De Spherical Roller Bearing 22205 E is a specific type of bearing designed to handle heavy radial loads and moderate axial loads while accommodating misalignment. Here’s a detailed breakdown of its specifications and features:
1. Bearing Specifications:
Oantsjutting: 22205 E
222 Series: Indicates a spherical roller bearing with a bore diameter in the 05 size category.
05: Bore diameter = 25 mm (calculated as 05 × 5 = 25 mm).
E: Enhanced internal design (optimized roller geometry and material for higher load capacity).
Bore Diameter (d): 25 mm
Outer Diameter (D): 52 mm
Breedte (B): 18 mm
2. Key Features:
Self-Aligning Capability: Can tolerate shaft misalignment (typically up to 2-3°), making it suitable for applications where shaft deflection or mounting errors occur.
High Load Capacity: Designed for heavy radial loads and moderate axial loads in both directions.
Robust Construction: Features barrel-shaped rollers and two rows of rollers for better load distribution.
Cage Type: Usually comes with a stamped steel cage (E suffix) for durability.
3. Dynamic & Static Load Ratings (Approximate):
Dynamic Load Rating (C): ~48 kN (fariearret troch fabrikant).
Statyske Load Rating (C₀): ~32 kN (fariearret troch fabrikant).
4. Speed Wurdearrings:
Reference Speed: ~7,000 rpm (grease-lubricated).
Beheine snelheid: ~9,500 rpm (oil-lubricated).
5. Common Applications:
Yndustriële gearboxen
Mining & construction equipment
Papiermole masines
Pumps & compressors
Conveyor systems
6. Ekwivalint Bearings (Cross-Reference):
SKF: 22205 E
FAG / Wêr: 22205 E1 (may have slight design differences)
NSK: 22205 CE4
TIMKEN: 22205 EJ
7. Mounting & Lubrication:
Clearance: Typically CN (Normal clearance) útsein as oars oantsjutte.
Lubrication: Compatible with fet of oalje.
