How to read SKF 6307 M/C3
- 63Series
- Deep groove ball bearings, 63 series. For the same bore, each series has a different outside diameter and width.
- 07Bore
- 35 mm bore: 07 × 5.
- M/C3Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
6307 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF 6307 M/C3 bearing has a 35 mm bore, a 80 mm outside diameter and a 21 mm width (35 x 80 x 21 mm).

The SKF deep groove ball bearing is a thin-section component with high radial load capacity, designed to withstand combined loads in applications where axial space is limited. Its single row of balls and machined brass cage construction provides smooth operation and long service life. It is ideal for electric motors, pumps, fans and gearboxes operating at moderate and high speeds.
The designation of these bearings is read from left to right: the first two digits indicate the dimension series, in this case the 60 series of thin section. The next two digits correspond to the bore diameter code; for example, in 6014 the suffix 14 indicates a bore diameter of 70 mm. The suffixes M/C3 and M/C4 indicate a machined brass cage and a radial internal clearance greater than normal, suitable for applications with interference fits or elevated temperatures.
These bearings are used in a wide variety of industrial equipment in Argentina: low and medium power electric motors, centrifugal pumps, industrial fans, screw compressors, machine tools and speed reducers. Their ability to withstand moderate radial and axial loads makes them versatile for belt or gear drives, where precise and low-maintenance support is required.
To select the appropriate bearing, consider the radial and axial load, rotation speed and environmental conditions. C3 or C4 internal clearance is recommended when the shaft fit is an interference fit or when the operating temperature exceeds 100 °C. Mounting must be done with suitable tools, avoiding direct blows on the balls. Lubrication can be with grease or oil, and it is essential to maintain alignment between shaft and housing to avoid additional loads.
Regarding equivalences, SKF deep groove ball bearings can be interchanged with products from other brands that follow the same ISO designation, such as FAG, NSK or NTN, as long as tolerances and internal clearance are respected. It is important to verify the cage suffix and clearance, since not all brands offer the same options. For replacements, always compare the main dimensions and operating conditions.

Frequently Asked Questions
- What are the dimensions of the SKF 6307 M/C3 bearing?
- The SKF 6307 M/C3 bearing has a 35 mm bore, a 80 mm outside diameter and a 21 mm width (35 x 80 x 21 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6307.
- What does the suffix M/C3 mean in an SKF bearing?
- The M indicates a machined brass cage, which better withstands vibrations and high temperatures. C3 indicates a radial internal clearance greater than normal, recommended for interference fits or thermal differences between shaft and housing.
- How do I choose between a bearing with C3 clearance and one with C4 clearance?
- C4 clearance is even greater than C3 and is used in applications with higher temperatures or tighter fits. If you do not have extreme conditions, C3 is usually sufficient. Consult us with your equipment data.
- Can I replace an SKF bearing with another brand?
- Yes, as long as the ISO designation matches in dimensions and clearance. Brands such as FAG, NSK or NTN offer equivalents. Verify the cage type and internal clearance to ensure interchangeability.
