Detailed Photos

Our 30308 with flange and 32309 with flange are high-precision single-row tapered roller bearings designed with a flanged outer ring for easy axial positioning and installation. Made of premium GCr15 chrome steel, they offer high hardness, wear resistance, and excellent performance under heavy combined radial and axial loads. The 30308 with flange (40×90×25.25mm) delivers a dynamic load rating of 91 kN and a static load rating of 102 kN, while the larger 32309 with flange (45×100×38.25mm) provides even higher capacity with 144 kN dynamic and 187 kN static load ratings. Both feature separable cone and cup designs for simplified assembly, low noise, low vibration, and long service life, making them ideal for use in automotive wheel hubs, transmissions, construction machinery, agricultural equipment, and industrial gearboxes. They are available in P0/P6/P5 precision grades with steel cages, and can be packaged in neutral export cartons or customized with OEM labels according to your requirements.
