This SKF deep groove ball bearing carries radial and axial loads in rotating equipment. Its single-row ball design supports high speeds with low maintenance. MR Industrial Accessories LLC supplies it to customers across the United States and Latin America, and the team can help you confirm the right configuration for your application.
The part number tells you what you are getting. In 6203-2RS2/C4S1VT127, the 62 prefix identifies the medium section series and 03 sets the bore size. The 2RS2 suffix means rubber seals on both sides, C4 indicates radial clearance above standard, S1 refers to heat treatment for high temperatures, and VT127 specifies a particular grease. Reading these codes correctly is the first step in choosing a bearing that fits the operating conditions.
Typical uses include electric motors, centrifugal pumps, fans, conveyors and machine tools. The bearing handles combined loads and runs at high speeds, which makes it suitable for food, chemical, petrochemical and general manufacturing environments. When you are unsure which suffix combination your equipment needs, the MR team can review the application with you.
Selection depends on load, speed and the surrounding environment. The 2RS2 seal keeps out dust and moisture in contaminated areas. C4 clearance is the choice when temperature differences between the inner and outer rings are expected. VT127 lubrication is intended for elevated temperatures. During mounting, align the bearing precisely and avoid impacts that could damage the raceways; correct lubrication supports service life.
Bearings from other manufacturers that match the same dimensions and tolerances can serve as replacements. Before substituting, check the full code and the seal, clearance and lubricant specifications, because suffixes are not always equivalent between brands. MR Industrial Accessories LLC can advise on compatibility and alternatives.

Frequently asked questions
- SKF 6203-2RS2/C4S1VT127 bearing: what are its dimensions?
- SKF 6203-2RS2/C4S1VT127 measures 17 mm across the bore and 40 mm across the outside diameter; its width is 12 mm (17 x 40 x 12 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6203.
- What does the 2RS2 suffix indicate on an SKF bearing?
- It means the bearing has rubber seals on both sides, which protect against dust, water and other contaminants. This configuration suits dirty or humid operating conditions.
- When should I use a C4 radial clearance?
- C4 is an above-standard clearance. It is recommended when the inner and outer rings operate at different temperatures or when high speeds generate thermal expansion, helping to avoid excessive preload.
- How do I request a quote for this bearing?
- Send the complete bearing code by WhatsApp or email. MR Industrial Accessories LLC will respond promptly with a quote and can also discuss other configurations or equivalent options.
