Tapered roller bearings utilize conical rollers and raceways, arranged so that the rollers and raceways meet at a common apex. The rollers are guided by contact between the large end of the roller and a rib on the inner ring. This provides high capacity for radial and single thrust loads.
We offer premium tapered roller bearings under the NTN and Bower® brand names. Most NTN and all Bower® tapered roller bearings feature case-carburized components. Cups, cones, and rollers are made from case-hardened alloy steel of “Bearing Quality” to provide superior fatigue life and reliability. Precise control of heat treatment, dimensions, and surface finish of the components further contribute to reliable bearing performance. So whether you’re looking for an American-made, case-carburized inch series taper, or a metric series through-hardened variety, we have you covered with a proper fit for your application. Premium steels and heat treatments are also available for applications requiring extended life and high reliability.
NTN’s pioneering efforts in developing crowned rollers have resulted in greater load-carrying capability and longer bearing life. Crowned rollers under load distribute stress equally along their full length of contact with the raceways, thereby eliminating stress concentration at the roller ends. This design concept also compensates for minor misalignment between shaft and housing bore and deflection under load, thereby reducing stress concentration.
NTN's Top TRB Stock Guarantee Program is the only guaranteed inventory stocking program in the industry, and is available exclusively to NTN distribution partners.

Industrial Tapered Roller Bearings can carry combinations of large radial and thrust loads. The Industrial Tapered Roller Bearings are used in the construction machinery, gear, construction, and vehicle manufacture. We offers our clients with a wide range of Industrial Tapered Roller Bearings. We also offer Industrial Tapered Roller Bearings in customized specifications as per the clients’ requirements.
Double row tapered roller bearings are used where load carrying capacity should be greater, loads should be taken in both directions and axial space is smaller than in case of a set of two single row tapered roller bearings.
