The TIMKEN TDO series is a double row tapered roller bearing built as two opposed rows, so it takes radial and axial loads in both directions. You will find it in gearboxes, drive shafts and mining equipment where high load capacity and rigidity are required. MR Industrial Accessories LLC supplies this line as part of its bearings and power transmission range for customers in the United States and several Latin American countries.

Reading a TDO code helps you identify what you are ordering. Letters and numbers in the designation point to size and internal design: the prefix HM marks a specific dimensional family, X signals variations in the cone and cup, and D confirms the double row assembly. Take HM120817XD: it is a double row tapered bearing of the HM series, and the XD suffix defines its configuration. If you need help decoding a designation, send it to our team.

These bearings show up in speed reducers, gearboxes, rolling mill roll shafts, crushing and grinding equipment, and machinery for cement and mining. Railway applications and earthmoving equipment also use them, since combined loads and tilting moments call for a robust arrangement. Because they support loads in both directions, they work in fixed and floating positions.

Selection depends on the radial and axial load, the rotational speed and the environment. Sealing and lubrication matter: in dusty or humid conditions, use suitable seals and high-viscosity grease. Shaft-to-housing alignment must be precise to avoid extra stresses. Mounting calls for a press or controlled heating, and the internal clearance has to be correct for the assembly to reach its service life.

TDO series bearings can be interchanged with other brands that offer equivalent double row configurations, provided dimensions and load capacities match. Always check tolerances and the cone and cup design before substituting. Our team can help you find a compatible alternative that keeps your application running.
