NTN Bearing 3720 Tapered Roller Bearing Single Cup American-Made Case Carburized Steel 3.6718" OD 0.9375" Width

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. NTN offers premium tapered roller bearings under the NTN and Bower brand names featuring 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. NTN-Bower Corporation is one of the largest manufacturers of precision roller bearings in North America with a primary focus on serving the transportation, construction, and agricultural implement markets.
