Drawn Cup Needle Roller Bearings
The low cross section of the drawn cup bearing provides maximum load-carrying capability with minimum space required. Available in 3 mm to 139.7 mm bore (1/8 to 5 1/2 in).

Radial Needle Roller And Cage Assembly
With no inner or outer ring, the low cross section provides maximum load-carrying capability within the smallest envelope. Available in 3 mm to 165 mm bore (1/8 to 6 1/2 in).

Heavy Duty Needle Roller Bearings
Available in 5 mm to 335 mm bore (3/16 to 13 3/16 in), consist of a machined and ground channel-shaped outer ring with a complement of needle rollers retained and guided by a cage.

Thrust Needle Roller Bearings
The purpose of these assemblies is to transmit a thrust load between two relatively rotating objects while greatly reducing friction.

Combined Needle Roller Bearings
Combined bearings consist of a radial bearing (needle roller bearing) and a thrust bearing (ball or roller bearing). Some combined bearings are constructed similar to drawn cups, but with an added thrust bearing component.

Inner Rings
Inner rings are made of rolling bearing steel and after hardening, their bores, raceways and end surfaces are ground.
