Outer Ring Type: Flat

IKO Machined Type Needle Roller Bearings have an outer ring made by machining, heat treatment, and grinding. The outer ring has stable high rigidity and can be easily used even for light alloy housings.

These bearings are available in metric series and inch series, both of which have the caged type and the full complement type. It is therefore possible to select a suitable bearing for use under various conditions such as heavy loads and high-speed or low-speed rotations. In addition, there are bearings with and without an inner ring. As the type without inner ring uses a shaft as the raceway surface, a compact design is possible.

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.
