INA needle roller bearings with TWin Cage

As INA bearing distributor, Nodes bearings have needle roller bearings with TWin Cage in stock, including NK30/20-TW, NKI35/20-TW, NKI40/30-TW, NKI55/25-TW.

INA needle roller bearings with TWin Cage comprise a plastic cage with two adjacent needle rollers per pocket and a machined outer ring.

The needle roller bearings are X-life bearings and have raceways with an optimised surface. This gives higher load carrying capacity and longer rating life.

In comparison with conventional needle roller bearings, the friction is reduced by up to 25%:

  • difference in frictional energy of up to 35 W at 4 000 min–1, compared with a standard bearing NK45/20-TV-XL
  • reduced heat generation
  • longer grease operating life and longer lubrication intervals
  • higher accuracy due to smaller temperature differences.
