SKF spherical roller bearing, inner diameter 45 mm x outer diameter 100 mm x width 25 mm, 21309 E, 1 piece

Catalog number: 21309 E Features: * The spherical roller bearing is a self-aligning type, and is less susceptible to shaft misalignment caused by shaft deflection, etc. * Special bainite material that is heat-resistant up to 200°C and has excellent resistance to wear, material cracking, and fatigue is used as standard. * Explorer specification model numbers have the following improved performance. * Compared to conventional design bearings, it has improved dynamic load capacity, improved wear resistance, reduced noise and vibration levels, and reduced frictional heat, significantly extending the practical life of the bearing.
