EW series NSK cylindrical roller bearings BENEFITS
- Up to 30% increase in load rating.
- Longer operating life – up to twice the bearing life.
- Cage strength is greater than major competitors.
- 10 - 25% higher limiting speed than conventional series.
- 30 - 40% noise reduction (3 - 7dB quieter) & vibration reduction.
NSK's newly developed cylindrical roller bearing, the EW series, which combines the strengths and technologies of previous cages into a one-piece steel cage. NSK has achieved a new design involving even newer concepts, while maintaining excellence in function and service life. NSK's EW series can meet your high load-carrying capacity needs for the new era.
