How to read SKF 6209/C3S1
- 62Series
- Deep groove ball bearings, 62 series. For the same bore, each series has a different outside diameter and width.
- 09Bore
- 45 mm bore: 09 × 5.
- C3S1Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
6209 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF deep groove ball bearings are essential components for supporting radial and axial loads in industrial machinery. Their design with a single row of balls and deep raceways allows high speeds and smooth operation. At MR Accesorios Industriales we carry this line with different internal clearance and heat treatment specifications to adapt to various applications.
The designation of these bearings follows the SKF system: the basic number indicates the type and the dimension series. For example, 6207 corresponds to a deep groove ball bearing of the 62 series, with a bore diameter of 35 mm. The suffixes provide key information: C3 indicates a radial internal clearance greater than normal, suitable for applications with tight fits or thermal differences; S1 indicates a special heat treatment for high operating temperatures. Meanwhile, C4 denotes an even greater clearance, and S0 a standard heat treatment. Thus, 6207/C3S1 combines C3 clearance and S1 treatment, while 6314/C4S0 has C4 clearance and standard treatment.
These bearings are used in a wide variety of industrial equipment in Argentina: electric motors, centrifugal pumps, fans, conveyor belts, gearboxes and machine tools, among others. Their ability to support moderate radial and axial loads makes them versatile. In the food, chemical and petrochemical sectors, where temperature and speed conditions are demanding, the variants with C3 or C4 clearance and specific heat treatments offer reliable performance.
To select correctly, consider the load, the speed, the operating temperature and the type of fit. A greater internal clearance (C3, C4) compensates for the reduction of clearance due to interference during mounting or thermal expansion. The S1 or S0 treatment influences dimensional stability at high temperatures. During mounting, ensure precise alignment and adequate lubrication; sealing will depend on the environment. Follow the manufacturer's recommendations to avoid premature failures.
As for equivalents, SKF deep groove ball bearings can be interchanged with those of other brands that follow the same dimensional designation and clearance and treatment specifications. However, always verify the tolerances and load capacities, since they can vary between manufacturers. For replacements, it is essential to compare not only the basic number but also the suffixes, which define critical operating characteristics.

Frequently Asked Questions
- What are the dimensions of the SKF 6209/C3S1 bearing?
- The SKF 6209/C3S1 bearing has a 45 mm bore, a 85 mm outside diameter and a 19 mm width (45 x 85 x 19 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6209.
- What does the C3 suffix mean on an SKF bearing?
- The C3 suffix indicates a radial internal clearance greater than normal. It is used when the mounting fit is tight or when there are thermal differences between the inner and outer rings, to prevent the bearing from being left without clearance and failing prematurely.
- What is the difference between S0 and S1 treatments?
- S0 is the standard heat treatment for normal operating temperatures. S1 is a special treatment that provides greater dimensional stability at high temperatures, allowing the bearing to maintain its properties in more demanding applications.
- Can I replace an SKF bearing with another brand?
- Yes, as long as the dimensional designation and the suffixes match. It is important to verify that the tolerances and load capacities are equivalent. To be sure, consult our specialists by sending the part number by WhatsApp.
