Thin universal washers for needle roller thrust bearings are supplied as separate components. They are made of spring steel and hardened, and both faces of the washers are polished and can be used as raceways. The washers can provide cost-effective solutions, if the adjacent machine components are not hardened, but have adequate stiffness, and the requirements to run-out are moderate. They can be used as shaft or housing washers for AXK series bearings, and as shaft washers for AXW series bearings.
Enable full interchangeability of washers
Require minimal axial space
Provide cost-effective solutions
AXK1226 Needle roller and cage thrust assemblies are designed to accommodate heavy axial loads and peak loads in one direction. They provide a high degree of stiffness within a minimum axial space. In applications where the faces of adjacent machine components serve as raceways, needle roller thrust bearings take up no more space than a conventional thrust washer. The bearings can also be combined with bearing washers to create complete bearings.High axial load carrying capacity
High stiffness
Long service life

Drawn Cup Needle Roller Bearings have a deep drawn, thin-walled outer ring. Drawn cup needle roller bearings are typically used in applications where the housing bore cannot be used as a raceway for a needle roller and cage assembly, but where a very compact and economical bearing arrangement is required. These bearings are mounted with a tight interference fit in the housing. That enables a simple and economic design of the housing bore, as shoulders or snap rings are not required to locate the bearing axially.
The drawn cup of hardened steel and the needle roller and cage assembly of these bearings form a non-separable unit.
TKW supplies a wide assortment of drawn cup needle roller bearings. This includes:
-- Bearings with open ends
-- Bearings with a closed end
-- Full complement bearings with open ends
TKW drawn cup needle roller bearings:
-- are supplied without an inner ring
-- are generally designed with one needle roller and cage assembly -- except wide sizes, which incorporate two needle roller and cage assemblies immediately adjacent to each other, with a lubrication hole in the outer ring
· Drawn cup needle roller bearings with open ends
o are available open (without seals) or sealed on one or both sides
· Drawn cup needle roller bearings with a closed end
o are available open or sealed
o are suitable for bearing arrangements where they are situated at the end of a shaft
o accommodate small axial guidance forces, because of the profiled design of their closed end
· Full complement bearings with open ends
o are suitable for very heavy radial loads at moderate speeds
o are available with open ends and without seals only
Full complement drawn cup needle roller bearings are supplied with a special grease to secure the rollers during transport. However, TKW recommends relubricating after mounting.
In order to support axial forces, the bearings can be combined with axial bearings.
