30309DDF TAPER ROLLER BEARING
- NTN tapered roller bearings are designed for the most demanding applications in industries such as mining, forestry and steel manufacturing.
- Utilizing conical rollers and raceways arranged so that the rollers and raceways meet at a common apex, NTN’s tapered roller bearing rollers are guided by contact between the large end of the roller, providing high capacity for radial and single thrust loads.
- With almost 100 million tapered roller bearings manufactured every year under the NTN and Bower brands, it’s no wonder that NTN rivals all major competitors on the market.
- The case carburization process creates a hardened steel “case” around the outside of the roller bearing while leaving a soft core.
- NTN’s pioneering efforts in developing crowned rollers have resulted in greater load-carrying capability and longer bearing life.
- NTN offers tapered roller bearings in ISO (metric), inch and J-metric series with single-row (cone/cup), two-row (back-to-back or face-to-face), double-row (double cup or double cone) and four-row assemblies available.
- NTN takes pride in selling locally manufactured tapered roller bearings to various markets.
- We offer premium tapered roller bearings under the NTN and Bower® brand names.
