Description
Overview:
The 6306 C3 Deep Groove Ball Bearing is a single‐row, open‐type radial bearing engineered for smooth, low‐friction rotation in demanding machinery. This genuine NTN component is manufactured from high‐grade bearing steel for strength, wear resistance and long service life. The open face design allows straightforward inspection and re‐lubrication where required. With a 30 mm inner diameter (1.18 in), 72 mm outer diameter (2.83 in) and 19 mm width (0.75 in), it suits a wide range of equipment, including electric motors, pumps, compressors, gearboxes, conveyors and agricultural or garden machinery. C3 internal clearance supports reliable running at higher speeds and temperatures, making it a dependable choice for workshop repairs, plant maintenance and OEM replacements.
