Item No. AVM-021
Rubber-metal bushings — also known as bonded rubber-to-metal isolators — are engineered to reduce structure-borne noise and vibration transmission in machinery. By absorbing, dissipating, and isolating mechanical energy, these mounts protect industrial, HVAC, and medical equipment, enhance operational stability, and extend service life.
The rubber-to-metal bond is the core of the design: a resilient rubber element is permanently vulcanized to a metal inner and/or outer sleeve, combining the damping properties of rubber with the structural strength and mounting precision of metal. This makes them suitable for high-load, high-cycle applications where pure rubber or plastic components would fail.
Permanent rubber-to-metal bond – vulcanized for maximum strength and durability
Premium rubber compounds – natural rubber, NBR, EPDM, silicone, neoprene, and custom blends
Bonded metal sleeves – steel, stainless steel, or aluminum inner/outer sleeves
Excellent vibration isolation – absorbs and dissipates mechanical energy effectively
Structure-borne noise reduction – lowers transmission through frames and panels
High load capacity – supports light to heavy equipment and machinery
Superior fatigue resistance – withstands continuous cyclic loading
Tight dimensional tolerances – precision molded and machined for exact fitment
Weather & chemical resistance – grade-dependent resistance to oil, heat, ozone, and moisture
Fully customizable – size, shape, hardness, rubber compound, sleeve type, and bonding method
Permanent Rubber-to-Metal Bond – Vulcanized bonding ensures the rubber element cannot separate from the metal sleeve, delivering reliable performance under extreme loads, vibration, and temperature cycling.
Effective Vibration Isolation – Absorbs, dissipates, and isolates mechanical energy across a wide frequency range, protecting equipment and surrounding structures from harmful vibration.
Structure-Borne Noise Reduction – Significantly lowers noise transmission through frames, panels, and floors, creating quieter and more comfortable working environments.
High Load & Fatigue Capacity – The metal sleeve provides structural strength while the rubber element absorbs dynamic loads, enabling reliable performance in heavy-duty and high-cycle applications.
Precision Fit & Dimensional Stability – Tight molding and machining tolerances ensure exact fitment and consistent performance, even under continuous mechanical stress.
Industrial machinery – motor mounts, pump isolators, compressor bushings, machine tools
HVAC systems – air handling units, chillers, fans, cooling towers, ductwork
Medical equipment – diagnostic machines, imaging equipment, laboratory instruments
Power generation – generators, turbines, auxiliary equipment mounts
Railway & mass transit – suspension bushings, engine mounts, auxiliary isolation

Standard: Goods are typically supplied in about 20-25kg/carton.
Standardized Pallets: Goods are stacked on heat-treated (ISPM 15) or plastic pallets, optimized for forklift handling. Rigid Corner Protectors: High-impact cardboard corner guards are applied to the full height of the stack. This prevents the straps from cutting into the rubber and maintains the vertical integrity of the pallet.
What is a rubber-metal bushing?
A rubber-metal bushing is an anti-vibration component in which a rubber element is permanently vulcanized to a metal inner and/or outer sleeve. It combines rubber's damping properties with metal's structural strength.
What materials are available for rubber-metal bushings?
We offer natural rubber, NBR, EPDM, silicone, neoprene, and custom compounds, with steel, stainless steel, or aluminum sleeves.
What is the typical hardness range?
Our bushings range from 40 Shore A (soft, high-isolation) to 85 Shore A (firm, high-load). We can adjust hardness to meet your application needs.
Can these bushings withstand high temperatures?
Yes. Standard compounds perform from -40°C to +120°C. High-temperature silicone and FKM grades are available for extreme heat applications.
Are these bushings oil and chemical resistant?
NBR and specialty compounds offer excellent oil, grease, and fuel resistance. EPDM is ideal for water, weather, and outdoor exposure. Please consult our team for specific chemical compatibility.
How do I choose the right bushing for my equipment?
Selection depends on equipment weight, vibration frequency, mounting configuration, and environmental conditions. Contact our team for technical recommendations.
What quality standards do you meet?
All products are manufactured under ISO 9001 quality management systems. Material certifications and test reports are available upon request.
Do you offer custom sizes and shapes?
Absolutely. We produce bushings to your technical drawings or samples – any size, shape, hardness, material, and sleeve configuration. OEM orders welcome.
