INA ZKLN2557-2RS-XL - Axial angular contact ball bearing ZKLN..-2RS-XL, double direction, no screw mounting.
ZKLN2557-2RS-XL INA angular contact ball bearings is in the X-life design. As a result of increased raceway accuracy and raceway quality, there is a significant reduction in the stress conditions present on the rolling elements and raceways under the same load, compared to the standard bearings.
