Bonded Mounts
Heavy-duty rubber-to-metal bonded mounts designed to isolate severe engine vibration, absorb road shock, and provide fail-safe captive retention for powertrain and stationary machinery.
Types & Configurations of Bonded Mounts
Bell-Type Captive Engine Mounts
Pressed steel dome with captive central stud preventing equipment breakaway under high overturn moments.
Flanged Shear / Compression Mounts
Oval or diamond 2-bolt flanged brackets for diesel engines, generators, and compressors.
Hydro-Mount Hybrid Dampers
Rubber-metal bonded enclosure with internal fluid chamber for high amplitude low frequency damping.
Pedestal Machine Isolators
Cast iron or ductile iron base mounts with vulcanized elastomer cushion for heavy presses.
Heavy Off-Highway Cab Mounts
Multi-directional rubber-metal isolators providing acoustic isolation for driver cabins.
Key Industrial Applications
Specifications & Technical Details
Bonded Mounts can be precision-manufactured in custom dimensions, wall thicknesses, cross-sections, and durometers to match your exact application specifications. Below are typical engineering cross-section drawings and technical parameters for reference.

Material Selection & Properties
We offer specialized compound formulations tailored to chemical media, thermal extremes, static deflection, and dynamic fatigue requirements. The best material depends on your operating environment and required service life.
| Material / Polymer | Key Engineering Properties | Recommended Applications & Considerations |
|---|---|---|
| Natural Rubber + Carbon Steel | Maximum dynamic fatigue life & vibration decoupling | Suspension bushes, engine mounts, heavy cab isolators |
| Nitrile (NBR) + Mild Steel / Brass | Oil & grease immersion resistance with vulcanized bond | Rotary shaft seal inserts, fluid poppets, drive couplings |
| EPDM + Stainless Steel 304/316 | Exceptional weather, ozone, UV & polar solvent resistance | Solar mounting brackets, outdoor dampers, marine mounts |
| Viton® (FKM) + Stainless / Titanium | Resists aggressive fuels, hot oils, acids up to +220°C | Aerospace fuel valve seals, chemical pump impellers |
| Polyurethane (PU) + Steel Sleeves | Extreme load bearing & cut/tear abrasion resistance | Heavy forklift drive wheels, guide rollers, buffer plates |
