Engine Mount Bearings

Any aircraft contains a wide variety of bearings—in engines, in landing gears, in rotors, all crucial places and tight spaces. The engine mount is a foundation that connects the engine with the main body or frame of the aircraft. It serves various purposes, like connecting the engine with the fuselage, suppressing the vibrations of the engine, and distributing them safely to the whole aircraft structure for a smooth flight.

Generally, there are two types of roller bearings used in the aircraft engine: the straight roller and the tapered roller bearings. Straight roller bearings are used where the bearing is subjected to radial loads only. Engine mount bearings allow for a certain degree of gimbal, and when that articulation is compromised replacement is the only solution. It’s crucial that bearings are high corrosion resistance, oxidation resistance, strength at high temperatures, and creep resistance. Bearings come in all shapes and sizes but are all incredibly durable therefore their repair tools need to be just as, if not more, resilient than the bearings.

Engine mount bearing repair jobs are unique due to the immediate need they create and the different specifications of the bearings. Smith Machine and Tool manufactures both individual tools and toolkits for these bearings necessary for AOG and MRO. For these tools, we take careful consideration of design, material, and process in manufacturing to meet the complex challenges of these repairs -- all within industry best lead times. Our engine mount bearing tools are manufactured from M42 tool steel with a Crosal-Plus high-heat coating (more than 3200 HV Vickers) to increases our tools’ efficacy and longevity. Our tools can ease the repair of a seized engine mount bearing with little to no troubleshooting and increased reliability. Whether you’re looking for standard sizing or need customization, our facility is fully capable of adapting to customer needs.
