Overview
Nachi 6203 NR Deep groove ball bearing
Deep Groove Ball Bearing, open design with snap ring groove and circlip
The Nachi 6203 NR is a small deep groove ball bearing with a 17 mm bore, 40 mm outside diameter and 12 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.
