CAT 132-7720 Engine Mount Cushion - Premium Replacement Part for Caterpillar Heavy Machinery

Engine mount cushions are critical vibration damping components in the engine mounting systems of heavy machinery. The CAT 132-7720 engine mount cushion is specifically designed for Caterpillar's heavy-duty construction equipment.

Technical Specifications and Material Composition

This engine mount cushion is manufactured from NBR (Nitrile Butadiene Rubber). As detailed on Wikipedia, NBR rubber is the preferred elastomer for industrial applications due to its oil and fuel resistance.

Physical Properties:

• Hardness: 70 ± 5 Shore A (per ASTM D2240 standard)
• Tensile Strength: Minimum 15 MPa
• Elongation at Break: 350% minimum
• Temperature Range: Continuous operation from -30°C to +100°C
• Oil Resistance: Maximum 30% volume change after 70 hours in ASTM No.3 oil at 70°C

Application Areas and Compatible Models

The CAT 132-7720 engine mount cushion is compatible with the following Caterpillar models:

• CAT 320C, 320D, 320E Series Excavators
• CAT D6R, D6T Series Dozers
• CAT 966H, 966K Series Loaders
• CAT 140H, 140K Series Graders

Vibration Damping Mechanism

Engine mount cushions operate on the principle of viscoelastic deformation. Vibration energy produced by the engine is converted to heat energy within the rubber's molecular structure, effectively damping vibrations. This results in:

1. Maximum operator comfort
2. Minimized metal fatigue on chassis and cabin
3. Prevention of vibration-related failures in electronic components
4. Increased overall machine efficiency
