TIMKEN SR series double-row tapered roller bearings are components designed to support radial and axial loads in both directions. Their construction with two rows of tapered rollers handles combined forces with high rigidity, making them suitable for demanding applications. They are used in industrial machinery, transmission equipment and assemblies where precision and durability are required. At MR Accesorios Industriales we quote them according to the part number you need.
The designation of these bearings combines letters and numbers that identify the series and the size. In the SR series, part numbers such as LM104948XS or LM506849XS begin with the letters LM, which indicate the double-row tapered roller family. The following digits define the dimensions and the internal design, while the XS suffix indicates a specific construction variant. Knowing these part numbers makes identification easier when requesting a quote or a replacement.
These bearings are used in industries such as metallurgy, cement, mining and food processing, in equipment such as conveyor belts, mills, presses and gearboxes. In Argentina, they are common in production plants and maintenance workshops looking for reliable spare parts for heavy machinery. Their ability to support combined loads makes them suitable for transmission shafts and high-demand rollers.
To select the correct bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. Sealing and lubrication are critical: choose the type of sealing according to contamination and working temperature. Shaft alignment and internal clearance must be verified during mounting to avoid premature failures. Mounting with suitable tools and rigorous cleanliness extends the service life of the component.
When looking for equivalents, it is important to compare not only the main dimensions but also the load capacity and the internal design. Different manufacturers may use their own nomenclature, so interchangeability must be technically validated. At MR Accesorios Industriales we indicate the compatible alternative or manufacture it to measure if necessary, always backed by more than 80 years in the market.

Frequently Asked Questions
- What does the XS suffix mean in TIMKEN SR series bearings?
- The XS suffix indicates a construction variant within the SR series, which may include specific internal design or sealing features. To correctly interpret the full part number, it is advisable to consult a specialist who can validate the application.
- How do I choose between a double-row and a single-row bearing?
- The choice depends on the loads and the required rigidity. Double-row bearings support axial loads in both directions and offer greater load capacity, while single-row bearings are used when loads are mainly radial or in a single direction.
- What should I take into account when mounting a tapered roller bearing?
- Verify shaft alignment, internal clearance and proper lubrication. Use mounting tools that do not damage the raceways and maintain cleanliness to avoid contaminants. Incorrect mounting can reduce the service life of the bearing.
