Drawn cup Needle Roller Bearings

UKL 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.

Needle roller bearings with machined rings, with an inner ring

UKL needle roller bearings with machined rings are made of carbon chromium bearing steel. UKL supplies these bearings with or without flanges on the outer ring, in a wide range of series and sizes. UKL also supplies them with or without an inner ring.

Alignment needle roller bearings

UKL alignment needle roller bearings have an outer ring with a sphered (convex) outside surface. Two polymer seating rings with asphered (concave) inside surface are encased in a drawn sheet steel sleeve and fitted over the outer ring.

Combined needle roller bearings

UKL combined needle roller bearings consist of a radial needle roller bearing combined with a thrust bearing. They can accommodate both radial and axial loads. They are particularly suitable for applications where other types of locating bearing arrangements occupy too much space, or where the axial loads are too heavy, the speeds are too high, or the lubricant is inadequate for arrangements with simple thrust washers.

UKL supplies combined needle roller bearings in three basic designs:

* Needle roller / angular contact ball bearings

* Needle roller / thrust ball bearings

* Needle roller / cylindrical roller thrust bearings

Needle roller bearing components

UKL supplies both inner rings for needle roller bearings and needle rollers as separate needle roller bearing components.
Inner rings are typically combined with needle roller and cage assemblies or drawn cup needle roller bearings in applications where the shaft cannot be hardened and ground.
Needle rollers can be used to design full complement bearing arrangements for low-speed or oscillating applications. These compact bearing arrangements have a very high load carrying capacity when compared to bearings with a cage and are economical, provided the shaft and housing bore can serve as raceways (Raceways on shafts and in housings).
