How to read SKF 31308/CL7C
- 313Series
- Tapered roller bearings, 313 series. For the same bore, each series has a different outside diameter and width.
- 08Bore
- 40 mm bore: 08 × 5.
- CL7CSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
31308 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF 31308/CL7C bearing has a 40 mm bore, a 90 mm outside diameter and a 25.25 mm total width (40 x 90 x 25.25 mm).

SKF tapered roller bearings are components designed to withstand combined radial and axial loads. Their tapered roller and raceway design allows linear contact that distributes loads better. They are used in applications requiring high load capacity and rigidity, such as gearboxes, wheel axles and industrial machinery. MR Accesorios Industriales sells this line as part of its SKF bearing line.
The designation of these bearings is interpreted as follows: the main number, for example 31308, indicates the size and dimensional series. The suffix CL7C specifies a design with controlled tolerances and internal clearance, optimized for applications requiring high precision and rigidity. In the examples 31308/CL7C, 31309/CL7C, 31310/CL7C, 31312/CL7C and 31313/CL7C, the base number identifies the size, while CL7C remains constant for this variant. Knowing this nomenclature lets you select the correct bearing according to the diameter and operating conditions.
These bearings are used in industries such as automotive, metallurgical, cement and mining, as well as in power transmission equipment. In Argentina, they are common in gearboxes, machine tool spindles, overhead cranes and conveyor rollers. Their ability to withstand combined loads makes them suitable for assemblies where the shaft must withstand both radial and axial forces, ensuring stable and durable operation under demanding conditions.
To select the right bearing, take into account the magnitude and direction of the loads, the rotational speed and the environmental conditions. Mounting requires precise alignment to avoid additional stresses. Lubrication must be suitable for the operating temperature and speed, and sealing must protect against contaminants. The internal clearance is already defined at the factory, so it does not need to be adjusted. Follow the manufacturer's recommendations for mounting and axial fixing.
As for equivalents, SKF tapered roller bearings can be interchanged with those from other recognized brands, provided that the main dimensions and internal clearance match. SKF tapered roller bearings have equivalents in other manufacturers' catalogs, but it is essential to verify tolerances and the exact design. Not all suffixes are interchangeable; always check the technical specifications before replacing one bearing with another of a different brand.

Frequently Asked Questions
- What are the dimensions of the SKF 31308/CL7C bearing?
- The SKF 31308/CL7C bearing has a 40 mm bore, a 90 mm outside diameter and a 25.25 mm total width (40 x 90 x 25.25 mm). These are the standardised boundary dimensions (ISO 355) of the basic designation 31308.
- What does the CL7C suffix mean on these SKF bearings?
- The CL7C suffix indicates a variant with stricter dimensional and rotational tolerances, and reduced internal clearance. This provides greater precision and rigidity, suitable for applications requiring exact clearance control and high rotational accuracy.
- How do I choose the right SKF tapered roller bearing for my equipment?
- You should consider radial and axial loads, speed, temperature and available space. The base number (e.g. 31308) defines the main dimensions. With that data and the complete code, we can advise you on selecting the right bearing.
- Are SKF tapered roller bearings interchangeable with other brands?
- They can be interchangeable with bearings from other brands that have the same dimensions and internal clearance. However, always verify tolerances and design, as small differences can affect performance. Ask us about specific equivalents.
