Follow on Google News | Saint-Gobain Seals’ Specialized Bonded Rulon® Bearings Excel in Aerospace & Defense ApplicationsSaint-Gobain Seals continues to successfully provide specialized and beneficial bonded Rulon® filled PTFE bearings to manufacturers in the aerospace and defense industries.
By: Saint-Gobain Seals The process of bonding Rulon® or any filled PTFE material to a metal surface can be a difficult task as PTFE does not naturally lend itself to bonding because it has one of the lowest surface energies and is hydrophobic. Saint- The first step to bonding the Rulon® product is to chemically etch the material. Next, the proper adhesive must be chosen for compatibility with both the Rulon® material and the metallic substrate as it must be applied properly and be able to maintain the bond in the intended environment and application. The processes of etching filled PTFE and then bonding it to a metal surface can be very delicate, sensitive to time and environment, and dependent on precise manufacturing techniques. Without the proper experience, the materials can be damaged during the manufacturing process or quickly degrade while in use. A popular application of Rulon® bonded bearings is in thrust reverser systems on jet aircraft. A thrust reverser system helps slow down an aircraft just after touchdown, resulting in shorter landing distances, reduced wear on brakes and improved safety. One common system consists of doors built into the engine nacelle. When closed, the doors are integrated into the shape of the exhaust section of the engine, allowing for forward thrust. When deployed, the doors open to block the rearward flow of the exhaust, redirecting the exhaust forward and thus causing deceleration of the aircraft. Rulon® Rulon® bonded bearings have also been used in missile launch systems. Many systems hold a missile inside a canister, which also functions as a launch tube. When the missile is fired, it escapes the canister while sliding against the canister's internal structure at a high speed and in an extremely hot and dry environment. To ensure proper missile operation and extend the lifetime of the reusable launch system, a high-performance linear bearing surface for the missile to slide against is essential. The Rulon® product is an ideal material due to its low coefficient of friction, resistance to wear, and its ability to withstand brief periods of extreme heat. Saint-Gobain Seals is the only source of genuine Rulon® polymer material. Each standard Rulon® material and hundreds of other custom Rulon® blends have been developed to meet a set of specific application requirements while also remaining versatile. Some popular materials for bonded bearings in aerospace and defense include their Rulon® AR and Rulon® W2 grades. This product line not only assists aerospace manufacturers but also has been used in other industries such as transportation: To learn more about Saint-Gobain Seals’ Rulon® product line, other product lines and its strategic business unit, visit www.seals.saint- About Saint-Gobain Seals (http://www.seals.saint- Saint-Gobain Seals is a strategic business unit under Saint-Gobain Performance Plastics’ Engineered Components SOA (sector of activity); our parent company, Saint-Gobain, is one of the world’s top 100 industrial groups.
