Bearing Pads

1. Description

Bearing Pads are high-performance components made of elastomeric materials like rubber or polyurethane, designed to provide support and vibration isolation in machinery, buildings, bridges, and other industrial structures. These pads act as shock absorbers, preventing vibrations and transferring loads effectively.

2. Specification

• Hardness: 60-90 Shore A
• Compression Strength: 15-30 MPa
• Temperature Resistance: -40°C to 100°C
• Max Load: 1000 kg per pad
• Thickness: 10mm – 50mm
• Density: 1.0 – 1.3 g/cm³

3. Working

Bearing pads work by cushioning the pressure and loads exerted on machinery or structures. They reduce the impact of dynamic forces, ensuring a longer lifespan for equipment and protecting against noise, vibration, and harsh impacts.

4. Principle

The principle behind bearing pads is the distribution of stress and strain across a surface while maintaining flexible cushioning properties. These pads absorb the force generated by machinery or structural movement, isolating the direct transmission of vibration to surrounding areas.

5. Assembly

1. Material Selection: Choose appropriate rubber/polyurethane for desired flexibility.
2. Cutting: Cut the material into the required dimensions.
3. Molding: Shape the bearing pad using compression molding techniques.
4. Quality Inspection: Perform tests for durability and compression strength.

6. Installation Process

1. Surface Preparation: Clean the surface where the bearing pads will be installed.
2. Placement: Position the pads on the prepared surfaces (under machinery or structural supports).
3. Alignment: Ensure correct alignment and adjust for proper load distribution.
4. Fixation: Secure the pads with appropriate fasteners or adhesives.

7. Technical Specification

• Compression Modulus: 10-15 MPa
• Hardness: 70 Shore A
• Tensile Strength: 12-18 MPa
• Elongation at Break: 200-350%
• Abrasion Resistance: Low

8. Troubleshooting

• Problem: Bearing pad compression failure.
  Solution: Check for excess weight or improper sizing.
