TSUBAKI NAKASHIMA
Tsubaki Nakashima Tapered Rollers
Manufacturer: TSUBAKI NAKASHIMA CO., LTD.
Features
- As the world’s largest independent producer of tapered rollers, We manufactures rollers in a range of sizes, materials and profiles according to customer specification.
- Tapered rollers, typically found in automotive, wind, rail and industrial applications, carry both radial and axial loads and can carry higher loads than ball bearings due to the line contact between the roller and raceway.
Main Markets
- Automotive
- Wind
- Rail
