The deep groove ball bearing is the most common type of bearing. It supports moderate radial and axial loads in both directions, and is suitable for high speeds. SKF deep groove ball bearing series are characterized by their thin section and their ability to work in tight spaces. They are used in electric motors, pumps, fans and light transmissions. MR Accesorios Industriales sells this line with technical advice so you can choose the right internal clearance.

The designation of these bearings follows a clear scheme. The basic number indicates the size and series. Each series has a characteristic section compared to other series. Suffixes provide additional information: /C2 indicates an internal clearance smaller than normal, while /C3 indicates an internal clearance larger than normal. For example, 6005/C2 and 6005/C3 share the same size but have different clearance. Knowing these suffixes is key to selecting the right bearing for the application.

These bearings are used in a wide variety of industrial equipment in Argentina. They are common in low- and medium-power electric motors, centrifugal pumps, fans, small compressors, machine tools and transmission equipment. They are also found in automotive applications, such as alternators and tensioners. Their versatile design makes them suitable for the food, textile, chemical and general manufacturing industries. Deep groove ball bearing series are common in equipment where radial space is limited and smooth, quiet operation is required.

To select the right bearing, take into account the load, speed and environmental conditions. C2 internal clearance is used when a more precise fit and low operating temperatures are needed, while C3 is for applications with high temperatures or interference fits, where clearance is reduced during operation. Sealing can be open, with shields or with seals, depending on contamination. Lubrication can be grease or oil. During installation, ensure correct alignment and avoid impacts that damage the raceways. Always consult the manufacturer's recommendations.

On the market there are equivalent bearings from other brands that follow similar designations. Deep groove ball bearings with C2 or C3 suffixes are an international standard, so you will find interchangeability between different manufacturers. However, not all products have the same quality or tolerances. It is important to verify that the bearing complies with the applicable standards. MR Accesorios Industriales sells SKF, which guarantees backing and reliability. If you need to replace a bearing, you can compare the dimensions and the internal clearance.

If you already have the code of your bearing, send it via WhatsApp to MR Accesorios Industriales and we will quote you. We can also advise you if you are unsure between a C2 or C3 clearance, or if you need a variant with special sealing. At MR we have the experience to help you choose the right SKF bearing for your equipment. Write to us and we will reply shortly.

Frequently Asked Questions

What are the dimensions of the SKF 6011/C3 bearing?
The SKF 6011/C3 bearing has a 55 mm bore, a 90 mm outside diameter and a 18 mm width (55 x 90 x 18 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6011.
What does the C3 suffix mean on an SKF bearing?
The C3 suffix indicates a radial internal clearance larger than normal. It is used in applications where operating temperatures are high or where an interference fit reduces clearance during mounting. This prevents the bearing from running preloaded.
What is the difference between a 6005/C2 bearing and a 6005/C3?
Both share the same size, but the 6005/C2 has an internal clearance smaller than normal, while the 6005/C3 has a larger clearance. The choice depends on the operating conditions: C2 for precise fits and low temperatures, C3 for high temperatures or interference fits.
How do I know if I can replace a bearing from another brand with an SKF one?
If the bearing from another brand has the same basic designation and suffixes, such as 6000/C3, it is interchangeable. Still, verify the dimensions and tolerances. At MR Accesorios Industriales we advise you so that the replacement is safe and reliable.
