INA ZARN3080-TV - Needle roller/axial cylindrical roller bearings ZARN, double direction.
ZARN3080-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.
