Combined Needle Roller Bearing ZARN 2557 TN Thrust needle roller bearing
Needle roller bearing /cam follower is composed of a stud used as the tray of a group of rollers and a thick wall outer ring .The shoulder of the stud and the surface retaining ring on the stud form the guiding faces on the two sides of the outer ring.When the curve rollers are running on the plain tray or cam wheel,the inner stress on the rollers will increase due to the deformation of the outer ring.
Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing
Ball Screw Bearing ZARN70130-TV 70X130X82mm Combined Cylindrical Needle Roller Bearing ZARN 70130 comprise an outer ring with radial and axial raceways, shaft locating washers, an inner ring, a radial needle roller and cage assembly and axial cylindrical roller and cage assemblies. The bearings are available in versions for screw mounting and not for screw mounting.The outer ring, inner ring and axial cages are matched to each other such that the bearing is axially clearance-free after preloading by means of an precision locknut. The radial internal clearance is C2 according to DIN 620.
