SKF DNRCBM series deep groove ball bearings are double row angular contact bearings designed to support combined radial and axial loads in both directions. Their design with two rows of balls and inclined raceways gives them a higher axial load capacity than a single row deep groove ball bearing, while maintaining a compact size. They are a common choice in applications requiring rigidity and precision, such as gearboxes, pumps and transmission equipment. MR Accesorios Industriales supplies this SKF line with technical advice to select the correct part number.

The designation of these bearings combines several suffixes that indicate design features. In the examples 3308 DNRCBM, 3310 DNRCBM, 3311 DNRCBM and 3313 DNRCBM, the first two digits (33) identify the double row angular contact series. The next two digits indicate the bore size: for the 3308, the bore is 40 mm; for the 3310, 50 mm; for the 3311, 55 mm; and for the 3313, 65 mm. The suffixes DNRCBM provide information on the internal design, sealing and cage, which should be verified in each case according to the application.

These bearings are used in equipment where axial loads in both directions are significant and space is limited. In Argentine industry they appear in gearboxes, centrifugal pumps, compressors, machine tools and power transmission systems. They are also found in mining equipment, cement plants and food plants, where robustness and load capacity are critical. Their double row design allows replacing more complex arrangements of two single row bearings, simplifying the housing design.

To select the right bearing, take into account the magnitude and direction of the loads, the rotational speed and the environmental conditions. The sealing — indicated by the suffixes — defines the protection against dust and moisture; in dirty or humid environments, choose versions with seals or shields. Lubrication must be suitable for the temperature and speed; in many cases they come factory lubricated, but verify compatibility with the use. Mounting requires careful alignment and, in general, an internal clearance fit that can be affected by housing and shaft interference.

When looking for a replacement, it is common to find cross-brand equivalences: a double row angular contact bearing from another manufacturer may have a different designation but equivalent standardized dimensions. Do not rely only on the part number; compare the main dimensions (bore, outer diameter and width) and the load conditions. At MR Accesorios Industriales we can help you identify interchangeability, but it is always advisable to verify the original equipment specifications. If you have doubts, consult us with the old bearing data or the housing measurements.
