Description
Overview:
The 6303 C3 Deep Groove Ball Bearing is a single-row, open-face bearing designed to reduce friction and support rotating shafts in machinery. Made from hardened bearing steel with precision-ground raceways and balls, it offers smooth, efficient operation under radial loads with capability for moderate axial loads. With dimensions of 17mm inner diameter, 47mm outer diameter, and 14mm width, it follows standard 6303 boundary sizes for easy replacement. The C3 internal clearance allows for reliable running at higher temperatures and speeds, making it a solid choice for electric motors, pumps, gearboxes, mower spindles, and compactors used in construction and garden equipment. Manufactured by NTN, a respected Japanese brand, this is a genuine part built for dependable service where regular re-lubrication is preferred.
