TIMKEN double row tapered roller bearings are units that combine two rows of tapered rollers in a single assembly, allowing them 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 mining equipment. MR Accesorios Industriales sells this line with technical support so you can choose the correct designation.
The designation of these TIMKEN bearings is structured with the letter K, a series number and the suffix R. For example, K107577R, K107578R, K107581R and K107582R belong to one series, while K109151R, K109152R, K114294R and K114295R correspond to another series. The letter K indicates the double row assembly type, the number identifies the size and the final letters indicate design or sealing variants. To correctly interpret each code, it is essential to consult the complete designation.
These bearings are used in industries such as mining, cement, steel and heavy industry in general. In Argentina, they are commonly found in speed reducers, mills, conveyor belts and earthmoving equipment. Their ability to support combined loads and their rigidity make them suitable for shafts where precision and durability are required. MR Accesorios Industriales has extensive experience in supplying bearings for these applications.
To select the correct bearing, consider the radial and axial load, the rotation speed and the environmental conditions. Different series may differ in their internal construction and sealing type. It is important to verify the internal clearance and the lubrication method. During mounting, ensure precise alignment and proper fit to avoid premature failures. If you need assistance, our technical team can help you.
Regarding interchangeability, TIMKEN bearings can be interchanged with those of other recognized brands, but always verifying dimensions and load capacities. It is not enough for the code to be similar; the complete designation and tolerances must be compared. To find the compatible alternative, contact us with the original code and we will indicate the option that best suits your equipment.
