unlike other roller bearings, needle bearings may have only an outer ring. when the inner ring is omitted (and the inner race along with it), the shaft that the needle roller bearing rotates around serves as the inner race. needle roller bearings have more surface area in contact with the races (or the race and the shaft) compared to ball
needle roller and cage assemblies are single or double row units comprising cages and needle rollers. as their radial design height only corresponds with the diameter of the needle rollers, needle roller and cage assemblies can be used to realize bearings with a minimal radial design envelope.
the needles in these bearings roll freely in one direction, but lock to transmit torque when the rotation of the shaft is reversed. also known as drawn cup roller clutches. an arrow on the lip indicates the rotational direction that locks the bearings.. single row bearings do not support loads from any direction. to support radial loads, use with our needle roller bearings.

of type na's (outer ring, needle rollers and cage) are non separated, but inner ring can be parted from outer assembly. when needle rollers bearings are without an inner ring, its rollers would have direct contact with shaft surface. in this way, the hardness and dimension of journal must reach the requirements of bearing raceway. type nav, rnav
