Product Description

Rubber Dampers / Rubber Isolators

Rubber dampers (also known as rubber isolators) are mechanical components that utilize the high elasticity, damping, and internal friction properties of rubber to isolate vibrations, cushion shocks, and reduce noise. Their primary applications are as follows:

🔧 Primary Applications

1. Vibration Isolation

Preventing vibrations generated by operating machinery from transmitting to foundations or other structures:

Industrial Equipment: Anti-vibration pads/mounts for pumps, fans, compressors, diesel generator sets, and HVAC units.

Precision Equipment: Optical instruments, laboratory benches, and medical imaging equipment (CT/MRI scanners) to prevent ground vibrations from compromising accuracy.

Construction: Base isolation for equipment in building pump rooms and chiller plants to minimize structure-borne sound.

2. Shock Absorption (Impact Resistance)

Absorbing transient energy caused by startup, shutdown, or external impacts:

Rail Transit: Rubber chevron springs (rubber stack springs) between carbodies and bogies (primary/secondary suspension).

Automotive: Engine mounts (motor mounts), transmission mounts, and suspension bushings-absorbing road bumps and engine knock.

Construction Machinery: Cab mounts for excavators and shock pads under loader seats.

3. Noise Control

Utilizing the high damping characteristics of rubber to dissipate vibrational energy and reduce structure-borne noise:

HVAC Systems: Rubber flexible connectors at fan-duct connections.

Marine Industry: Mounting marine pumps and main engines via rubber isolators to reduce hull structure noise.

4. Displacement Compensation & Misalignment Correction

Allowing minor translational or rotational movement due to thermal expansion/contraction or installation errors:

Rubber hangers in piping support systems.

Elastic adjustment for equipment bases with slight unevenness or settlement.

🏭 Common Application Industries

✅ Characteristics of Rubber Dampers

Advantages: Low natural frequency, high damping (faster vibration decay than metal springs), combined vibration isolation and sound insulation, maintenance-free, available in various shapes.

Limitations: Performance constraints regarding temperature, oil, and ozone resistance (selection of NBR, CR, NR, Silicone, etc., required); susceptible to creep under long-term compression.
