Background Information
- Industry: Paper
- Country: US
- Application: calendar Roll
- NSK Product: TL Spherical
- Approx life: 30 days
- 12 failures annual
Value Proposals
- NSK investigated the failed competitors bearings
- Application review was conducted by NSK engineers
- It was determined that the high heat in the application was causing the bearings inner rings to crack
Product Features
- Innovative chemical steel composition
- Special heat treatment process
- High stregth inner and outer rings
- Heat resistant to cracks
- Greater resistance to hoop stress
- Longer service life- more than twice that of conventional bearings operation under contaminated conditions
- Greater dimensional stability under high temperatures ( to 200O C).
