Description
Overview:
The 6203 C3 Deep Groove Ball Bearing is a high-quality, open-type single-row bearing for general-purpose use across industrial, automotive, and garden machinery. Made from hardened bearing steel with precision-ground raceways, it supports primarily radial loads with capability for light axial loads in both directions, helping reduce friction and wear on rotating shafts. This genuine NTN component (MPN: NTN6203C3), manufactured in Japan, offers dependable performance in electric motors, pumps, alternators, and compact machinery. Dimensions are 17mm inner diameter, 40mm outer diameter, and 12mm width. The open face design suits applications where routine lubrication and visual inspection are preferred. With C3 internal clearance, it accommodates thermal expansion and higher running speeds, helping maintain smooth, efficient rotation under varying operating conditions.
