Mechanical Products
CEF Industries brings decades of aerospace engineering expertise to a full range of mechanical products. From precision ball screws and flexible shafts to custom gear boxes, oil-less air compressors, and high-performance pumps, our mechanical product line is designed and manufactured to meet the most demanding requirements in defense and commercial aerospace.
CEF designs, manufactures, and tests AS9100D-certified ball screws for aerospace and defense applications. With 30+ years of experience, we deliver multiple configurations, high-load capability, gun drilling up to 60 inches, and custom solutions — backed by formal analytical design verification including FEA, FMEA, and in-house acceptance testing.
CEF’s oil-less air compressors are a proven industry standard for aerospace and defense potable water, pneumatic, and pressurization systems. Dynamically balanced, corrosion-resistant, and qualified to RTCA DO-160D, our piston and scroll compressor designs are fielded across commercial, military, regional, business jet, and helicopter platforms worldwide.
CEF flexible shafts provide efficient rotary power transmission through, around, and over structural members, bulkheads, and other aircraft obstructions. With up to 90–95% transmission efficiency, nearly unlimited connection ratios, and up to 180° of offset capability, they are a lightweight and cost-effective alternative to torque tubes, U-joints, and gear trains.
CEF is a recognized leader in custom aerospace gear box design, manufacturing, and testing for fixed-wing, rotorcraft, and defense platforms. From bevel and helical to planetary and worm gear configurations, our gear boxes are engineered to AGMA Class 12 precision and built to meet your specific load, packaging, and qualification requirements.
CEF designs and produces high-performance motor-driven centrifugal and gerotor pumps for aerospace cooling, fuel, lubrication, hydraulic, and potable water applications. Our wet-motor centrifugal pump designs eliminate shaft seals and use hydrodynamic bearings for long service life across a wide range of operating fluids and environments.
