The 25 mm steel shaft sleeve bearings 6005, 6205, and 6305 are deep groove ball bearings made from high-quality chrome steel (GCr15) designed for high-speed and long-life applications. The 6005 bearing measures 25 mm inner diameter, 47 mm outer diameter, and 12 mm width; the 6205 has a 25 mm bore, 52 mm outer diameter, and 15 mm width; the 6305 features a 25 mm bore, 62 mm outer diameter, and 17 mm width. These bearings support radial and axial loads, offering low friction and high precision, suitable for automotive, machinery, and agricultural equipment. They come in open, shielded (ZZ), or sealed (2RS) configurations for versatile use. Basic dynamic load ratings vary, with the 6305 rated around 20,600 N for durability under load.
