TIMKEN double-row tapered roller bearings are units that combine two rows of tapered rollers in a single assembly, designed to support radial and axial loads in both directions. They are used in equipment where rotational precision and rigidity are critical, such as gearboxes, spindles and process machinery. At MR Accesorios Industriales we quote them by part number or designation.
The designation of this line starts with the letter M followed by a number that identifies the size and geometry of the assembly; the XS suffix corresponds to the 2TS-IM series, which is the double-row variant with assembled cone and cup. For example, M205149XS, M207049XS or M249749XS share that logic: the initial M, the numeric block and the XS ending. With the complete part number we quote the exact reference or its compatible equivalent.
These bearings are chosen for applications where combined loads must be absorbed and the shaft kept aligned with minimal clearance. In Argentina you will find them in speed reducers, conveyor belts, mills, presses and material handling equipment. They also appear in machine tool spindles and rolling mill rolls, where axial rigidity defines process quality. They are a robust solution for continuous service and dusty or vibrating environments.
To select the correct assembly, take into account the radial and axial load it will support, the rotational speed and the intended type of lubrication. Mounting requires cleanliness, alignment of both rows and an axial adjustment that guarantees the recommended internal clearance; excessive preload accelerates wear. If the equipment operates with contaminants, additional sealing or oil seals should be evaluated. Lubrication must be suitable for the temperature and load, and must be checked at every maintenance interval.
Regarding equivalences, double-row tapered roller bearings are identified by their designation and by their main dimensions. When requesting a quote, the safest approach is to provide the complete part number shown on the equipment or on the reducer nameplate. If you do not have it at hand, we can help you identify it using the shaft and housing dimensions. We work with leading brands and indicate the compatible alternative when the original reference is not available.
MR Accesorios Industriales has been selling TIMKEN bearings and other power transmission lines for more than 80 years. If you need this type of bearing, send us the part number via WhatsApp and we will quote it promptly. We can also advise you on mounting and lubrication so that the assembly works under the intended conditions.

Frequently Asked Questions
- What does the XS suffix mean on these TIMKEN bearings?
- The XS suffix identifies the 2TS-IM series, which corresponds to a double-row tapered roller bearing with assembled cone and cup. It is a TIMKEN designation for this configuration. If your equipment uses a reference with XS, send us the complete part number and we will quote the equivalent.
- How do I choose the correct double-row bearing for my equipment?
- You need to know the radial and axial load, the rotational speed and the type of lubrication. The shaft and housing dimensions also matter. With that data we indicate the appropriate TIMKEN reference or a compatible alternative. If you have the original part number, even better: we quote it directly.
- Do you ship nationwide?
- Yes, we ship nationwide. We coordinate shipping via WhatsApp once you confirm the quote. You can also pick up at our facilities in Buenos Aires, Argentina. Ask us about the logistics that suit you best.
