INA ZKLF2068-2RS-XL - Axial angular contact ball bearings ZKLF..-2RS, double direction, for screw mounting, lip seals on both sides.
ZKLF2068-2RS-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.
