INA ZARF2575-L-TV - Needle roller/axial cylindrical roller bearings ZARF..-L, double direction, for screw mounting, long shaft locating washer.
ZARF2575-L-TV INA axial/radial roller bearings for screw drives are double direction, high precision axial cylindrical roller bearings with a radial bearing component. The inner ring, outer ring and cylindrical roller and cage assemblies are matched to each other such that the bearing is axially clearance-free after preloading by means of an INA precision locknut.
ZARF2575-L-TV INA is with fixing holes in the outer ring, which is screw mounted directly on the adjacent construction. ZARF2575-L-TV have a stepped shaft locating washer extended on one side.
