NTN 3920-TRB Tapered Roller Bearing

NTN 3920-TRB is a tapered roller bearing from NTN, identified by the catalog designation 3920-TRB. Tapered roller bearings are designed to support combined radial and axial loads in rotating equipment, providing stiffness and durability through load distribution along the bearing assembly. The 3920-TRB entry denotes a specific size and tolerance class within NTN’s tapered bearing family, intended for assemblies where reliable load carrying and smooth rotation are essential. This bearing is suitable for use in machinery requiring precise alignment and long service life under rotating service conditions. The 3920-TRB is manufactured to NTN's specifications for tapered bearings, with emphasis on consistent clearance and load distribution across the rollers when correctly installed and lubricated. Exact fitment depends on mating components and housing, but the NTN 3920-TRB represents a standard option within the tapered bearing category for applications needing robust radial-thrust support.
