The TIMKEN double-row tapered roller bearing is an assembly of two rows of tapered rollers mounted on a common cone, designed to support radial and axial loads in both directions. It is used in applications requiring high load capacity and rigidity, such as gearboxes, drive shafts and industrial equipment. MR Accesorios Industriales sells this brand and advises you on choosing the correct designation for your equipment.
The designation is interpreted in blocks. In the examples LL669810XD and LL789910XD, the prefix LL indicates the dimension series, followed by numbers that define the size. The suffix XD indicates a construction variant within the family, which corresponds to a two-row bearing with cone and cup assembled. Knowing these parts allows you to identify the exact reference you need and request a quote without errors.
In Argentine industry, TIMKEN bearings are used in speed reducers, road machinery, mining equipment, mills and conveyors. They also appear in railway applications and agricultural machinery, where combined loads and severe conditions demand a robust and durable bearing. Their double-row design allows replacing two single-row bearings in a more compact space, simplifying installation and improving the rigidity of the assembly.
To correctly select a bearing, take into account the radial and axial load capacity, the operating speed and the environmental conditions. Sealing and lubrication are critical: choose the appropriate lubricant according to temperature and contamination, and ensure precise alignment to avoid additional stresses. Installation must be carried out with appropriate tools and following the manufacturer's recommendations to guarantee the bearing's service life.
TIMKEN bearings are interchangeable with those of other leading brands, provided the main dimensions and execution type match. When looking for a replacement, verify the complete code and tolerances. At MR Accesorios Industriales we will indicate the compatible alternative. Write to us on WhatsApp with the code or model you need and we will quote it promptly.
