INA ZKLN5090-2Z-XL - Axial angular contact ball bearings ZKLN..-2Z, double direction, gap seals on both sides.
ZKLN5090-2Z-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.
