22208 CW33 MGK 40x80x23 Spherical Roller Bearing

22208 CW33 MGK is a double-row spherical roller bearing with dimensions 40x80x23 mm. It has a 40 mm cylindrical bore, 80 mm outside diameter and 23 mm width. The bearing has a steel cage, normal internal clearance and an open design without integral seals.

22208 CW33 MGK - Product Characteristics

The 22208 CW33 uses two rows of spherical rollers operating against a common spherical raceway in the outer ring.

Its technical identification is:

22208 CW33 -> MGK -> spherical roller bearing -> double row -> cylindrical bore -> 40x80x23 mm

The spherical outer-ring raceway gives this bearing design its self-aligning capability, allowing it to accommodate a degree of angular misalignment between the shaft and housing.

Dimensions

The confirmed dimensions of 22208 CW33 MGK are:

d - Bore Diameter: 40 mm
D - Outside Diameter: 80 mm
B - Bearing Width: 23 mm
Dimensions: 40x80x23 mm
Mounting Chamfer: 1.1 mm
Mass: approximately 0.520 kg

For this bearing, the commercial dimensional notation 40x80x23 mm corresponds to d x D x B.

Double-Row Spherical Roller Construction

22208 CW33 MGK contains two rows of barrel-shaped rollers.

The rollers operate between the inner-ring raceways and a common spherical raceway in the outer ring. This geometry allows the inner ring, roller assembly and shaft to align angularly relative to the outer ring.

This construction distinguishes a spherical roller bearing from conventional rigid radial bearing designs.

Self-Aligning Capability

A defining characteristic of the 22208 CW33 design is its ability to accommodate a degree of angular misalignment between the shaft and housing.

This capability results from the spherical geometry of the outer-ring raceway rather than from additional adjustment components.

The exact permissible misalignment angle for the MGK version has not been confirmed in manufacturer documentation, so no numerical angular value is assigned here.

Radial and Axial Loads

The spherical roller bearing construction is designed to accommodate radial loads together with axial loads acting in either direction.

Its two rows of rollers provide rolling contact on both sides of the bearing centreline, while the spherical raceway geometry allows the bearing to combine load-carrying capability with self-alignment.

Specific Cr and C0r ratings are not stated here, because verified MGK manufacturer data for these values were not available. Ratings from SKF, FAG, NTN or another manufacturer should not automatically be assigned to the MGK product.

Cylindrical Bore

22208 CW33 MGK has a cylindrical 40 mm bore.

This is an important selection parameter because spherical roller bearings from the 22208 dimensional family can also be produced with tapered bores.

A tapered-bore version is normally identified by an additional K suffix. Therefore, the bore configuration must be checked rather than selecting a bearing solely from the base designation 22208.

Steel Cage

The available product data for 22208 CW33 MGK identify a:

Cage Material: Steel
Cage Guidance: Rolling elements

The cage separates and guides the two rows of spherical rollers during operation.

Because cage designs can vary between bearing manufacturers, this characteristic should be checked when evaluating a technically equivalent bearing from another brand.

Internal Clearance

The exact 22208 CW33 MGK version has normal internal clearance.

This distinction is important because 22208 CW33C3 MGK is a separate variant with increased C3 internal clearance.

Therefore:

22208 CW33 MGK - normal internal clearance
22208 CW33C3 MGK - C3 internal clearance

The C3 suffix should not be added to the current product designation.

Open Bearing Design

The bearing is supplied as an open spherical roller bearing without integral seals.

The lubrication and sealing arrangement must therefore be considered as part of the complete bearing installation rather than assuming that the bearing itself provides integrated contact seals.

Meaning of CW33

The complete designation 22208 CW33 should be retained when identifying and ordering this MGK bearing.

Available product data associate the C element with its steel cage configuration and W33 with the bearing's lubrication arrangement.

Because an official MGK suffix dictionary for this exact product was not available for verification, the complete CW33 suffix is preserved without assigning additional manufacturer-specific meanings that cannot be confirmed.

22208 CW33 vs 22208 CW33C3

These references should not be merged.

22208 CW33 MGK has normal internal clearance, whereas 22208 CW33C3 MGK incorporates increased C3 internal clearance.

Although their principal dimensions can both be 40x80x23 mm, the difference in internal clearance is technically significant when selecting a bearing for a specific installation.

Keeping the two references separate also prevents search engines and AI systems from incorrectly associating C3 specifications with the standard-clearance product.

Selection and Interchangeability

A replacement for 22208 CW33 MGK should not be selected solely because another bearing has dimensions of 40x80x23 mm.

The comparison should include:

• 22208 bearing series
• 40 mm cylindrical bore
• 80 mm outside diameter
• 23 mm width
• double-row spherical roller construction
• normal internal clearance
• cage design
• W33 configuration
• dynamic and static load ratings of the candidate bearing
• speed ratings
• lubrication requirements

An identically sized 22208 bearing from another manufacturer is therefore not automatically a fully equivalent replacement.

FAQ

What are the dimensions of 22208 CW33 MGK?

The bearing measures 40x80x23 mm, corresponding to d = 40 mm bore diameter, D = 80 mm outside diameter and B = 23 mm width.

What type of bearing is 22208 CW33 MGK?

It is a double-row spherical roller bearing, designed with spherical rollers and a common spherical outer-ring raceway.

Is 22208 CW33 MGK self-aligning?

Yes. The spherical outer-ring raceway gives this bearing construction self-aligning capability and allows it to accommodate a degree of angular misalignment.

Does 22208 CW33 MGK have a cylindrical or tapered bore?

This version has a 40 mm cylindrical bore. A tapered-bore variant would normally carry an additional K designation.

Does 22208 CW33 MGK have C3 clearance?

No. The exact 22208 CW33 MGK version has normal internal clearance. 22208 CW33C3 MGK is the separate C3 variant.

What loads can a spherical roller bearing accommodate?

Does 22208 CW33 MGK have seals?

No. It is an open bearing without integral seals.

Can another brand of 22208 CW33 replace the MGK bearing?

Not based on dimensions alone. Bore configuration, internal clearance, cage, W33 design, load ratings, speed limits and installation requirements should also be compared.
