Detailed Description & Specifications
SKA Damped Spring Vibration Isolator
Enclosed Spring Vibration Mount for Industrial Machinery and HVAC Equipment
The SKA Damped Spring Vibration Isolator is an industrial vibration isolation component designed to provide resilient equipment support and help reduce the transmission of mechanical vibration.
Also known as a Damped Spring Mount, Enclosed Spring Vibration Isolator, or Industrial Spring Vibration Mount, the SKA series combines spring-based isolation with a damping arrangement for suitable machinery installations.
Manufactured by Shanghai Songxia Vibration Absorber Co., Ltd., the SKA series is intended for mechanical equipment applications where vibration control, installation dimensions, operating loads, and isolation performance must be considered together.
Key Product Features
1. Enclosed Spring Isolation Design
The SKA features a compact cylindrical housing that accommodates its vibration isolation assembly.
The enclosed design provides a practical configuration for selected industrial machinery and HVAC equipment installations.
2. Spring-Based Vibration Isolation
The internal spring system provides elastic support and allows deflection under equipment load.
When properly selected, the spring stiffness and supported mass establish a natural frequency that can help reduce vibration transmission during equipment operation.
3. Damping for Vibration Control
The SKA is designed as a damped spring vibration isolator.
Damping helps control excessive motion near resonance and during transient operating conditions, including equipment startup and shutdown.
The specific damping mechanism and performance should be confirmed using the relevant technical specifications.
4. Compact Cylindrical Housing
The blue cylindrical housing provides an integrated structure for the isolation assembly.
Its compact profile makes the SKA suitable for consideration in installations where mounting dimensions are important.
5. Upper Equipment Mounting Interface
The upper section includes a circular mounting pad with a central hole.
This provides a connection interface for compatible equipment mounting arrangements.
6. Circular Base with Fixing Openings
The circular bottom base incorporates mounting openings for securing the isolator to a suitable supporting structure.
The fixing method should be selected according to the equipment and installation requirements.
How Does the SKA Damped Spring Vibration Isolator Work?
Industrial machinery generates dynamic forces through rotating imbalance, motor excitation, reciprocating motion, and other operating conditions.
When equipment is rigidly installed on a foundation, these forces can be transmitted into floors, building structures, and adjacent machinery.
The SKA introduces spring compliance between the equipment and its support.
Under static loading, the spring system compresses and establishes the operating deflection.
During equipment operation, the spring responds to dynamic forces and can reduce vibration transmission when the installed natural frequency is sufficiently below the dominant excitation frequency.
Damping helps control the response near resonance and during transient operating conditions.
For a simplified single-degree-of-freedom vibration isolation system:
fn = (1 / 2π) × √(k / m)
Where:
- fn = Natural frequency (Hz)
- k = Equivalent spring stiffness (N/m)
- m = Supported mass (kg)
Actual isolation performance depends on the supported load, dynamic stiffness, damping ratio, excitation frequency, and installation conditions.

Benefits of SKA Damped Spring Vibration Isolators
When correctly selected and installed, the SKA series can help:
- Reduce mechanical vibration transmission within its effective isolation frequency range.
- Provide resilient support for industrial equipment.
- Control oscillatory motion through damping.
- Offer a compact enclosed mounting configuration.
- Support vibration isolation in HVAC and industrial machinery installations.
- Accommodate customized equipment mounting requirements.
Actual performance must be verified using product characteristics and project operating conditions.
SKA Damped Spring Isolator vs. Conventional Spring Mounts
Conventional spring vibration mounts primarily rely on the elastic characteristics of steel coil springs to reduce vibration transmission.
Damped spring vibration isolators incorporate damping characteristics intended to control dynamic response, particularly near resonance and during transient operating conditions.
However, damping does not automatically increase isolation efficiency at every frequency. The appropriate damping level depends on the equipment’s operating characteristics and the vibration control objectives.
The SKA should therefore be evaluated using verified load-deflection, natural frequency, and damping data.
How to Select the Right SKA Spring Vibration Isolator
For accurate selection, customers should provide:
- Equipment type and model
- Total operating weight
- Number of required mounting points
- Load distribution at each mounting point
- Equipment operating speed (RPM)
- Dominant vibration excitation frequencies
- Required vibration isolation performance
- Desired spring deflection
- Available installation height
- Mounting hole dimensions
- Equipment center of gravity
- Expected horizontal forces and piping loads
- Operating temperature and environmental conditions
Our technical team can evaluate these parameters and assist with selecting a suitable spring vibration isolation solution.
Frequently Asked Questions
What is a damped spring vibration isolator?
A damped spring vibration isolator is a resilient equipment support component that combines spring compliance with damping characteristics.
The spring provides elastic support and can reduce vibration transmission, while damping helps control oscillation near resonance and during transient operation.
What is the difference between a damped spring isolator and a rubber vibration mount?
A spring isolator uses spring stiffness to establish its elastic support characteristics, while a rubber mount relies on elastomeric deformation.
Rubber generally provides inherent material damping, while spring-based systems may incorporate additional damping arrangements.
Selection depends on supported load, excitation frequency, required deflection, and installation conditions.
Can SKA spring isolators be used for water pumps?
The SKA series can be evaluated for compatible water pump installations.
Selection should consider pump operating weight, motor speed, mounting point loads, connected piping forces, and required vibration isolation performance.
Are SKA spring mounts suitable for HVAC equipment?
The SKA series can be considered for suitable fans, air handling units, chillers, and other HVAC mechanical equipment.
The selected isolator must provide the required load capacity, operating deflection, and installation characteristics.
How do I determine the required spring deflection?
Required spring deflection is related to the target natural frequency and supported load.
For an ideal linear spring under static gravitational loading, the natural frequency can be estimated from the static deflection:
fn ≈ 15.8 / √δ
Where fn is in Hz and δ is the static deflection in millimeters.
This simplified relationship is useful for preliminary selection, but actual product performance should be confirmed using manufacturer data.
Can SKA spring vibration isolators be customized?
Customization can be evaluated for load capacity, spring configuration, operating deflection, mounting dimensions, and installation requirements.
Customers should provide equipment information and technical drawings for review.
