SKF 23222 CCK/C3W33 110x200x69.8 mm - Spherical Roller Bearing

Technical Specifications

The nominal boundary dimensions are 110x200x69.8 mm.

The tapered bore and C3 radial internal clearance are essential characteristics of this specific SKF bearing designation.

Bearing Dimensions and Mounting Data

The nominal bore diameter is measured at the specified reference position of the tapered bore.

The bearing requires a compatible tapered shaft seating or an appropriately selected adapter or withdrawal sleeve.

The mounting procedure must account for the reduction in radial internal clearance as the bearing is driven onto the tapered seating.

What Does SKF 23222 CCK/C3W33 Mean?

The complete designation identifies the bearing series, internal design, bore configuration, radial internal clearance, and lubrication arrangement.

23222 - Bearing series and dimensions

The basic designation 23222 identifies a double-row spherical roller bearing with a nominal bore diameter of 110 mm.

The 232 series is designed to accommodate substantial radial loads, axial loads in both directions, and angular misalignment between the shaft and housing.

For SKF 23222 CCK/C3W33, the nominal boundary dimensions are 110x200x69.8 mm.

CC - SKF internal design

The CC suffix identifies an SKF spherical roller bearing design incorporating two rows of symmetrical barrel-shaped rollers, two pressed steel window-type cages, and a guide ring positioned between the roller rows.

The internal construction allows the bearing to accommodate combined radial and axial loads while maintaining self-aligning capability.

CC does not indicate increased radial internal clearance. Clearance is specified separately by the C3 designation.

K - Tapered bore with a 1:12 taper

The K suffix specifies a tapered bore with a taper ratio of 1:12.

SKF 23222 CCK/C3W33 can be mounted on a suitably prepared tapered shaft seating or by using an appropriate mounting sleeve.

As the bearing is driven axially onto the tapered seating, the inner ring expands and the radial internal clearance decreases.

Correct installation therefore requires monitoring axial drive-up or the reduction in radial internal clearance according to SKF mounting procedures.

C3 - Increased radial internal clearance

C3 identifies radial internal clearance greater than the normal CN clearance group.

Increased clearance may be required where interference fits, temperature differences between bearing rings, or other operating conditions reduce the clearance during installation or operation.

For a tapered-bore spherical roller bearing, the reduction in clearance during mounting is particularly important.

C3 does not define axial clearance, precision class, or lubricant type.

W33 - Lubrication groove and holes

W33 identifies an annular lubrication groove and three lubrication holes in the outer ring.

These features allow lubricant to be supplied through a suitably designed bearing housing.

W33 does not indicate an integrated seal or a particular grease formulation.

SKF Explorer

SKF 23222 CCK/C3W33 belongs to the SKF Explorer range.

SKF Explorer is a manufacturer-defined performance classification associated with bearing design, manufacturing processes, and operating performance.

It is not an additional suffix in the designation.

Construction and Operating Principle

SKF 23222 CCK/C3W33 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.

A guide ring is positioned between the roller rows as part of the CC internal design.

The spherical geometry of the outer ring raceway enables the bearing to compensate for angular misalignment between the shaft and housing, as well as shaft deflection within the manufacturer's permissible limits.

The two rows of rollers accommodate substantial radial loads together with axial loads acting in both directions.

Unlike the cylindrical-bore version, SKF 23222 CCK/C3W33 has a tapered bore. This affects the mounting method and the control of radial internal clearance after installation.

The bearing has an open construction without integrated seals.

Load Ratings and Operating Performance

The basic dynamic load rating is used to calculate bearing fatigue life under dynamic loading conditions.

The basic static load rating is used to evaluate resistance to permanent deformation under static loading.

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

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

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

SKF Load Calculation Factors

These factors are used when calculating equivalent bearing loads under combined radial and axial loading.

The applicable factor depends on the relationship between axial and radial forces and the calculation method used.

Lubrication of SKF 23222 CCK/C3W33

The bearing incorporates an annular lubrication groove and three lubrication holes in the outer ring.

