The NTN 423140 is a double row tapered roller bearing in through hardened steel. It has a 200 mm bore (ID), a 340 mm outside diameter (OD), a 140 mm cone width and a 112 mm cup width, with a dynamic load rating of 1,090,000 N.
The rollers are tapered and touch the races along a line, so the bearing carries combined radial and axial load, and two rows in one unit let it take axial thrust from either direction. Bearings of this type turn up in axles, differentials, propeller shafts and gearboxes. Running clearance and preload depend on how the cone sits against the cup at assembly.
