TIMKEN double row tapered roller bearings are components designed to support radial and axial loads in both directions. They are used in applications requiring high load capacity and rigidity, such as gearboxes, transmission shafts and industrial equipment. MR Accesorios Industriales supplies this line with technical advice to select the right configuration according to the assembly and operating conditions.
The designation of these bearings combines letters and numbers that indicate constructional features. In the Y#M series, the letter Y identifies a double row configuration, while the following digits indicate dimensions and internal design. For example, Y30216M and Y30220M share the prefix 302, which provides guidance on the type of assembly. Suffixes such as M indicate modifications in cages or tolerances. The 2TS-IM and 2TS-DM series group variants with different arrangements of cones and cups. To correctly interpret each part number, it is essential to consult the complete designation.
These bearings are used in industries such as metallurgy, cement, mining and material handling. In Argentina, they are commonly found in gear reducers, mills, conveyor belts and agricultural machinery. Their ability to support combined loads and moments makes them suitable for highly demanding shafts. They are also used in lifting equipment and presses. The robustness of the double row design allows aligning and stiffening the assembly, reducing deformations and extending the service life of the system.
To select the right bearing, consider the magnitude and direction of the loads, the rotation speed and the environmental conditions. Assembly requires precise alignment and correct adjustment of the internal clearance, which can be fixed by means of nuts or shims. Lubrication must be chosen according to temperature and speed: grease for slow applications or oil for high revolutions. Sealing is key to retain lubricant and exclude contaminants; in dirty environments additional seals are recommended. Careful installation prevents premature failures.
There are equivalent bearings from other brands on the market, but interchangeability depends on dimensions and tolerances. It is not enough for the main dimensions to match; the contact angle, load capacity and cage type must be verified. Part numbers from other companies may not be directly replaceable. Therefore, when looking for a replacement, it is essential to compare the technical specifications. MR Accesorios Industriales can advise you to find the alternative compatible with your application, maintaining equipment performance.
