Overview
Nachi 6312-2NSEC3 Deep groove ball bearing
Deep Groove Ball Bearing with contact seals on both sides and increased clearance
The Nachi 6312 -2NSEC3 pairs a 60 mm bore with a 130 mm outside diameter and 31 mm width. Rubber contact seals ride on the inner ring land at both sides, giving a far tighter barrier against water, dust and washdown than a shield can manage, at the cost of a little more running torque. The grease is sealed in for the life of the bearing. C3 clearance offsets the fit-up and thermal losses that would otherwise leave the bearing preloaded, the cage is sheet steel, and the assembly is rated from -20 to +130 degrees C. Well suited to dirty or damp duty where relubrication is impractical.
Key features
- Contact seals both sides for wet and dusty duty
- Sealed grease fill, maintenance free
- Increased C3 clearance for thermal expansion
- Strong protection against washdown and airborne dirt
- Pressed sheet steel cage
- Operating range -20 to +130 degrees C
