Overview
Nachi 6310-2NSE9C4 Deep groove ball bearing
Deep Groove Ball Bearing with contact seals on both sides and strongly increased C4 clearance
The Nachi 6310 -2NSE9C4 is a sealed deep groove ball bearing of 50 mm bore, 110 mm outside diameter and 27 mm width, supplied with C4 clearance. C4 goes a step beyond C3 and is specified where the inner ring runs much hotter than the housing or where both rings are fitted with interference, either of which would leave a standard bearing preloaded. Contact seals on both sides keep the grease in and the dirt out. Pressed sheet steel cage, rated -20 to +130 degrees C.
Key features
- Strongly increased C4 radial internal clearance
- Contact seals both sides, sealed for life
- For large temperature differentials across the bearing
- Suits interference fits on both rings
- Pressed sheet steel cage
- Operating range -20 to +130 degrees C
