1020 Bearing Product Overview & Core Advantages
The 1020 metric thrust ball bearing is engineered for pure axial load applications requiring high precision and reliability. This open-type bearing features 52100 Chrome Steel construction throughout its rings and balls, delivering exceptional durability under demanding conditions. With its high axial dynamic load capacity of 4495 lbf and precise dimensional tolerances, this bearing provides stable performance in applications where accurate axial positioning is critical. The compact design with 100mm bore diameter and 25mm width makes it ideal for space-constrained installations.
