Overview
Nachi 6309 NR Deep groove ball bearing
Deep Groove Ball Bearing, open design with snap ring groove and circlip
The Nachi 6309 NR is a medium-sized deep groove ball bearing with a 45 mm bore, 100 mm outside diameter and 25 mm width, machined with an annular groove in the outer ring and supplied with the matching circlip. The snap ring locates the bearing axially against a plain housing bore, which removes the need for a shoulder or end cap and shortens the housing considerably. The bearing is open on both sides, guided by a pressed sheet steel cage, set to normal CN clearance and rated -20 to +150 degrees C.

- Locates axially in a plain housing bore
