SKF 22216 E/C3 80x140x33 mm - Spherical Roller Bearing

Technical Specifications

The technical parameters correspond to SKF catalogue data for the specific designation 22216 E/C3.

Catalogue speed ratings are not guaranteed operating speeds under all conditions. Actual permissible speed depends on load, lubrication, temperature, and the complete bearing arrangement.

What Does SKF 22216 E/C3 Mean?

The designation identifies the bearing series, bore diameter, internal design, and radial internal clearance.

22216 - Bearing series and dimensions

The basic designation 22216 identifies a double-row spherical roller bearing with boundary dimensions of 80x140x33 mm.

The bearing incorporates two rows of rollers and a common spherical outer ring raceway, allowing it to accommodate angular misalignment.

E - Optimized SKF internal design

The E suffix identifies SKF's optimized spherical roller bearing internal design.

This construction incorporates symmetrical rollers and pressed steel cages, with internal geometry developed to increase load-carrying capacity.

The E suffix does not specify radial internal clearance, lubricant type, or operating temperature.

C3 - Increased radial internal clearance

The C3 suffix specifies radial internal clearance greater than normal (CN).

Increased initial clearance may be necessary when interference fits and temperature differences between the inner and outer rings reduce the available clearance during operation.

C3 does not automatically indicate a higher load rating or suitability for higher temperatures in every application.

The correct clearance must be selected according to the mounting fits, operating temperature, load, and required operating clearance.

No K suffix - Cylindrical bore

SKF 22216 E/C3 has a cylindrical bore with a nominal diameter of 80 mm.

The SKF 22216 EK/C3 variant has a tapered bore with a 1:12 taper.

This difference affects mounting procedures and the selection of associated shaft or adapter components.

Construction and Operating Principle

SKF 22216 E/C3 consists of an inner ring with two raceways, an outer ring with a common spherical raceway, two rows of symmetrical barrel-shaped rollers, and pressed steel cages.

The spherical outer ring raceway allows the inner ring and roller assembly to align at a limited angle relative to the housing.

This self-aligning capability helps compensate for shaft deflection and misalignment between the shaft and housing.

The two rows of rollers allow the bearing to accommodate substantial radial loads together with axial loads in both directions.

The bearing has an open construction without integrated seals.

Appropriate lubrication and protection against contamination must therefore be provided by the surrounding bearing arrangement.

Load Ratings and Operating Speeds

The SKF catalogue specifies the following performance parameters for 22216 E/C3.

The basic dynamic load rating is used in bearing life calculations under dynamic loading conditions.

The basic static load rating relates to resistance against permanent deformation under static loading conditions.

The fatigue load limit is used in SKF bearing life calculations.

Reference speed and limiting speed are catalogue values rather than guaranteed operating speeds under all conditions.

Actual permissible speed depends on lubrication, bearing load, operating temperature, heat generation, and the complete mounting arrangement.

Lubrication of SKF 22216 E/C3

SKF 22216 E/C3 incorporates lubrication features that allow lubricant to be supplied through the outer ring.

The catalogue dimensions of these features are:

The bearing is an open design without integrated contact seals.

The appropriate lubricant and relubrication interval must be selected according to the operating conditions.

Relevant factors include rotational speed, load, temperature, contamination, and the housing lubrication system.

The bearing designation does not specify a particular grease formulation or lifetime grease fill.

SKF 22216 E/C3 vs Other Variants

Different versions of the SKF 22216 series have identical nominal boundary dimensions but may differ in bore configuration or radial internal clearance.

All listed variants have nominal boundary dimensions of 80x140x33 mm.

However, identical dimensions do not mean that the bearings are directly interchangeable.

SKF 22216 E/C3 and SKF 22216 EK/C3 differ in bore geometry and mounting requirements.

Replacing SKF 22216 E/C3 with SKF 22216 E requires evaluation of the operating clearance, mounting fits, and thermal conditions.

Alternative Designations and Reference Formats

The following natural reference formats may be used to identify the bearing:

• SKF 22216 E/C3

• 22216 E/C3 SKF

• SKF22216E/C3

• SKF 22216E/C3

• 22216-E-C3 SKF

These are alternative commercial reference formats, not separate OEM part numbers. The manufacturer's original designation remains SKF 22216 E/C3.

Reported EAN/GTIN: 7316576652509.

No unverified OEM references or cross-manufacturer equivalents have been assigned.

Bearing Selection and Interchangeability

Before purchasing SKF 22216 E/C3, verify the complete bearing designation and the technical requirements of the application.

Important selection criteria include:

• Boundary dimensions: 80x140x33 mm.

• Bore configuration: Cylindrical, 80 mm.

• Internal design: SKF E.

• Radial internal clearance: C3, greater than normal.

• Mounting fits: Their effect on radial internal clearance.

• Load requirements: Radial and axial loading conditions.

• Operating speed: Compatibility with lubrication and temperature.

• Thermal conditions: The effect of temperature differences between the rings on operating clearance.

• Angular misalignment: Within the manufacturer's permissible limits.

• Lubrication: Appropriate grease or oil and adequate lubricant supply.

• Housing arrangement: Suitable fits, support surfaces, and protection against contamination.

Bearings from different manufacturers may share the same nominal dimensions but differ in internal geometry, cage design, load ratings, and operating characteristics.

Identical dimensions alone do not guarantee full technical interchangeability.

Applications of SKF 22216 E/C3

Double-row spherical roller bearings are designed for rotating assemblies requiring substantial radial load capacity and the ability to accommodate angular misalignment.

Typical applications for this bearing category include industrial shaft supports, mechanical power transmission systems, and bearing arrangements subjected to shaft deflection.

The C3 clearance configuration may be appropriate for applications in which mounting fits and thermal conditions require greater initial radial internal clearance.

However, C3 is not automatically suitable for every high-temperature or heavily loaded application.

These are general applications based on the bearing design.

They do not establish that the exact SKF 22216 E/C3 designation is approved for a particular machine, gearbox, motor, or OEM assembly.

Suitability must be confirmed against the equipment specifications and actual operating conditions.

Installation and Operating Recommendations

Preparation

Before installation, clean the shaft, housing, and bearing mounting surfaces.

Check the dimensions, fits, and condition of all mating components.

Mounting

When mounting the bearing with an interference fit, apply the mounting force to the ring being fitted.

Do not transmit mounting forces through the rollers or raceways.

Use appropriate mounting tools and follow SKF's recommended procedures for cylindrical-bore spherical roller bearings.

Internal clearance

Consider the reduction in radial internal clearance caused by interference fits.

The remaining operating clearance must be suitable for the bearing load, speed, and temperature conditions.

Lubrication and operation

Provide the lubricant specified for the application.

Ensure adequate lubricant distribution and protection against contamination.

During operation, monitor bearing temperature, vibration, and lubrication condition as appropriate.

Storage

Store the bearing in its original packaging in a clean, dry environment.

Protect it against moisture, contamination, impacts, and mechanical damage.
