Product Overview
Reliable custom rubber parts for industrial applications
Quick Answer
This rubber isolator set features five fan-shaped damping blades with perforated edges and a matching interlocking base with snap-fit connectors. The blade-and-base assembly allows adjustable stiffness by adding or removing blades — making it a tunable vibration isolation solution for HVAC compressors, industrial automation equipment, electronic enclosures, and precision instruments. Available in NR and EPDM compounds with custom Shore A hardness for OEM applications.
Overview
The multi-blade rubber vibration isolator is an innovative anti-vibration mounting system consisting of stackable elastomeric blades and an interlocking rubber base. Unlike conventional pad or stud-type isolators, the fan-blade architecture distributes compressive and shear loads across a larger effective surface area, delivering superior vibration attenuation across a broad frequency range.
The perforated edge design on each blade reduces effective rubber stiffness without increasing the physical footprint — a key advantage for space-constrained installations. The snap-fit base with four locking connectors ensures the blade stack remains positionally stable under dynamic load conditions.

Application Scenarios
Designed for versatile deployment across industries where vibration control, noise reduction, and equipment protection are critical:
Industrial Automation
Ideal for vibratory bowl feeders (parts feeding systems) and conveyor drive unit mounting, where consistent low-frequency isolation is essential to maintain component sorting accuracy and belt tracking stability.
HVAC & Building Services
Widely used under compressor units, fan coil bases, and cooling tower support feet to prevent structure-borne noise transmission into building frames — a critical requirement under increasingly stringent building acoustic standards in Europe and North America.
Electronics & Server Infrastructure
Suitable for server rack base isolation, precision instrument frames, and electronic enclosure mounting, protecting sensitive components from ambient floor vibration in data centers and laboratory environments.
Engines & Generators
Effective as base isolators for small diesel generator sets, portable power units, and engine test benches, reducing vibration transmission to surrounding structures and extending service life of mounting hardware.
Medical & Laboratory Equipment
Used under high-magnification microscopes, analytical balances, and laboratory instruments where sub-micron vibration isolation is required for measurement accuracy and repeatability.
Construction & Agricultural Machinery
Applied to small vibratory compactors, drilling rigs, and agricultural equipment cabs to attenuate operator-transmitted vibration and protect onboard electronics from shock loading.
Transportation & Vehicle Electronics
Used in vehicle instrument panel mounting, in-cab electronic control unit (ECU) brackets, and onboard equipment fixtures where road-induced vibration must be decoupled from sensitive electronics.
Why Choose Multi-Blade Design?
- Tunable stiffness: Add or remove blades to match the isolator’s natural frequency to your equipment’s excitation frequency — no need to reorder different durometer grades
- Broad frequency isolation: Fan-blade geometry provides effective isolation from 10Hz to 200Hz
- Perforated edges: Reduce dynamic stiffness independently of base compound hardness
- Snap-fit base: Maintains positional alignment under multi-directional vibration loads
- Compact footprint: Higher isolation performance per unit area versus conventional flat rubber pads
Frequently Asked Questions
Q: How do I select the correct number of blades for my application?
A: Blade count determines total stiffness. For lighter loads or lower excitation frequencies, fewer blades are recommended. Our technical team can assist with natural frequency calculation based on your equipment weight and operating RPM.
Q: Can the rubber compound be customized for oil or chemical exposure?
A: Yes. Standard supply is NR or EPDM. For oil-splash environments, NBR (nitrile rubber) is available. For high-temperature or chemical-resistant applications, EPDM or CR (chloroprene) compounds are recommended.
Q: Are these isolators suitable for outdoor installation?
A: EPDM compound isolators are UV- and ozone-resistant and suitable for outdoor HVAC and rooftop equipment. Standard NR compound is recommended for indoor use only.
Q: What is the load capacity per isolator set?
A: Load capacity depends on blade count, compound hardness, and contact area. Please submit your application weight and footprint dimensions for a formal load rating confirmation.
