SKF spherical roller bearing C3 clearance (large clearance) Inner diameter 30 mm x outer diameter 72 mm x width 19 mm 21306 CC/C3 1 piece

Catalog number: 21306 CC/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 cracking 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, significantly extending the practical life of the bearing.
