Product Description:

Entity by a needle bearing ring or two rings and a cage with needle rollers. According to different applications, can be divided into the bearings with inner ring or inner ring.Therefore, the physical ring needle roller bearings can meet the requirements of light weight, small space occupation, large transmission power requirements. Size and higher carrying capacity physical ring needle roller bearings with smaller.

The main structures

Outer double wall (or double lock ring) with cage of needle roller bearings NA, NKI type

The inner and outer rings can be installed separately (with a lock ring, a full set of needle roller and cage), access high speed, divided into single and double row two.

If the shaft can not be used as a raceway, hardened shaft that if grinding is not possible orthe economy, you can use these needle roller bearings with inner ring.

There is no inner needle bearing cage

NA, NKI type bearings without inner ring is RNA, NK type needle roller bearings.

Such bearings without inner ring, radial mounting dimensions for the supporting structurerestricted, and the match of the journal bearing is directly used as a rolling surface. As a raceway shaft, and grinding the hardware must be quenched, and only be processed to the appropriate size and shape accuracy, service life and operation precision set of needle roller bearings to higher. At the same time, because of the inner ring, the diameter of the shaft may also be appropriate to increase, thus increasing the rigidity.

Sealed needle roller bearings with or without inner ring

Needle roller bearings, single or double seal can effectively prevent the intrusion of dirt,bearing in lithium base grease amount. This type of bearing inner ring outer ring width than, and ensure a good seal and prevent injury to the bearing pollution can also which makes the bearing have micro displacement in the shaft to the bearing box. The inner ring of the bearing has the lubrication oil hole, can be configured according to the needs, from the outer ring or inner added lubricating.
