Decoding SKF 31313/CL7C
- 313Series
- Tapered roller bearings, 313 series. Series differ in outside diameter and width even when the bore is the same.
- 13Bore
- Bore 65 mm (13 × 5).
- CL7CSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
31313 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 31313/CL7C measures 65 mm across the bore and 140 mm across the outside diameter; its total width is 36 mm (65 x 140 x 36 mm).

SKF CL7C series tapered roller bearings are built for arrangements that see radial and axial forces at the same time. The angled rollers and raceways make line contact, which spreads the load across the assembly. Gearboxes, wheel axles and other industrial machinery rely on this type of bearing where rigidity and load capacity matter. MR Industrial Accessories supplies this SKF line to customers in the US and Latin America.
Reading the code helps you match a bearing to the shaft and housing. The base number, such as 31308, sets the size and dimensional series. The CL7C suffix stays the same across this variant and points to a design with controlled tolerances and internal clearance, intended for work that calls for precision and stiffness. Examples in the line include 31308/CL7C, 31309/CL7C, 31310/CL7C, 31312/CL7C and 31313/CL7C. Once you know how the designation is put together, you can pick the right unit from the diameter and the operating conditions.
These bearings turn up in automotive, metallurgical, cement and mining operations, and in power transmission equipment. Common mounting points include gearboxes, machine tool spindles, overhead cranes and conveyor rollers. Because they take combined loads, they suit shafts that must carry radial and axial forces together, keeping operation steady under demanding conditions.
Selection starts with the size and direction of the loads, the speed and the environment. Alignment during mounting matters, since misalignment adds stress. Choose a lubricant that matches the operating temperature and speed, and use sealing to keep contaminants out. Internal clearance is set at the factory, so no adjustment is needed on site. For mounting and axial fixing, follow the manufacturer's instructions.
Equivalents exist in other recognized brands when the main dimensions and internal clearance line up. Not every suffix crosses over, so check tolerances and the exact design before swapping one brand for another. If you send the complete code, we can review the technical details with you.

Frequently asked questions
- SKF 31313/CL7C bearing: what are its dimensions?
- SKF 31313/CL7C measures 65 mm across the bore and 140 mm across the outside diameter; its total width is 36 mm (65 x 140 x 36 mm). Those are the boundary dimensions standardized in ISO 355 for basic designation 31313.
- What does the CL7C suffix mean on these SKF bearings?
- CL7C marks a variant with tighter dimensional and rotational tolerances and reduced internal clearance. That combination gives more precision and rigidity where exact clearance control and rotational accuracy are needed.
- How do I choose the right SKF tapered roller bearing for my equipment?
- Look at radial and axial loads, speed, temperature and the space available. The base number, for example 31308, defines the main dimensions. With those details and the complete code, we can help you select the right bearing.
- Are SKF tapered roller bearings interchangeable with other brands?
- They can be interchanged with bearings from other brands that share the same dimensions and internal clearance. Always verify tolerances and design, since small differences can affect performance. Ask us about specific equivalents.
