Decoding SKF 22316 EK/C4
- 223Series
- Spherical roller bearings, 223 series. Series differ in outside diameter and width even when the bore is the same.
- 16Bore
- Bore 80 mm (16 × 5).
- EK/C4Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22316 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 22316 EK/C4 measures 80 mm across the bore and 170 mm across the outside diameter; its width is 58 mm (80 x 170 x 58 mm).

SKF spherical roller bearings handle combined radial and axial loads while tolerating shaft misalignment. Two rows of rollers run on a spherical outer raceway, so the shaft can deflect without adding stress inside the bearing. This makes them a practical choice for equipment where perfect alignment is difficult to maintain.
The part number tells you what you are getting. In the 222 series, the first digit identifies the bearing type, the second gives the width, and the final two digits indicate the bore diameter. Look at the suffixes: EK means a tapered bore with a 1:12 taper for an adapter sleeve, while C3 and C4 indicate internal radial clearance above normal. For instance, 22205 EK/C3 combines a tapered bore with C3 clearance, and 22209 EK/C4 has the looser C4 clearance. Reading these suffixes correctly is essential when ordering a replacement.
These bearings appear in cement, mining, steel, paper, and aggregate processing. Typical equipment includes conveyors, mills, vibrating screens, gearboxes, crushers, industrial fans, and large pumps. Misalignment tolerance suits long shafts and frames that may deform under load.
Selection depends on radial and axial load, speed, and mounting method. A tapered bore requires an adapter sleeve and lock nut, and you set internal clearance by measuring radial clearance reduction with feeler gauges. Grease or oil lubrication works, and seals should match the environment; dirty conditions call for sealed variants. Align carefully at installation, even though the bearing tolerates some misalignment afterward.
SKF spherical roller bearings interchange with other brands that follow the same dimensional designation, including FAG, NSK, NTN, and Timken. Always check clearance and bore suffixes, since they can differ between manufacturers. The 222 series covers most general applications; wider series are available for higher loads.

Frequently asked questions
- SKF 22316 EK/C4 bearing: what are its dimensions?
- SKF 22316 EK/C4 measures 80 mm across the bore and 170 mm across the outside diameter; its width is 58 mm (80 x 170 x 58 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22316.
- What does the EK suffix mean on an SKF bearing?
- EK indicates a tapered bore with a 1:12 taper. This allows mounting on an adapter sleeve, and you adjust internal radial clearance with a lock nut. It is common where simpler mounting is needed or shaft tolerances must be compensated for.
- How do I choose between C3 and C4 clearance?
- C3 clearance is greater than normal and suits 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 mounting and operating conditions; consult us if you have doubts.
- Are they interchangeable with other brands?
- Yes, SKF spherical roller bearings interchange with 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.
