TIMKEN double row tapered roller bearings are assemblies that combine two rows of tapered rollers in a single mounting. They are used to support radial and axial loads in both directions, with high load capacity and rigidity. They are common in applications requiring robust, compact support, such as gearboxes, machine tool spindles and mining equipment. At MR Accesorios Industriales we quote them with the part number you provide.

The designation of this family is read by series and its suffixes. For example, LM119311D, LM119348D and LM241110D share the LM prefix and the D suffix, which in the TIMKEN catalogue identifies double row assemblies. The TDO, TDI or TNASWE series indicates the mounting configuration: two cones, two cups or a combination of both. With the complete part number we can identify the exact reference and quote it.

These bearings are used in industries such as mining, cement, steel and food. In Argentina we find them in speed reducers, mills, conveyor belts, presses and earthmoving equipment. Their double row allows replacing two single row bearings in a smaller space, simplifying shaft design and reducing the number of mounting components.

To select the correct bearing, consider radial and axial load, rotational speed and environmental conditions. Sealing is key: in dusty or humid environments additional protection is recommended. Lubrication must be adequate and mounting requires precise alignment and a fit that guarantees the correct internal clearance. Incorrect mounting can reduce bearing service life.

TIMKEN tapered roller bearings are interchangeable with those of other brands as long as the main dimensions and contact angle match. Each manufacturer has its own nomenclature, so equivalence is established by comparing dimensions and load capacities. If you need to replace a reference, write to us with the original part number and we will indicate the compatible alternative.

At MR Accesorios Industriales we sell the TIMKEN line of double row tapered roller bearings. If you are looking for an LM series reference with a D suffix, send us the part number on WhatsApp and we will quote it shortly. We can also advise you on mounting and lubrication so the bearing works under the right conditions.
