NTN Tapered Roller Bearings (TRBs) are designed for the most demanding applications in industries such as mining, forestry and steelmaking. With almost 100 million tapered roller bearings manufactured every year under NTN and Bower brands, it’s no wonder that NTN TRBs rival all major competitors on the market.

Heat treated based on application needs, case carburization creates a hardened steel “case” around the outside of the bearing, while leaving a soft core, providing excellent heavy shock-load capabilities. Case carburization also delivers greatly increased component durability and extended life, resulting in increased maintenance intervals and reduced downtime.

 

Tapered Roller Bearings

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.

 

 

 

2-Row Tapered Roller Thrust Bearings

Optimized internal geometry to ensure the highest load capacity is achieved to support high thrust loads in both work rolls and back up rolls.

 

 

 

4-Row Tapered Roller Bearings

Made with a wide variety of features to keep contaminants out and lubrication in that include RustGuard® and engineered face seals to displace moisture and prevent rust and corrosion.

 

 

 

4-Row Cylindrical Roller Bearings

Made from the cleanest steel that is treated and formed with the highest quality processes, including options like case carburized, carbonitriding and/ or phosphate coating for superior mill performance.
