Decoding SKF 30208 R
- 302Series
- Tapered roller bearings, 302 series. Series differ in outside diameter and width even when the bore is the same.
- 08Bore
- Bore 40 mm (08 × 5).
- RSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
30208 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 30208 R measures 40 mm across the bore and 80 mm across the outside diameter; its total width is 19.75 mm (40 x 80 x 19.75 mm).

For machinery that must handle both radial and axial forces at once, the SKF R series tapered roller bearing is a common choice. Its tapered raceways and rollers create linear contact that spreads the load across the bearing. You will find these bearings in gearboxes, machine tool spindles and rolling systems where power transmission needs to be precise. MR Industrial Accessories supplies this SKF bearing line to customers across the United States and Latin America.
Reading the part number helps you order the right bearing. Take 30208 R: the base number 30208 sets the size and load capacity according to international standards, while the trailing R denotes a construction variant inside the tapered roller family. That letter can point to a specific cage design or a particular treatment. Always rely on the full part number from your drawing or equipment nameplate when selecting a replacement.
These bearings appear in food processing, metallurgy, cement and mining operations. In speed reducers, plastic industry machinery, conveying equipment and pump shafts, they handle the combined loads that come with demanding conditions. Automotive and agricultural machinery also use them where robustness and reliability matter.
Selection depends on the radial and axial load, the rotational speed and the working environment. During installation, pay attention to alignment and axial adjustment because these bearings are sensitive to incorrect clearance. Use lubrication suited to the temperature and speed, and make sure sealing keeps contaminants out. Our team can help you match the exact part number to your application.
SKF R series tapered roller bearings can be interchanged with other brands that follow the same dimensional and load capacity standards. Before swapping brands, verify the complete part number and tolerances. Interchangeability hinges on the main dimensions and chamfer design lining up.

Frequently asked questions
- SKF 30208 R bearing: what are its dimensions?
- SKF 30208 R measures 40 mm across the bore and 80 mm across the outside diameter; its total width is 19.75 mm (40 x 80 x 19.75 mm). Those are the boundary dimensions standardized in ISO 355 for basic designation 30208.
- What does the R indicate in part number 30208 R?
- The final R shows a construction variant within the SKF tapered roller bearing series. It may refer to a specific cage design or a particular treatment. Always check the drawing or equipment documentation to interpret the part number correctly.
- How can I tell if an SKF R series tapered roller bearing fits my machine?
- Look at the main dimensions, load capacity and mounting type. The complete part number, such as 30208 R, provides that information. If you are unsure, send us the part number by WhatsApp and we will advise you with no obligation.
- What lubrication should I use for these bearings?
- It depends on speed, temperature and environment. For general industrial use, high-quality grease is common, but high-speed cases may require oil. Contact us with your equipment data and we will guide you.
