SKF 23230 CC/W33 C3 150x270x96 mm - Spherical Roller Bearing

Technical Specifications

The dimensions 150x270x96 mm correspond to the 23230 bearing size.

Load ratings, operating speeds, and bearing mass should be confirmed for the exact SKF execution before being added to the published product specifications.

What Does SKF 23230 CC/W33 C3 Mean?

The designation identifies the bearing series, internal construction, lubrication arrangement, and radial internal clearance.

23230 - Bearing series and dimensions

The basic designation 23230 identifies a double-row spherical roller bearing with a bore diameter of 150 mm, an outside diameter of 270 mm, and a width of 96 mm.

The 232 series is designed to accommodate radial loads and axial loads acting in both directions.

Its spherical outer ring raceway provides self-aligning capability.

CC - SKF internal design

The CC suffix identifies an SKF design with symmetrical barrel-shaped rollers, window-type steel cages, and a guide ring positioned between the roller rows.

This arrangement supports combined radial and axial loading while allowing angular misalignment between the shaft and housing.

The CC suffix does not define C3 clearance or lubricant type.

W33 - Lubrication groove and holes

W33 specifies 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 identify an integrated seal or a specific lubricant.

C3 - Increased radial internal clearance

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

Increased clearance may be required where interference fits or temperature differences between bearing rings reduce clearance during installation and operation.

The selection of C3 clearance must be based on the operating conditions of the bearing arrangement.

A C3 bearing should not automatically be replaced by a normal-clearance variant.

Cylindrical bore

SKF 23230 CC/W33 C3 has a cylindrical bore with a nominal diameter of 150 mm.

The absence of the K suffix indicates that this is not the tapered-bore 1:12 execution.

Tapered-bore variants require a different mounting arrangement and are not directly interchangeable without checking the shaft design.

Construction and Operating Principle

SKF 23230 CC/W33 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 steel cages.

A guide ring is incorporated as part of the CC internal design.

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

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

The bearing has an open construction without integrated seals.

The surrounding bearing arrangement must provide suitable protection against contamination and moisture.

Lubrication of SKF 23230 CC/W33 C3

The W33 execution incorporates an annular lubrication groove and three lubrication holes in the outer ring.

This allows grease or oil to be supplied through the housing lubrication system.

The lubricant type, quantity, and relubrication interval depend on rotational speed, bearing load, operating temperature, and environmental conditions.

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

SKF 23230 CC/W33 C3 vs Other Variants

Bearings in the 23230 series may have identical nominal boundary dimensions of 150x270x96 mm while differing in bore configuration and radial internal clearance.

Cylindrical-bore and tapered-bore versions are not automatically interchangeable.

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

Alternative Designations and Reference Formats

Natural written variations include:

• SKF 23230 CC/W33 C3

• 23230 CC/W33 C3 SKF

• SKF 23230 CC/C3W33

• SKF23230CC/C3W33

The designation 23230 CC/C3W33 follows the standard SKF suffix grouping format.

Before treating both written formats as the same catalogue reference, verify the complete designation on the bearing packaging or in the manufacturer's documentation.

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

Bearing Selection and Interchangeability

Before purchasing SKF 23230 CC/W33 C3, verify the following technical characteristics:

• Boundary dimensions: 150x270x96 mm.

• Bore configuration: Cylindrical, 150 mm.

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

• Radial internal clearance: Increased C3.

• Cage: Window-type steel.

• Sealing: Open construction.

• Lubrication: W33 groove and three lubrication holes.

• Loads: Compatibility with the requirements of the bearing arrangement.

• Operating speed: Appropriate for the lubrication and temperature conditions.

• Mounting fits: Correct shaft and housing tolerances.

A bearing from another manufacturer with identical nominal dimensions is not necessarily fully interchangeable.

The internal design, load ratings, radial clearance, cage construction, and mounting requirements must also be compared.

Applications of SKF 23230 CC/W33 C3

Spherical roller bearings in the 232 series are intended for industrial rotating assemblies subjected to substantial radial loads, axial loads, and possible angular misalignment.

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

Increased C3 radial internal clearance may be relevant where interference fits or thermal effects reduce operating clearance.

These are general applications based on the construction of spherical roller bearings, not confirmed assignments of this exact SKF reference to specific machine models.

Installation and Operating Recommendations

Before installation, clean the shaft and housing surfaces and check their dimensions and condition.

When installing a ring with an interference fit, apply the mounting force to the ring being fitted. Do not transmit mounting forces through the rollers or raceways.

Account for the effect of interference fits on radial internal clearance and ensure correct axial location of the bearing rings.

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

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

Frequently Asked Questions - FAQ

No. It is an open bearing without integrated seals. Appropriate lubrication and protection against contamination must be provided by the bearing arrangement.

What is the load rating of SKF 23230 CC/W33 C3?

For the SKF 23230 CC/C3W33 execution, the basic dynamic load rating is reported as 1,129 kN and the basic static load rating as 1,460 kN. These values should only be assigned to the supplied product after confirming that the complete designations refer to the same SKF execution.

Can SKF 23230 CC/W33 C3 be replaced with a tapered-bore variant?

Not without checking the mounting arrangement. The CC version has a cylindrical bore, while the CCK version has a tapered bore. Identical nominal dimensions do not guarantee direct interchangeability.
