Product Detail
Spherical Roller Bearing Spherical Roller Bearing KGUSuitable for heavy loads, limited misalignment, and lubrication through the housing
A reliable choice for industrial assemblies that require a double-row spherical roller bearing with standard dimensions and a lubrication path through the outer ring.
Introduction to the KGU 22236 CCW33 Spherical Roller Bearing
In heavy machinery, the shaft and its support must withstand considerable forces. In addition to radial loads, the assembly may also be exposed to axial loads, vibration, or a certain amount of misalignment between the shaft and housing. In such conditions, choosing the correct bearing type is just as important as selecting the right size.
The KGU 22236 CCW33 spherical roller bearing belongs to the family of double-row spherical roller bearings. The shape of its rollers and raceways allows this type of bearing to handle heavy radial loads and axial loads in both directions, within the applicable design limits. Its self-aligning structure can also compensate for a limited amount of angular misalignment; however, this feature does not replace proper alignment of the equipment.
In this model, the W33 suffix refers to an annular groove and lubrication holes in the outer ring. This feature can make it easier to supply lubricant from the housing to the inside of the bearing, provided that the housing lubrication system is compatible with it. The permissible load, operating speed, and allowable misalignment should be checked against the technical specifications of the KGU product.
The Meaning of 22236 CCW33 in Simple Terms
Each part of the code provides information about the bearing family and its design:
22236: This is the basic designation of the spherical roller bearing. In the common bearing numbering system, the final two digits, “36,” indicate a 180 mm bore diameter.
CC: This refers to the internal design of the bearing. Details such as the cage, guide ring, and internal components may be described slightly differently in the catalogs of different brands. The specifications of the KGU product should be used to confirm its exact internal design.
W33: In common bearing terminology, this refers to an annular groove and three lubrication holes in the outer ring. This feature alone does not mean that the bearing is self-lubricating or maintenance-free.
What Are the Standard Dimensions of a 22236 Spherical Roller Bearing?
Before placing an order, compare the three main dimensions with the equipment drawing or the previous bearing:
- Inside Diameter (d): 180 mm
- Outside Diameter (D): 320 mm
- Width (B): 86 mm
Note: Matching dimensions do not necessarily mean that all specifications are identical. When replacing check bearing, also check the bore type, internal clearance, load capacity, lubrication method, and suffixes of the previous bearing.
Features and Benefits of the 22236 CCW33 Spherical Roller Bearing
Suitable for Heavy Radial Loads
The two rows of spherical rollers make this bearing family suitable for applications involving considerable radial loads. The exact load capacity should be verified in the product catalog.
Axial Load Capacity in Both Directions
In addition to radial loads, spherical roller bearings can also accommodate axial loads in both directions. The permissible amount depends on the operating conditions and technical specifications.
Compensation for Limited Misalignment
The self-aligning design can reduce the effects of angular misalignment between the shaft and housing within the permitted design limits.
The W33 groove and lubrication holes allow lubricant to be supplied through the outer ring in assemblies equipped with a suitable lubrication path.
Standard Dimensions for Component Matching

Suitable for Industrial Equipment
When the load, speed, temperature, lubrication, and dimensions are compatible, this bearing family can be considered for various industrial shafts.
Common Applications of the 22236 Spherical Roller Bearing
Spherical roller bearings are used in equipment exposed to high loads or challenging installation conditions. The use of the 22236 size in any machine must be confirmed by checking the equipment drawing and performing the required technical calculations.
- Industrial Conveyor Systems: For shafts where load, environmental contamination, and lubrication conditions must be carefully evaluated.
- Mining Equipment and Crushers: In positions where the machine manufacturer specifies a spherical roller bearing with these characteristics.
- Steel and Cement Machinery: With special attention to temperature, contamination, load, and lubrication schedules.
- Large Fans and Rotating Equipment: Provided that the operating speed and installation method are compatible with the bearing specifications.
- Heavy-Duty Industrial Shafts: Wherever the dimensions, load capacity, and installation details match the equipment catalog.
Buying Guide for the KGU 22236 CCW33 Spherical Roller Bearing
To reduce the possibility of ordering the wrong part ordering the wrong part, do not rely only on the number 22236:
- Match the Complete Code: Compare 22236, the CC design, and the W33 feature with the previous bearing or the equipment parts list.
- Check the Bore Type: Bearings with cylindrical bores and bearings with tapered bores or other suffixes do not use the same installation method.
- Do Not Guess the Internal Clearance: If the equipment requires a specific clearance such as C3, it must be confirmed in the complete code or product specifications. W33 does not indicate C3 clearance.
- Inspect the Lubrication Path: The W33 feature is useful only when the housing and the lubrication method are compatible with it.
- Check Documentation and Authenticity: Compare the marking on the bearing, packaging, invoice, and declared technical specifications.
Important Installation Tips for the 22236 Spherical Roller Bearing
Even a bearing with the correct dimensions and specifications may fail prematurely if it is installed incorrectly. Use the equipment manufacturer's instructions and tools suitable for the bearing size as the basis for installation.
1) Inspect the Shaft and Housing
The seating surfaces must be clean and free from burrs, corrosion, or damage. The fit and installation method must match the equipment drawing.
2) Do Not Transfer Force Through the Rolling Elements
When mounting the bearing, the tool and applied force must correspond to the ring with the interference fit. Direct impact on the rollers or cage can cause damage.
3) Align the W33 Path with the Housing
4) Select the Correct Lubricant
Determine the lubricant type, quantity, and relubrication interval according to speed, load, temperature, and contamination conditions. Both insufficient and excessive lubrication can cause problems.
Maintenance and Condition Monitoring
- Monitor the Temperature: An unusual temperature increase may indicate a lubrication, loading, or installation problem.
- Pay Attention to Vibration and Noise: Any sudden change in the equipment's normal behavior should be investigated. Do not determine the cause of a failure based only on noise.
- Control Contamination: Water and solid particles can damage the lubricant and rolling surfaces. The condition of the assembly seals is important.
- Follow a Lubrication Schedule: W33 provides a path for lubricant entry, but it does not replace a regular lubrication program using the correct lubricant.
Signs That Inspection or Replacement May Be Required
Any of the following conditions does not necessarily confirm bearing failure, but it does make a technical inspection of the assembly necessary:
- A noticeable increase in vibration compared with the normal operating condition:9>
- Unusual, impact-like, or grinding noise from the shaft support area.
- An unusual increase in housing temperature.
- Severe lubricant contamination, discoloration, or the presence of metal particles.
- Excessive clearance, visible damage, or difficulty rotating the assembly.
