SKF spherical roller bearing, inner diameter 90 mm x outer diameter 190 mm x width 43 mm, 21318 E, 1 piece

Catalog number: 21318 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, resulting in a significant extension of the bearing's practical lifespan.
