SKF spherical roller bearing, inner diameter 50 mm x outer diameter 110 mm x width 27 mm, 21310 E, 1 piece

Catalog number: 21310 E 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 with excellent wear resistance, material crack resistance, and fatigue resistance 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.
