When a shaft has to carry radial and axial forces at the same time, a double-row tapered roller bearing is often the answer. TIMKEN builds these as matched assemblies with two rows of tapered rollers in one unit, and the HM series is a common choice for gearboxes, spindles and heavy machinery. MR Industrial Accessories supplies this line to maintenance and purchasing teams across the US and Latin America.

Reading the code helps you order the right piece. Take HM231110ES: the HM prefix sets the dimension series, the middle digits 231110 set the size inside that series, and the ES suffix tells you it is a double-row layout with a defined cone and cup arrangement. Related arrangements in the same family carry designations such as 2TS-IM, 2TS-DM and SR.

These bearings show up where motion is heavy and precision matters: mill gearboxes, presses, cranes, conveyors, construction machinery, machine tool spindles and rolling mill rolls. The double row takes combined loads while holding alignment, so they also suit shafts that bend, like those driving belts or chains in continuous process plants.

Selection comes down to three things: which direction the load mostly pushes, how much vibration the application allows, and how the bearing will be lubricated. Grease or oil both work, depending on speed and operating temperature. Because the double row is stiffer than a single arrangement, mounting needs care: check housing alignment and axial fit, and confirm the seal keeps contaminants out. Incorrect tightness at mounting shortens service life, so follow the manufacturer's recommendations for the specific series.

On equivalents, every maker uses its own full designation, and no universal cross-reference exists. A workable alternative can be found by matching dimensions, load capacity and configuration. MR Industrial Accessories can help you locate the right replacement among the brands it carries, starting from your original part number or the mounting dimensions.
