How to read SKF 22207 EK/C3
- 222Series
- Spherical roller bearings, 222 series. For the same bore, each series has a different outside diameter and width.
- 07Bore
- 35 mm bore: 07 × 5.
- EK/C3Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
22207 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF 22207 EK/C3 bearing has a 35 mm bore, a 72 mm outside diameter and a 23 mm width (35 x 72 x 23 mm).

SKF spherical roller bearings are self-aligning components with two rows of rollers, designed to withstand high radial loads and axial loads in both directions. Their spherical outer raceway allows the shaft to misalign without increasing internal stresses, making them ideal for equipment with shaft deflection or assemblies where perfect alignment is not possible. At MR Accesorios Industriales we carry the SKF brand.
The designation of these bearings follows a clear scheme. In the 222 series, the first digit indicates the bearing type (spherical roller), the second the width and the last two the bore diameter. The EK suffix indicates a tapered bore (1:12) for mounting on an adapter sleeve, and C3 or C4 indicate the internal radial clearance, greater than normal. For example, 22205 EK/C3 has a tapered bore and C3 clearance, while 22209 EK/C4 has C4 clearance, which is looser. Knowing these suffixes is key to choosing the correct replacement.
These bearings are used in industries such as cement, mining, steel, paper and in aggregate processing plants. In Argentina, they are commonly found in conveyor belts, mills, vibrating screens, gearboxes and crushing equipment. Their ability to withstand misalignment makes them suitable for long shafts or assemblies where the base frame may deform. They are also used in industrial fans and large pumps.
To select the right bearing, take into account the radial and axial load, the rotation speed and the type of mounting. The tapered bore requires an adapter sleeve and a lock nut; the internal clearance is adjusted by measuring the reduction of radial clearance with feeler gauges. Lubrication can be with grease or oil, and sealing will depend on the environment: for dirty environments, choose variants with seals. Initial alignment must be careful, although the bearing tolerates subsequent misalignment.
As for equivalents, SKF spherical roller bearings are interchangeable with those of other brands that follow the same dimensional designation, such as FAG, NSK, NTN or Timken. However, always verify the clearance and bore suffixes, as they may vary between manufacturers. The 222 series is the most common for general applications; for higher loads, wider series are available. If you need help identifying the replacement, contact us.
If you already have the bearing part number, send it by WhatsApp to MR Accesorios Industriales and we will quote you promptly. We can also advise you if you need to define the clearance suffix or the bore type for your application. At MR we have the knowledge to help you choose the correct SKF bearing.

Frequently Asked Questions
- What are the dimensions of the SKF 22207 EK/C3 bearing?
- The SKF 22207 EK/C3 bearing has a 35 mm bore, a 72 mm outside diameter and a 23 mm width (35 x 72 x 23 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 22207.
- What does the EK suffix mean on an SKF bearing?
- The EK suffix indicates that the bearing has a tapered bore with a 1:12 taper. This allows it to be mounted on an adapter sleeve and the internal radial clearance to be adjusted with a lock nut. It is common in applications where simpler mounting is required or where shaft tolerances need to be compensated for.
- How do I choose between C3 and C4 clearance?
- C3 clearance is greater than normal and is used in applications with interference fits or high temperatures. C4 is even looser and is reserved for more severe conditions, such as high temperatures or speeds. The choice depends on the mounting and operating conditions; consult us if you have doubts.
- Are they interchangeable with other brands?
- Yes, SKF spherical roller bearings are interchangeable with those of other brands that share the same dimensional designation, such as FAG, NSK or NTN. However, verify the clearance and bore suffixes, because they may differ. It is always advisable to confirm dimensions and tolerances before replacing.
