FAG K-A series tapered roller bearings are components designed to support combined radial and axial loads. Their construction with tapered races and rollers allows linear contact that distributes the load better. They are used in applications requiring high load capacity and rigidity, such as gearboxes, wheel axles and industrial machinery. MR Accesorios Industriales sells this line backed by more than 80 years in the Argentine market.
The K-A series designation is interpreted from the cone and cup codes that make it up. For example, in K336-332-A, the letter K indicates that it is a tapered roller assembly, while the numbers identify the dimensions and race design. The suffix A may indicate a variant in contact angle or precision. Each cone and cup combination defines a specific bearing, so it is essential to verify the complete code when inquiring.
These bearings are used in a wide variety of industries in Argentina. They are found in vehicle transmissions, road machinery, mining equipment, flour mills and conveyor systems. They are also present in speed reducers, machine tool spindles and rolling mill rolls. Their ability to support combined loads makes them suitable for shafts that must withstand both radial and axial forces, especially in applications with continuous rotary motion.
To correctly select a tapered roller bearing, consider radial and axial load, rotation speed and environmental conditions. Mounting requires precise alignment and proper adjustment of internal clearance, which is usually regulated by lock nuts or shims. Lubrication can be with grease or oil, depending on speed and working temperature. It is important to verify sealing to prevent contamination by dust or particles, which extends bearing service life.
Regarding equivalences and interchangeability, tapered roller bearings are manufactured under international standards that allow replacing one brand with another if dimensions and cone and cup code match. However, there may be differences in tolerances, angles or surface treatments that affect performance. Therefore, it is always advisable to consult a specialist before replacing one bearing with another of a different brand. MR Accesorios Industriales can advise you with the exact code you need.
