Overview
Nachi 6303-2NKE9C3 Deep groove ball bearing
Deep Groove Ball Bearing with non-contact seals on both sides and increased clearance
The Nachi 6303 -2NKE9C3 has a 17 mm bore, 47 mm outside diameter and 14 mm width, with non-contact seals fitted to both sides. Running in a close labyrinth gap rather than against the inner ring, they retain grease and turn dirt away while leaving friction and heat essentially unchanged from an open bearing. C3 clearance covers thermal growth and press fits. Pressed sheet steel cage, rated -20 to +120 degrees C.
Key features
- Non-contact seals both sides, no rubbing contact
- Increased C3 clearance for thermal expansion
- Speed capability close to an open bearing
- Grease retained without added drag
- Pressed sheet steel cage
- Operating range -20 to +120 degrees C
