How do I choose between spring, rubber and pneumatic vibration isolators?

Start with the disturbing frequency of your equipment. Isolation only begins when the disturbing frequency is more than 1.41 times the isolator's natural frequency, and a ratio of 3 or higher is recommended. Rubber mounts suit higher-speed, lighter equipment; spring isolators with a natural frequency of 3–5 Hz suit chillers, pumps, fans and generators; pneumatic air mounts reaching 1.7 Hz suit precision instruments and semiconductor tools.

What information is needed to size a vibration isolator?

Provide the equipment operating weight, center of gravity position, number and layout of support points, operating speed (RPM) or excitation frequency, installation type (floor-mounted or suspended), environment (indoor, outdoor, corrosive) and any seismic or wind restraint requirements. Bellking engineers return a vibration isolation plan within 24 hours.

How long do Bellking vibration isolators last?

Under normal operating conditions, Bellking spring and transformer isolators perform efficiently for more than 15 years, and pneumatic air-mount isolators for more than 6 years. Steel parts use a Dacromet coating that passes 900-hour salt spray testing.

Can Bellking manufacture custom, non-standard vibration isolators?

Yes. Bellking offers 1:1 customization based on actual equipment parameters, with customized solutions available in as little as 3 working days through a defined process: requirement communication, confirmation, solution design, solution approval and production.

What lead time, warranty and documentation do you provide?

Standard models can ship within 24 hours. All products come with a 1-year free warranty, installation manuals and technical guidance. Factory inspection reports and third-party test reports are available, and production is ISO 9001 certified.

Product Description

SWA is ideal for Heavy Duty Applications, commonly used in the Mining, Quarrying and Construction Industries. The mountings consist of a High Dynamic Rubber Compound sandwiched between multiple steel interleaf plates. This design allows the mountings to withstand large compressive forces with minimum deformation, whilst providing a relatively low stiffness in the shear direction. Multi-layer design to reduce deflection of mount under loads.

Frequently Asked Questions

What primary industries are SWA mountings designed for?

SWA mountings are explicitly engineered for heavy-duty applications, making them widely utilized across the mining, quarrying, and construction industries where durable vibration control is vital.

What materials are used to construct SWA mountings?

These mountings consist of a High Dynamic Rubber Compound bonded and sandwiched between multiple high-strength steel interleaf plates.

How does the multi-layer design benefit equipment performance?

The multi-layer configuration reduces the deflection of the mount under substantial working loads, ensuring greater mechanical stability and longevity for connected machinery.

How do SWA mountings perform under compression versus shear stress?

The structural composition enables the mountings to withstand large compressive forces with minimal deformation, while simultaneously offering relatively low stiffness in the shear direction.

Why is High Dynamic Rubber Compound used in this mount?

The High Dynamic Rubber Compound provides superior fatigue resistance and vibration attenuation, maintaining its structural integrity under continuous, heavy-duty cyclic loading.

What is the function of the steel interleaf plates?

The steel interleaf plates reinforce the rubber compound, restraining lateral expansion under high pressure and significantly increasing the overall vertical load-carrying capacity.
