How to read SKF 30208 R
- 302Series
- Tapered roller bearings, 302 series. For the same bore, each series has a different outside diameter and width.
- 08Bore
- 40 mm bore: 08 × 5.
- RSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
30208 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF 30208 R bearing has a 40 mm bore, a 80 mm outside diameter and a 19.75 mm total width (40 x 80 x 19.75 mm).

The SKF R series tapered roller bearing is a component designed to support combined radial and axial loads. Its construction with tapered raceways and rollers allows linear contact that distributes the load better. It is used in applications where power must be transmitted precisely, such as gearboxes, machine tool spindles and rolling systems. At MR Accesorios Industriales we carry it as part of our SKF bearing line.
The R series designation is interpreted as follows: the base number, such as 30208, indicates the size and load capacity according to international standards. The final letter R indicates a construction variant within the tapered roller family. In the example 30208 R, the numeric code defines the main dimensions, while the R may refer to a specific cage design or a particular treatment. To choose the correct bearing, always follow the complete part number shown on the drawing or on the equipment nameplate.
These bearings are used in industries such as food processing, metallurgy, cement and mining. In Argentina they are commonly found in speed reducers, plastic industry machinery, conveying equipment and pump shafts. They are also used in the automotive sector and in agricultural machinery, where combined loads and demanding conditions require a robust and reliable bearing.
To select a tapered roller bearing, consider the radial and axial load, the rotational speed and the working environment. Installation requires careful alignment and proper axial adjustment, since these bearings are sensitive to incorrect clearance. Lubrication must be appropriate for the temperature and speed, and sealing must protect against contaminants. At MR Accesorios Industriales we can advise you with the exact part number.
Regarding equivalents, SKF R series tapered roller bearings can be interchanged with products from other brands that follow the same dimensional and load capacity standards. Always verify the complete part number and tolerances before replacing one bearing with another of a different brand. Interchangeability depends on the main dimensions and chamfer design matching.
