Deep Groove Ball Bearing with a shield on one side and increased clearance
Nachi's 6309 ZEC3 has a 45 mm bore, 100 mm outside diameter and 25 mm width, with a pressed steel shield fitted to one side. The shielded face keeps grease in and dirt out where the bearing is exposed, and the open face lets lubricant reach the ball set from the housing side. C3 clearance leaves headroom for thermal growth and tight shaft fits. Pressed sheet steel cage, operating range -40 to +120 degrees C.
