By applying NSK's innovative concepts, the EM series bearing has a greater number of larger rollers than that of a conventional bearing. Furthermore, the optimally designed one-piece cage offers high rigidity and low-wear performance.

EW series bearing

Features:

1. Bearing life increased by twofold approximately
2. Noise and vibration levels reduced by 60-70%.
3. Cage strengthened by one and half to twofold.
4. Limiting speed upgraded by 10-25%.
