Detailed Description & Specifications
SKF2 Damped Spring Vibration Isolator
Dual-Spring Vibration Mount for Industrial Machinery
The SKF2 Damped Spring Vibration Isolator is an industrial spring mounting component designed to provide resilient equipment support and reduce the transmission of mechanical vibration.
Also known as a Dual-Spring Vibration Isolator, Two-Spring Vibration Mount, or Industrial Damped Spring Isolator, the SKF2 features a compact steel support frame, spring isolation elements, a textured upper mounting plate, and a lower fixing base.
Manufactured by Shanghai Songxia Vibration Absorber Co., Ltd., the SKF2 series is intended for machinery installations where operating weight, spring deflection, mounting dimensions, and vibration isolation requirements must be considered together.
Key Product Features
1. Dual-Spring Isolation Design
The SKF2 incorporates a two-spring configuration designed to provide elastic support for compatible machinery installations.
The spring elements compress under static loading and respond to dynamic forces generated during equipment operation.
The actual load capacity and operating deflection depend on the selected spring characteristics.
2. Damped Spring Vibration Control
The SKF2 is classified as a damped spring vibration isolator.
Spring compliance helps reduce vibration transmission, while the damping arrangement is intended to control oscillatory response, particularly near resonance and during equipment startup and shutdown.
The specific damping mechanism should be confirmed from the product’s technical specifications.
3. Compact Steel Support Frame
The blue steel frame provides an integrated structural arrangement for the spring assemblies.
Its compact configuration can be useful for machinery installations with limited mounting space.
4. Textured Upper Mounting Plate
The broad black upper plate features a textured surface and a central fastening component.
It provides an equipment support interface for suitable machinery mounting arrangements.
5. Base Plate with Fixing Holes
The lower mounting base incorporates fixing holes for attachment to a suitable foundation or supporting structure.
6. Customizable Spring Isolation Solutions
Spring stiffness, rated load, operating deflection, mounting dimensions, and installation requirements can be evaluated according to customer specifications.
How Does the SKF2 Spring Vibration Isolator Work?
Industrial machinery generates dynamic forces through rotating imbalance, motor excitation, reciprocating motion, and other mechanical processes.
When equipment is rigidly connected to its supporting structure, these forces can be transmitted into floors, frames, and surrounding machinery.
The SKF2 introduces spring compliance between the equipment 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 the installed natural frequency is sufficiently below the dominant excitation frequency.
Damping helps control motion near resonance and during transient operating conditions.
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)
Actual vibration isolation performance depends on spring stiffness, supported mass, damping characteristics, excitation frequency, and installation conditions.
Typical Applications
Industrial Water Pumps
Spring vibration isolation for compatible centrifugal pumps, circulation pumps, and motor-driven pumping equipment.

Spring mounting solutions for suitable chillers and mechanical cooling equipment.
Electric Motors
Resilient support for selected electric motors and motor-driven machinery assemblies.
Industrial Machinery Bases
Spring vibration isolation for compatible equipment frames, machinery skids, and industrial mechanical installations.
Benefits of SKF2 Damped Spring Vibration Isolators
When properly selected and installed, SKF2 isolators can help:
- Reduce structure-borne vibration transmission.
- Provide resilient support for industrial equipment.
- Distribute the supported load across two spring elements.
- Control oscillatory response through damping.
- Offer a compact industrial mounting arrangement.
- Support customized load and deflection requirements.
Actual performance depends on verified product specifications and operating conditions.
SKF2 vs. SKF4, SKF6 and SKF9 Spring Isolators
The SKF2, SKF4, SKF6, and SKF9 belong to the multi-spring vibration isolator product family.
SKF2: Two-spring configuration.
SKF4: Four-spring configuration.
SKF6: Six-spring configuration.
SKF9: Nine-spring configuration.
Spring quantity provides a structural distinction between the models, but it does not independently determine rated load or vibration isolation efficiency.
Selection should be based on verified load capacity, spring stiffness, operating deflection, mounting dimensions, and project requirements.
How to Select the Right SKF2 Spring Isolator
For accurate selection, customers should provide:
- Equipment type and model
- Total operating weight
- Number of required mounting points
- Load at each mounting point
- Equipment operating speed (RPM)
- Dominant vibration frequencies
- Required isolation performance
- 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 configuration.
Frequently Asked Questions
What is an SKF2 damped spring vibration isolator?
The SKF2 is an industrial vibration isolation component featuring a dual-spring configuration, steel support frame, upper mounting plate, and lower fixing base.
It is designed to provide resilient machinery support and help reduce vibration transmission when correctly selected.
What is the advantage of a dual-spring vibration isolator?
A dual-spring arrangement distributes the applied load across two elastic elements.
This provides flexibility in configuring the overall load capacity and stiffness while maintaining a compact mounting arrangement.
Actual performance depends on the spring characteristics and complete isolator design.
Can SKF2 spring isolators be used for industrial pumps?
The SKF2 can be evaluated for suitable industrial pump installations.
Selection should consider pump operating weight, motor speed, mounting loads, connected piping forces, and required vibration isolation performance.
Are SKF2 spring mounts suitable for ventilation fans?
The SKF2 series can be considered for compatible ventilation fans and blowers.
The selected isolator must provide sufficient load capacity and appropriate operating deflection for the equipment.
How does spring deflection affect vibration isolation?
For an ideal linear spring under static gravitational loading, greater 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.
Actual isolation performance must also account for excitation frequency, damping, and installation conditions.
Does damping always improve isolation efficiency?
Not necessarily. Damping helps reduce resonant amplification and control transient movement, but additional damping may increase transmitted vibration at certain frequencies above resonance.
The appropriate damping level depends on the equipment’s operating conditions and isolation objectives.
Can SKF2 spring vibration isolators be customized?
Customization can be evaluated for spring stiffness, rated load, operating deflection, mounting dimensions, and installation requirements.
Customers should provide equipment specifications and technical drawings for review.
