How to read SKF 6311/VA201
- 63Series
- Deep groove ball bearings, 63 series. For the same bore, each series has a different outside diameter and width.
- 11Bore
- 55 mm bore: 11 × 5.
- VA201Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
6311 is the standard (ISO) basic designation: it defines the type, the series and the bore.

SKF VA201 series deep groove ball bearings are components designed to withstand elevated temperatures, with a metal cage and special lubricant that resists heat. They are used in applications where conventional bearings degrade due to thermal effects, such as furnaces, extraction fans or conveyors in foundries. MR Accesorios Industriales supplies this line, with technical advice to choose the right size for your equipment.
The designation of these bearings combines the size code (for example, 6202, 6203, 6204, 6206, 6208, 6209, 6210, 6305) with the suffix /VA201. The base number indicates the series and size: the 62 series is medium section, the 63 series is wider and has higher capacity. The VA201 suffix identifies a special execution with a steel sheet cage and high-temperature lubricant, suitable for demanding thermal conditions. Knowing this nomenclature allows you to quickly interpret the bearing's characteristics.
These bearings are used in industries where heat is a critical factor: foundry plants, industrial furnaces, heat treatment lines, induced draft fans, clinker conveyors and drying equipment. In Argentina, they are common in the metallurgical, cement, ceramic and food sectors. Their ability to withstand elevated temperatures without losing lubrication makes them ideal for rotation points exposed to radiant or convective heat sources.
To select the right bearing, take into account the working temperature, load and speed. The VA201 suffix is intended for a specific thermal range; verify that it is compatible with your application. During mounting, ensure correct alignment and avoid impacts that could damage the raceways. The factory lubrication is part of the execution; do not replace it with a conventional grease. If the environment has dust or moisture, consider additional protections.
Regarding equivalences, other manufacturers offer bearings with special heat treatments and high-temperature lubricants, but designations may vary. There is no automatic universal interchangeability: always confirm dimensions, internal clearance and maximum permissible temperature. At MR Accesorios Industriales we can guide you on alternatives available on the market, respecting your equipment's specifications and without compromising performance.

Frequently Asked Questions
- What are the dimensions of the SKF 6311/VA201 bearing?
- The SKF 6311/VA201 bearing has a 55 mm bore, a 120 mm outside diameter and a 29 mm width (55 x 120 x 29 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6311.
- What does the VA201 suffix mean on an SKF bearing?
- The VA201 suffix identifies a special execution with a steel cage and high-temperature lubricant. It is designed for applications where the bearing must withstand heat without losing its properties. It is not a size code, but a code for thermal and lubrication characteristics.
- Can I use a VA201 bearing at room temperature?
- Yes, but it is not the most efficient option. The VA201 is optimized for high temperature; at room temperature you can use a standard bearing. If your equipment works across a wide range, contact us and we will evaluate the best option for your case.
- How do I request a quote for an SKF VA201 bearing?
- Send the complete code on WhatsApp, for example 6204/VA201, along with the quantity. At MR Accesorios Industriales we will reply with the quote and alternatives. We can also advise you if you need help identifying the correct code.
