Ang Spherical Roller Bearing 22215E is a popular bearing type designed to handle heavy radial loads, moderate axial loads, and misalignment. Here are its key specifications:
Basic Dimensions (ISO Standard)
Bore Diameter (d): 75 mm
Outer Diameter (D): 130 mm
Lapad ng katawan (B): 31 mm
Dynamic Load Rating (C): ~220 kN (varies by manufacturer)
Static Load Rating (C₀): ~245 kN (varies by manufacturer)
Speed Limit (Grease / Oil): Typically ~3,000 / 4,000 rpm (depends on lubrication)
Features of 22215E Designation
222 Series: Indicates a spherical roller bearing with a wider inner ring and higher load capacity than the 213 series.
15: Bore size (15 × 5 = 75 mm).
E: Enhanced internal design (optimized roller geometry and cage for higher load capacity).
Key Characteristics
✔ Self-Aligning: Compensates for shaft misalignment (up to ~2-3°).
✔ High Load Capacity: Suitable for heavy-duty applications.
✔ Robust Construction: Often includes a steel cage (may vary by manufacturer).
Common Applications
Industrial gearboxes
Mining & construction equipment
Pumps & compressors
Paper & steel mill machinery
