The SKF deep groove ball bearing is an essential component for supporting radial and axial loads in industrial machinery. Its single-row ball design allows high speeds and low maintenance. At MR Accesorios Industriales we supply this brand. Ideal for electric motors, pumps and transmissions.
The designation of these bearings is interpreted by their suffixes. For example, in 6203-2RS2/C4S1VT127, the prefix 62 indicates the medium section series, 03 the bore size. The suffix 2RS2 indicates double rubber seal, C4 a radial clearance greater than standard, S1 heat treatment for high temperatures and VT127 a specific grease. Knowing these codes allows you to select the right bearing for each application.
In Argentine industry, SKF deep groove ball bearings are used in electric motors, centrifugal pumps, fans, conveyors and machine tools. Their ability to support combined loads and operate at high speeds makes them versatile. MR Accesorios Industriales supplies them for sectors such as food, chemical, petrochemical and general manufacturing, with technical advice to choose the correct configuration.
To select the bearing, consider load, speed and environmental conditions. The 2RS2 seal protects against dust and moisture, ideal for contaminated environments. The C4 clearance is recommended when there are thermal gradients between inner and outer rings. The VT127 lubrication is for elevated temperatures. During mounting, ensure precise alignment and avoid impacts that damage the raceways. Proper lubrication extends service life.
SKF bearings are interchangeable with those of other brands that meet the same dimensions and tolerances. When looking for a replacement, verify the complete code and the specifications for seal, clearance and lubricant. Not all suffixes are equivalent between manufacturers. At MR Accesorios Industriales we can guide you on compatibility and alternatives.

Frequently Asked Questions
- What are the dimensions of the SKF 6203-2RS2/C4S1VT127 bearing?
- The SKF 6203-2RS2/C4S1VT127 bearing has a 17 mm bore, a 40 mm outside diameter and a 12 mm width (17 x 40 x 12 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6203.
- What does the suffix 2RS2 mean on an SKF bearing?
- The suffix 2RS2 indicates that the bearing has rubber seals on both sides, providing effective protection against the entry of dust, water and contaminants. It is ideal for applications in dirty or humid environments.
- When is a C4 radial clearance recommended?
- The C4 radial clearance is greater than standard and is recommended when the bearing operates with temperature differences between the inner and outer rings, or when high speeds are required that generate thermal expansion. It helps prevent excessive preload.
- How can I request a quote for this bearing?
- You can send us the complete bearing code via WhatsApp. At MR Accesorios Industriales we will respond with the quote and alternatives. You can also ask us about other brands or configurations.
