Product Description
130.45.2500 Triple Row Roller Slewing Bearing
The 130.45.2500 is a large Three Row Roller Slewing Rings Toothless bearing with boundary dimensions of 2279 mm × 2721 mm × 231 mm and a net weight of 3000 kg. Its three-row raceway design allows it to independently bear axial and radial loads as well as tilting moments, delivering the strongest load-bearing capacity in a robust and reliable structure.
Key features
- Three row cylindrical roller combined slewing bearing, no gear (toothless)
- Raceway hardness HRC 55-62 for long service life
- Static radial load rating C0r: 3020 kN
- Static axial load rating C0a: 25800 kN
- Cage: plastic or nylon
- Seal: double seal, NBR (Nitrile Butadiene Rubber)
- Rolling element material: GCr15; ring material: 50Mn or 42CrMo
- Precision class: P0, P6, P5
- Operating temperature: -30 °C to 100 °C
Mounting and structure dimensions
- D1: 2655 mm
- D2: 2345 mm
- n: 72 mounting holes, Ø 33 mm
- n1: 8 lubricating holes
- H1: 219 mm
- h: 54 mm
Applications
Suitable for heavy rotating parts with ultra-large axial loads, overturning moments and large radial loads, such as tunnel boring machines, port cranes and ladle turrets. The advanced double seal design reduces friction and wear, enhances load-bearing rigidity, and suppresses vibration and noise, significantly extending equipment service life under complex working conditions.
