Bower JHM720249 Round Bore Tapered Roller Bearing

Bower JHM720249 is the inner cone (bearing race) of a metric, round-bore tapered roller bearing in the J-series. It is designed to mate with the JHM720210 cup to form a TS (tapered single) matched bearing assembly. The cone features a 100 mm bore, a 155 mm outer diameter, and a 41 mm width, with a maximum shaft fillet radius of 3 mm for proper fit on compatible shafts. The dynamic load rating is 415,000 N, supporting high-load, high-speed operation in wheel-end hubs and other machinery that use round-bore tapered bearings. When paired as JHM720249/JHM720210, the set provides the correct preload and geometry for reliable rotation in automotive and industrial applications that require metric round-bore taper bearings. Bower-branded and aligned with Timken’s J-series design, this cone is intended to be used with the matching cup to complete a full bearing assembly, rather than as a standalone component.
