SKF M/C3VQ series deep groove ball bearings handle radial and axial loads in both directions. They combine a machined brass cage with C3 internal clearance, making them a fit for higher speeds and elevated temperatures. MR Industrial Accessories supplies this line to customers across the United States and in several Latin American countries, with help selecting the right variant.
Reading the designation tells you what you are ordering. Take 6313 M/C3VQ335: the numeric prefix gives the size and dimensional series. The M stands for a machined brass cage, chosen for high speeds and elevated temperatures. C3 means radial internal clearance above standard, which matters when interference fits or thermal gradients are present. The VQ letters and the trailing numbers, as in 6330 M/C3VQ658, point to particular quality specifications and execution variants, which may include special tolerances or treatments. Check the full designation before assuming interchangeability.
These bearings appear in electric motors, centrifugal pumps, fans, compressors, conveyor belts, and equipment in the food, cement and steel industries. Machine tool spindles and speed reducers are common locations. The M/C3VQ combination is often chosen where lubrication or temperature conditions are demanding.
Selection comes down to load type, rotational speed and the operating environment. Sealing is a key decision: these bearings can be mounted with seals or shields depending on how contaminated the surroundings are. Choose C3 clearance when the shaft or housing fit reduces internal clearance, or when operating temperature runs high. Grease or oil lubrication, applied correctly, extends service life. During mounting, keep alignment precise and avoid impacts that could damage the raceways. Follow the manufacturer's recommendations for fit and cleanliness.
Deep groove ball bearings from different manufacturers can be interchanged when the main dimensions, internal clearance and cage type match. Designations with specific suffixes such as M/C3VQ may carry particularities that are not always equivalent between brands, so verify the technical specifications before replacing one bearing with another. MR Industrial Accessories can advise on the best option for your application.

Frequently asked questions
- SKF 6313 M/C3VQ335 bearing: what are its dimensions?
- SKF 6313 M/C3VQ335 measures 65 mm across the bore and 140 mm across the outside diameter; its width is 33 mm (65 x 140 x 33 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6313.
- What does the C3 suffix mean on these bearings?
- C3 indicates radial internal clearance greater than standard. It is used when the interference fit on the shaft or housing reduces clearance, or when high operating temperatures could cause expansion that affects operation.
- What is the difference between the M cage and other cage types?
- The M cage is machined brass, which gives it greater strength and capacity for high speeds and temperatures. Other cages, such as stamped steel or polyamide, suit less demanding conditions. The choice depends on the application.
- How can I request a quote for these bearings?
- Send the full bearing part number by WhatsApp or email. MR Industrial Accessories quotes it and provides alternatives for your requirement, and can help identify the right part if needed.
