Professional Rubber Bonded Metal Bushings Manufacturer
As a specialized manufacturer of rubber-to-metal bushings, we understand that every industrial application requires precise performance when it comes to damping, vibration isolation, and shock absorption. Whether standard components or non-standard custom designs, rubber metal bushes, rubber metal bushings, and rubber bonded bushings form the core of our technical expertise. Leveraging years of engineering experience and continuous innovation, we deliver high-reliability rubber-metal composite products to clients worldwide.
What is a Rubber Metal Bushing?
A rubber metal bush (also known as a rubber metal bushing or metal rubber bushing) is a composite functional component manufactured by bonding an elastomeric rubber layer directly to metal components through vulcanization. Typically consisting of an inner metal tube, an outer metal tube, and an intermediate rubber layer, the chemical bond created between the rubber and metal sleeve provides exceptional shock absorption and vibration attenuation under radial, axial, torsional, and cardan loads.
In the industry, these products are known by various names, including anti-vibration bushes, rubber isolator bushings, bonded rubber bushes, and rubber-metal bushes. Regardless of the terminology, their primary function remains consistent: acting as flexible connection elements that isolate vibration transfer between two rigid components, absorb impact energy, and allow controlled relative movement.
Why Choose Us: Custom Manufacturing Advantages
- Full-Spectrum Material Formulation: Select from NR, NBR, CR, EPDM, Silicone, HNBR, and FKM compounds optimized for oil, ozone, thermal, and fatigue resistance.
- Advanced Metal Insert & Sleeve Machining: We manufacture a standard rubber bushing with metal insert or complex rubber bushing with metal sleeve structures (multi-step bores, threads, splines, flanges, and thin-walled sleeves up to 500mm). Material options include carbon/alloy steel, stainless steel, aluminum, and brass with phosphating, zinc plating, or Dacromet surface treatments.
- High-Strength Bonding & Advanced Vulcanization: Advanced surface pretreatment (shot blasting, phosphating) and adhesive systems prevent interface debonding under extreme dynamic shear loads.
- Strict Quality Assurance: Certified to ISO 9001 and IATF 16949 with full compliance with RoHS and REACH environmental standards.
