Our Specialty Products
Elastomeric Bearings
Our Elastomeric Bearing solutions are engineered with Aerospace grade performance. Designed to operate under extreme loads, temperatures, and vibration profiles. Our elastomeric bearing solutions are engineered to deliver predictable stiffness, stable dynamic behavior, and long-term durability, helping aircraft manufacturers improve performance, reliability, and passenger comfort without compromising safety, weight, or space.
From rotorcraft to fixed-wing aircraft, engines and defense platforms, our bearings are trusted wherever vibration control is critical to mission success.
Vibration Isolators and Mounts
Our elastomeric isolators and mounts are engineered to reduce vibration, noise, and structural loads—enhancing passenger comfort, protecting aircraft systems, and ensuring reliable propulsion performance across the flight envelope. The mounts are engineered to resist aging, creep, and environmental exposure over extended service internals. The durable designs help minimize unscheduled maintenance improving our customers lifecycle costs.
Our isolators range from aircraft cabin vibration controls to engine or transmission mounts which manage high static and dynamic loads while controlling vibration transmission to airframe structures.
Dampers
Our dampers performances are proven within Aerospace systems. Aerospace platforms are exposed to continuous vibration, transient shock events, and extreme environmental conditions. Our elastomeric dampers are engineered to deliver controlled energy dissipation, high damping efficiency and predictable dynamic performance, helping improve system reliability, passenger comfort, and structural integrity.
Utilizing our proprietary elastomer material with application‑specific design, our damping solutions support aerospace OEMs in meeting stringent performance, durability, and certification requirements. Our dampers are used everywhere from rotorcraft rotor systems to motion control systems impacting shock loading events focused on durability, environmental resistance, and stable dynamic behaviors.
Molded Rubber Products
Aerospace applications demand materials and components that perform reliably under extreme conditions. Our customer‑specific molded rubber products are engineered to support sealing, vibration control, load management, and environmental protection across a wide range of aerospace platforms.
By combining advanced elastomer materials with application‑driven design and controlled manufacturing processes, we help aerospace OEMs and Tier suppliers achieve consistent performance, durability, and compliance throughout the product lifecycle.
Our rubber molded products are based on compression molding which range from customer seals, boot assemblies used in Rotorcraft systems to gasket assemblies.
