance before mounting
- Self-aligning under misalignment and deflection
- Sheet steel cage, very low friction
- Operating range -30 to +150 degrees C
