Needle roller/axial cylindrical roller bearings (With fixing holes Without fixing holes)
Features
Needle roller/axial cylindrical roller bearings 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 with or without fixing holes.
Radial and axial load carrying capacity
In addition to radial forces, the bearings can also support axial forces from both directions and tilting moments.
Preload and internal clearance
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 theprecision locknut. The radial internal clearance conforms to Group 2 in accordance with ISO 5753-1 .
Bearings for screw mounting
Needle roller/axial cylindrical roller bearings ZARF(L) have holes in the outer ring. These are used for screw mounting directly on the adjacent construction or in a radial locating bore Figure 1.
Due to screw mounting of the outer ring, the cover that would otherwise be required and the matching work can therefore be dispensed with. The bearings are preloaded against the shaft shoulder by means of a locknut AM or ZM(A).
