Detailed Description & Specifications
SKF6 Heavy-Duty Spring Vibration Isolator
Multi-Spring Vibration Mount for Industrial Machinery
The SKF6 Heavy-Duty Spring Vibration Isolator is an industrial spring isolation component designed to provide resilient support and help reduce mechanical vibration transmission from machinery and equipment.
Also known as a Multi-Spring Vibration Isolator, Heavy-Duty Spring Mount, or Industrial Spring Vibration Isolator, the SKF6 features six visible steel coil springs arranged within a rigid metal support frame.
Manufactured by Shanghai Songxia Vibration Absorber Co., Ltd., the SKF6 series is intended for machinery installations where equipment weight, load distribution, operating frequency, and spring deflection are important selection considerations.
Key Product Features
1. Six-Spring Isolation Configuration
The SKF6 features six coil springs arranged in two rows within a metal supporting structure.
The springs provide elastic support and distribute the applied equipment load across multiple spring elements.
The total load capacity and operating deflection depend on the selected spring characteristics and the complete isolator design.
2. Heavy-Duty Machinery Support
The multi-spring configuration can be designed to accommodate machinery requiring substantial support loads.
Actual load ratings should be confirmed using the manufacturer’s technical specifications.
3. Steel Frame Construction
The blue metal support frame provides a structural mounting arrangement around the spring assemblies.
Its open configuration also makes the spring layout visible for inspection.
4. Upper and Lower Mounting Plates
The SKF6 includes a broad upper plate and a lower base plate.
These components provide interfaces for compatible equipment and supporting structures.
5. Threaded Fastening Components
The upper assembly incorporates threaded fasteners and connection components.
The function and allowable adjustment range of each fastener should be confirmed from the relevant technical drawing and installation instructions.
6. Customized Spring Isolation Solutions
Spring stiffness, load capacity, operating deflection, mounting dimensions, and installation requirements can be evaluated according to customer specifications.
How Does the SKF6 Spring Vibration Isolator Work?
Industrial machinery produces dynamic forces through rotating imbalance, reciprocating movement, motor excitation, and other mechanical processes.
When equipment is rigidly installed on a foundation, these forces can be transmitted into supporting structures.
The SKF6 introduces spring compliance between the machinery and its support.
Under static loading, the springs compress and establish the operating position.
During operation, the spring system responds to dynamic forces and can reduce vibration transmission when its installed natural frequency is sufficiently below the dominant excitation frequency.
For a simplified single-degree-of-freedom system:
fn = (1 / 2π) × √(k / m)
Where:
- fn = Natural frequency (Hz)
- k = Equivalent spring stiffness (N/m)
- m = Supported mass (kg)
The actual vibration isolation performance depends on supported mass, spring stiffness, damping, excitation frequency, and installation conditions.
Typical Applications
Diesel Generator Sets
Spring vibration isolation for compatible generator sets and machinery bases requiring resilient support.
Industrial Pumps
Vibration isolation for suitable pump skids, motor-driven pumps, and pumping equipment assemblies.
Chillers and Refrigeration Equipment
Spring mounting solutions for compatible industrial chillers and refrigeration machinery.
Industrial Fans and Blowers
Resilient support for selected ventilation fans, centrifugal blowers, and air-moving machinery.
Air Handling Units
Spring vibration isolation for suitable large air handling units and HVAC mechanical equipment.
Heavy Machinery Bases
Multi-spring support for compatible industrial machinery platforms, equipment frames, and mechanical assemblies.
Benefits of SKF6 Multi-Spring Vibration Isolators
When properly selected and installed, the SKF6 can help:
- Reduce structure-borne vibration transmission.
- Provide resilient support for industrial machinery.
- Distribute supported loads across multiple spring elements.
- Accommodate selected heavy equipment mounting requirements.
- Provide an integrated steel-frame isolation assembly.
- Support customized load and deflection requirements.
Actual performance depends on verified product characteristics and the complete equipment installation.
SKF6 vs. SKF9 Spring Vibration Isolators
Both SKF6 and SKF9 feature multiple coil springs, steel support frames, and broad equipment mounting plates.
The SKF6 shown here incorporates six visible spring elements, while the SKF9 is another multi-spring configuration within the product family.
The appropriate model should be selected based on rated load, operating deflection, spring stiffness, installation dimensions, and required vibration isolation performance.
Neither model should be considered superior solely because of its spring quantity.
How to Select the Right SKF6 Spring Isolator
For accurate selection, customers should provide:
- Equipment type and model
- Total operating weight
- Number of required isolators
- Load distribution at each mounting point
- Equipment operating speed (RPM)
- Dominant vibration frequencies
- Required isolation efficiency
- Target spring deflection
- Available installation height
- Mounting plate dimensions and fixing details
- Equipment center of gravity
- Expected horizontal and transient forces
- Operating environment and temperature
Our technical team can review these parameters and assist with selecting a suitable spring vibration isolation solution.
Frequently Asked Questions
What is an SKF6 spring vibration isolator?
The SKF6 is a multi-spring industrial mounting component designed to provide resilient support and help reduce vibration transmission.
It features six visible coil springs arranged within a steel frame, together with upper and lower mounting plates.
What is the advantage of a six-spring vibration isolator?
A six-spring arrangement allows the applied load to be distributed across multiple elastic elements.
This provides flexibility in configuring the overall load capacity and stiffness, but the actual performance depends on the selected springs and complete structural design.
Is the SKF6 suitable for heavy machinery?
The SKF6 can be evaluated for machinery requiring substantial support loads. However, the actual suitability must be confirmed using the rated capacity, supported load per isolator, operating deflection, and installation conditions.
Can SKF6 spring isolators be used for generators?
Yes, the SKF6 series can be considered for compatible generator installations.
Selection requires the generator’s operating weight, mounting point loads, operating speed, allowable displacement, and foundation details.
How does spring deflection affect vibration isolation?
For an ideal linear spring under gravitational loading, greater static deflection corresponds to a lower natural frequency.
A simplified preliminary relationship is:
fn ≈ 15.8 / √δ
Where fn is in Hz and δ is static deflection in millimeters.
This relationship helps with preliminary selection, but actual performance should be verified using product data.
Can the SKF6 be customized?
Customization can be evaluated for spring characteristics, load capacity, operating deflection, mounting dimensions, and installation requirements.
Customers should provide equipment specifications and technical drawings for review.
