The Spherical Roller Bearing 22348 CC/W33 is a robust bearing designed to handle heavy radial loads, moderate axial loads, and misalignment. Here’s a detailed breakdown of its specifications and features:
Key Specifications:
Bearing Type: Spherical Roller Bearing (Self-aligning, double row)
Designation: 22348 CC/W33
22348: Indicates the bearing series and size (223 = spherical roller, 48 = bore diameter code).
CC: Internal design with enhanced roller guidance and optimized contact geometry.
W33: Indicates a lubrication groove and three oil holes in the outer ring.
Dimensions (Standard ISO):
Bore Diameter (d): 240 milimetr
Outer Diameter (D): 500 milimetr
Šířka (B): 155 milimetr
Dynamic Load Rating (C): ~2,500 kN (varies by manufacturer)
Static Load Rating (C₀): ~3,600 kN (varies by manufacturer)
Speed Rating (Grease / Oil): Depends on lubrication but typically up to ~800 rpm (grease) or ~1,000 rpm (oil).
Features & Benefits:
Self-Aligning Capability: Compensates for shaft misalignment (up to ~1.5–2.5°), reducing stress on the bearing.
Heavy-Duty Construction: Handles high radial and axial loads in both directions.
Enhanced Lubrication (W33): The groove and oil holes improve lubrication distribution, extending service life.
CC Design: Improved roller guidance for better load distribution and reduced friction.
Common Applications: Used in heavy machinery, mining equipment, gearboxes, paper mills, and industrial fans.
Equivalent Bearings (Cross-Reference):
Moderátor: 22348 CCK/W33
FAG/NSK/NTN: Similar designations (may vary slightly by internal clearance or cage material).
Timken: Often labeled under the same 22348 series.
Mounting & Maintenance Tips:
Use proper tools (induction heaters for mounting).
Ensure correct lubrication (grease or oil, depending on application).
Monitor for vibration/noise to detect early wear.
