The INA ZKLF40115-2RS-PE axial angular contact ball bearing unit is a super-precision bearing assembly designed specifically for screw drive and high-accuracy positioning applications. Manufactured by Schaeffler under the INA brand, the bearing features a double-row axial angular contact ball arrangement capable of supporting high axial loads in both directions while maintaining exceptional rigidity and running accuracy. The integrated lip seals on both sides provide reliable protection against contaminants and lubricant loss, ensuring long service life and low maintenance operation. The bearing unit incorporates a thick-walled outer ring with mounting holes for direct screw mounting, simplifying installation and improving structural rigidity. Designed for CNC machinery, ball screw assemblies, servo systems, automation equipment, and precision machine tools, the ZKLF40115-2RS-PE delivers excellent stiffness, low friction, and precise motion control performance.
