Double row angular contact ball bearings

The double row angular contact ball bearing is a component with two rows of balls arranged in parallel and inclined raceways, designed to support radial and axial loads in both directions within a single housing. It is chosen by the shaft and housing diameter, the predominant load type, the rotational speed, and the required internal clearance; when the application requires high rigidity and precision, this construction replaces two single-row bearings and simplifies assembly. At MR Accesorios Industriales we sell 320 SKF references in this line.

The designations you will find combine the design and sealing type. In 3305 A-2RS1TN9/C3B426 and PER.5205-2RSW, the prefix or base number identifies the series and the suffix 2RS indicates double contact seals; the designation C3 corresponds to a larger-than-standard internal clearance. In MRC.5205CFF and AGHB2047-S50 there are manufacturing and sealing variants specific to each series. The codes BEAS 020052 C-2RSH and BEAM 020068 C-2RSH correspond to double row versions with 2RSH sealing, and the acronym BEAS/BEAM distinguishes the type of construction and the arrangement of the rows.

These bearings are used in equipment where the shaft must remain rigid and centered: gear reducers and gearboxes, pumps, compressors, spindles, machine tools, process fans, and industrial transmissions. They also appear in applications where the axial load changes direction during the work cycle, because the double row absorbs thrust in both directions without the need to mount two opposed bearings.

To request a quote we need the complete part number that appears on the bearing or in the equipment drawing. If you do not have it at hand, send us the shaft diameter, outer diameter, width, sealing type and, if possible, a photo of the part or of the side inscription. With that data we verify the equivalence within the SKF line and confirm the corresponding reference.

If the application has axial load in one direction only or requires greater radial capacity, it is advisable to evaluate other families: single-row angular contact, deep groove ball bearings, or tapered roller bearings. Our technical team in Buenos Aires, Argentina, helps you define the correct option according to the equipment and type of load.
