Decoding SKF 6304/VA201
- 63Series
- Deep groove ball bearings, 63 series. Series differ in outside diameter and width even when the bore is the same.
- 04Bore
- Bore 20 mm (04 × 5).
- VA201Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6304 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 6304/VA201 measures 20 mm across the bore and 52 mm across the outside diameter; its width is 15 mm (20 x 52 x 15 mm).

SKF VA201 series deep groove ball bearings are built for heat-exposed rotation points. Each bearing uses a steel sheet cage and a lubricant formulated for high temperatures, so it keeps working where standard bearings would break down. Typical settings include furnaces, induced draft fans and foundry conveyors. MR Industrial Accessories supplies this line and helps you match the right size to your equipment.
Reading the code is straightforward. The base number gives series and size: 62 is the medium section, while 63 is wider and carries more capacity. Common base numbers in this range are 6202, 6203, 6204, 6206, 6208, 6209, 6210 and 6305. The /VA201 suffix then marks the special execution: steel sheet cage plus high-temperature grease. Once you know that pattern, you can tell at a glance what a bearing is meant for.
These bearings suit plants where heat drives bearing failure: foundries, industrial furnaces, heat treatment lines, induced draft fans, clinker conveyors and drying equipment. They are also used in the metallurgical, cement, ceramic and food sectors. Because the lubricant holds up under thermal load, the bearing keeps rotating at points exposed to radiant or convective heat.
When selecting, check operating temperature, load and speed. The VA201 execution covers a defined thermal range, so confirm it fits your case. During mounting, keep alignment correct and avoid impacts that could mark the raceways. The factory fill is part of the execution and should not be swapped for standard grease. In dusty or damp areas, add suitable protection.
Other makers offer heat-treated bearings with high-temperature lubricants, but the designations differ. There is no automatic universal interchange, so always verify dimensions, internal clearance and maximum permissible temperature. MR Industrial Accessories can point you to market alternatives that respect your equipment's specifications.

Frequently asked questions
- SKF 6304/VA201 bearing: what are its dimensions?
- SKF 6304/VA201 measures 20 mm across the bore and 52 mm across the outside diameter; its width is 15 mm (20 x 52 x 15 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6304.
- What does the VA201 suffix mean on an SKF bearing?
- VA201 is not a size code. It identifies a special execution with a steel sheet cage and a high-temperature lubricant, intended for bearings that must withstand heat without losing their properties.
- Can I use a VA201 bearing at room temperature?
- It will work, but it is not the most efficient choice. VA201 is optimized for high temperature; at room temperature a standard bearing is usually better. If your equipment runs across a wide range, contact us and we will review the best option.
- How do I request a quote for an SKF VA201 bearing?
- Send the full code on WhatsApp, for example 6204/VA201, with the quantity. MR Industrial Accessories will reply with the quote and alternatives, and can help you identify the correct code if needed.
