SKF 33 series deep groove ball bearings are double row angular contact bearings designed to support radial and axial loads in both directions. Their compact and robust construction makes them ideal for applications requiring high rigidity and precision. At MR Accesorios Industriales we carry this series with rubber seals and C3 internal clearance, ready for demanding environments.

The designation of these bearings is read as follows: the base number, for example 3309, 3310 or 3311, indicates the size and series. The A suffix indicates an optimized internal design. 2RS1 means double rubber seal on both sides, which retains lubricant and blocks contaminants. C3 indicates a radial internal clearance greater than standard, and MT33 identifies the type of high-quality grease with which they are lubricated from the factory. Thus, a code such as 3310 A-2RS1/C3MT33 summarizes all these characteristics.

These bearings are used in equipment where combined loads and moderate speeds are common. In Argentine industry you will find them in centrifugal pumps, compressors, industrial fans, machine tools and transmission equipment. They also appear in agricultural applications and in conveyors. Their double row and angular contact make them suitable for supporting axial forces in both directions, something a single row deep groove ball bearing cannot achieve with the same efficiency.

To select the correct bearing, take into account the radial and axial load it must support, the rotation speed and the environmental conditions. C3 clearance is recommended when there are thermal differences between the shaft and the housing, or when greater tolerance is required during mounting. 2RS1 seals protect against dust and moisture, but if the environment is very dirty or there is water spray, consider additional protections. Factory lubrication with MT33 grease covers a wide temperature range, although in severe applications periodic relubrication may be necessary.

When replacing a bearing, verify that the dimensions and clearance match the original. Equivalences between brands exist, but they are not always direct: the same code may vary in suffixes and performance. It is always advisable to consult a specialist before substituting one brand for another. At MR Accesorios Industriales we can advise you to find the right option for your application.
