Sferni valjkasti ležajevi

The 22224E C3 buričasti ležaj is a specific type of bearing designed to handle heavy radial loads and moderate axial loads. Here’s a breakdown of its key features and specifications:

Key Features:

1. Type: Sferni roler ležaj
   • Spherical roller bearings are self-aligning, meaning they can accommodate misalignment between the shaft and housing, which is useful in applications where shaft deflection or mounting errors may occur.
2. Series: 22224
   • The “22224” indicates the bearing’s size and dimensions. It belongs to the 22200 series, which is a common series for spherical roller bearings.
3. E Design:
   • The “E” in the designation typically refers to an optimized internal design with a larger roller diameter and improved material, which enhances the load-carrying capacity and fatigue life of the bearing.
4. C3 Clearance:
   • The “Ц3” indicates the internal clearance of the bearing. C3 clearance is greater than standard (CN) clearance, making it suitable for applications where thermal expansion or other factors might cause the bearing to tighten up during operation.
5. Dimenzije:
   • The standard dimensions for a 22224 bearing are:
     • Bore Diameter (d): 120 Mm
     • Outer Diameter (D): 215 Mm
     • Širina (B): 58 Mm
6. Load Capacity:
   • Spherical roller bearings are known for their high radial load capacity and ability to handle axial loads in both directions. The exact load ratings (dynamic and static) can be found in manufacturer catalogs.
7. Applications:
   • These bearings are commonly used in heavy-duty applications such as:
     • Industrial gearboxes
     • Mining equipment
     • Paper mill machinery
     • Wind turbines
     • Pumps and compressors

Maintenance and Lubrication:

• Proper lubrication is critical for the performance and longevity of spherical roller bearings. The type of lubricant (grease or oil) and the lubrication interval depend on the operating conditions (speed, temperature, and load).
• Regular inspection and maintenance are recommended to ensure optimal performance.

Installation:

• Spherical roller bearings should be installed with care to avoid misalignment or damage. Proper mounting tools and techniques should be used.
