TIMKEN 3200-3300 series angular contact ball bearings are components designed to support combined radial and axial loads in a single direction. Their contact angle design enables applications requiring high precision and rigidity, such as machine tool spindles, pumps and gearboxes. MR Accesorios Industriales supplies this line backed by more than 80 years in the Argentine industrial market.

The designation of this series is read with the four-digit basic number that identifies the size and the suffix A that indicates a construction variant within the family. For example, 3201 A, 3202 A and 3203 A correspond to the smallest sizes, while 3207 A and 3208 A are the largest in the series. The suffix A usually indicates a modification in the contact angle or in the cage, according to the manufacturer's standard. To choose the correct part number, take into account the housing dimensions and the load direction.

These bearings are used in industries such as metalworking, food and petrochemical, in equipment such as centrifugal pumps, compressors, high-speed fans and milling machine spindles. In Argentina, they are common in machine tool maintenance and in production lines requiring precision. Their ability to support axial loads in one direction makes them ideal for applications with constant thrust, such as helical gears or worm screws.

To select the right bearing, consider the magnitude and direction of the loads, the rotation speed and the environmental conditions. Mounting must ensure precise alignment between shaft and housing, since these bearings are sensitive to misalignment. Lubrication can be grease or oil, depending on the speed and working temperature. Sealing will depend on external contamination: in dirty environments, additional protection is recommended. Internal clearance is adjusted by preload or axial clearance, depending on the equipment design.

Regarding equivalences, TIMKEN 3200-3300 series angular contact bearings can be interchanged with products from other brands that follow the same dimensional and angle nomenclature. It is essential to verify tolerances and contact angle, since small differences can affect performance. For safe interchangeability, always compare technical specifications and consult with our technical team. Not all brands maintain exactly the same load capacities.