The lubrication groove width is 8.3 mm, and the lubrication hole diameter is 4.5 mm.

The W33 arrangement allows grease or oil to be supplied through a compatible housing lubrication system.

Because the bearing has an open construction, the surrounding bearing arrangement must provide protection against contamination and moisture.

The lubricant type, quantity, and relubrication interval must be selected according to bearing load, rotational speed, operating temperature, and environmental conditions.

The W33 suffix does not indicate that the bearing is factory-filled with grease for its entire service life.

SKF 23222 CCK/C3W33 vs Other Variants

Different SKF 23222 variants may have identical nominal boundary dimensions but differ in bore configuration or radial internal clearance.

The listed variants have nominal boundary dimensions of 110x200x69.8 mm.

However, their bore geometry or radial internal clearance differs.

SKF 23222 CCK/C3W33 is not automatically interchangeable with SKF 23222 CC/C3W33.

The CCK version has a tapered bore, whereas the CC version has a cylindrical bore.

Replacing C3 clearance with normal CN clearance also requires verification of mounting and operating conditions.

Alternative Designations and Reference Formats

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

• SKF 23222 CCK/C3W33

• 23222 CCK/C3W33 SKF

• SKF23222CCK/C3W33

• SKF 23222CCK/C3W33

• 23222 CCK C3 W33 SKF

The manufacturer's original designation is SKF 23222 CCK/C3W33.

These alternative written formats do not represent separate OEM part numbers.

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

Bearing Selection and Interchangeability

Before purchasing SKF 23222 CCK/C3W33, verify the complete designation and the technical requirements of the bearing arrangement.

Important selection criteria include:

• Boundary dimensions: 110x200x69.8 mm.

• Bore configuration: Tapered, with a 1:12 taper.

• Internal design: Double-row, self-aligning SKF CC.

• Radial internal clearance: Increased C3.

• Cage: Pressed steel.

• Sealing: Open construction without integrated seals.

• Lubrication: W33 groove and three lubrication holes.

• Load requirements: Magnitude and direction of radial and axial forces.

• Operating speed: Compatibility with bearing load, lubrication, and temperature.

• Mounting: Compatibility with the tapered shaft seating or mounting sleeve.

• Residual clearance: Correct clearance after mounting.

When evaluating an equivalent bearing from another manufacturer, compare not only the nominal dimensions but also the internal design, load ratings, radial clearance, cage construction, and lubrication arrangement.

Identical boundary dimensions do not guarantee full interchangeability.

Applications of SKF 23222 CCK/C3W33

Spherical roller bearings in the 232 series are intended for industrial rotating assemblies requiring substantial radial load capacity and the ability to accommodate angular misalignment.

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

The tapered bore allows the use of suitable mounting arrangements, including bearing sleeves.

Increased C3 radial internal clearance may be relevant where mounting conditions or thermal effects reduce operating clearance.

These are general applications based on the bearing's construction.

They do not establish that the exact SKF 23222 CCK/C3W33 designation is approved for a particular machine, gearbox, motor, or OEM assembly.

Installation and Operating Recommendations

Preparation

Before installation, check the cleanliness and condition of the shaft, housing, and mounting components.

Verify the shaft dimensions, housing fits, and compatibility of the tapered seating or mounting sleeve.

Tapered-bore mounting

When installing the bearing on a tapered seating, monitor the reduction in radial internal clearance as the bearing is driven axially into position.

Excessive axial drive-up may reduce the internal clearance beyond the permissible limit.

Follow SKF mounting procedures for tapered-bore spherical roller bearings.

Mounting forces

Do not transmit mounting forces through the rollers or raceways.

Use appropriate tools and apply mounting forces according to the bearing and mounting arrangement.

Lubrication

Provide suitable lubrication through the bearing housing and W33 lubrication features where applicable.

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

Operation and storage

During operation, monitor temperature, vibration, and lubrication condition.

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

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