INA ZKLF2068-2RS-2AP-XL Axial Angular Contact Ball Bearing is a precision bearing for screw drives and spindle support positions requiring accurate axial location and high rigidity. It provides low friction and repeatable positioning in ball screws, lead screws, and machine tool feed axes.
The design uses balls with a large contact angle, precision raceways, and controlled preload. Flanged or cylindrical outer-ring styles such as ZKLF and ZKLN can be selected according to the mounting interface.
Select by screw shaft diameter, preload, precision class, flange requirement, speed, and target positioning accuracy.
