SKF spherical roller bearing C3 clearance (large clearance) Inner diameter 40mm x Outer diameter 90mm x Width 23mm 21308 E/C3 1 piece

Catalog number: 21308 E/C3 Features: * The spherical roller bearing is a self-aligning type, and is less susceptible to shaft misalignment caused by shaft deflection, etc. * Special 200°C heat-resistant bainite material is used as standard, which has excellent wear resistance, material crack resistance, and fatigue resistance. * 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, resulting in a significant extension of the bearing's practical lifespan.
