MTSV7000 Turbojet Engine Bearing

Monton can provide high-quality bearings for turbojet engines that withstand high temperatures, high speeds, and complex loads. The primary type of bearing used in turbojet engines is the angular contact ball bearing, which is mainly employed to withstand other moments. Its structural characteristics enable it to simultaneously handle radial and axial loads. In turbojet engines, such bearings are commonly used in positions that require supporting rotating components while bearing axial thrust. To enhance wear resistance and high-temperature performance, angular contact ball bearings are often made from ceramic materials, such as ceramic ball bearings. For small gas turbine engines (like micro turbojet engines), due to their extremely high operating speeds (up to 60,000–150,000 rpm), the performance requirements for bearings are even more stringent.

Turbojet bearings are critical components in turbojet engines that support rotating parts (such as compressors and turbine rotors). Their performance directly determines the engine's reliability, efficiency, and lifespan. During the development of many turbojet engines, standard-sized bearings have been consistently used. Since bearings play a crucial role, their accuracy and durability are key to ensuring the continued operation of turbojet engines at the lowest cost.

Therefore, we have invested significant time in developing high-precision ceramic hybrid bearings. We have proposed a full ceramic bearing solution suitable for most models of gas turbines and can now provide a complete set of ceramic bearing solutions (with or without cages). The bearings we supply for the turbojet engine market meet ABEC 7 precision (also known as P4 grade) and offer competitive advantages in both quality and price! Si3N4 (silicon nitride) ceramic balls are used because they are best suited for high-speed, long-durability applications. Through optimization and improvements, the weight of the bearings is reduced, and the inertia of the ceramic balls is minimized. Bearings with these ceramic balls significantly extend component lifespan, and this ceramic-on-ceramic system also offers notable resistance to hard particles rolling into the raceways. Turbojet engines utilize a variety of bearing types, including angular contact ball bearings, full-floating bearings, thrust bearings, as well as air bearings and anti-friction bearings. These bearings have high requirements in material selection, design, and manufacturing to ensure stable operation and optimal performance of turbojet engines under complex working conditions.
