INA NK6/12-TN-XL bearing


Wear will degenerate the close tolerances normally held in the bearing and can lead to other problems. Much closer to pure rolling can be achieved in a tapered roller bearing and this avoids rapid wear. The rollers are guided by a flange on the inner ring. This stops the rollers from sliding out at high speed due to their momentum.
