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

Products Description

The HV hanging spring vibration isolator is a professional suspension damping solution specially designed for overhead mechanical equipment and pipeline vibration control. Constructed with high-tensile heat-treated steel springs and reinforced metal housing, this hanger-style isolator delivers ultra-low natural frequency and outstanding vibration isolation performance, solving low-frequency vibration problems that ordinary rubber dampers cannot handle effectively.

Damping Structure & Corrosion Protection

Built with integrated damping structure, the HV hanging spring isolator efficiently suppresses spring resonance and bouncing during equipment operation. It perfectly absorbs vertical and horizontal vibration, cuts off vibration transmission of suspended pipelines, ventilation ducts, air conditioning units and ceiling-mounted machinery, and greatly reduces structural noise and resonance interference. All metal components undergo galvanized anti-corrosion treatment, featuring excellent rust resistance, oxidation resistance and weather adaptability for long-term use in humid, indoor and outdoor environments.

Flexible Adaptation & Broad Application

Featuring flexible load adaptation and easy installation, this suspended vibration isolator requires no complex construction and fits various overhead installation scenarios. It is widely applied to HVAC systems, suspended fans, air ducts, fire pipes, central air units and industrial suspended equipment. Effectively avoiding vibration fatigue damage, stabilizing equipment operation and lowering operational noise, the HV hanging spring isolator provides durable, high-efficiency vibration reduction and is an essential accessory for building electromechanical and industrial vibration control systems.
