Tapered Roller Set – Inch Series and J Series | L68149/L68111

L68149/L68111 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.
