Overview
Nachi 6306 ZZEC3 Deep groove ball bearing
Deep Groove Ball Bearing with shields on both sides and increased clearance
The Nachi 6306 ZZEC3 is a shielded deep groove ball bearing with a 30 mm bore, 72 mm outside diameter and 19 mm width. Non-rubbing steel shields on both sides hold the factory grease charge in place and keep coarse contamination out without adding drag, so the bearing runs nearly as fast and as cool as an open one while needing no relubrication. C3 clearance gives the ball set extra room for thermal growth, the cage is pressed sheet steel, and the sealed grease sets the working range at -40 to +120 degrees C. A practical sealed-for-life choice for motors and light industrial drives.
Key features
- Steel shields both sides retain grease, exclude dirt
- Non-contact shields add no measurable friction
- Increased C3 clearance for thermal expansion
- Greased for life, no relubrication needed
- Pressed sheet steel cage
- Operating range -40 to +120 degrees C
