MONTON can supply full ceramic turbojet bearings for the model gas jet turbine fraternity.

As the bearing plays a vital role, its accuracy and durability are key in making sure that your hobby continues with minimal costs.For this reason we have spent considerable time in trying to move one step beyond high precision steel/ceramic hybrid bearings.

Turbojet bearings are main components that support rotating components such as compressors and turbine rotors in turbojet engines, and their performance directly determines the reliability, efficiency, and lifespan of the engine.During the development of many turbojet engines, standard size bearings were used. Since bearings play a vital role, their accuracy and durability are key to ensuring that turbojet engines continue at the lowest cost.

Hence, we spent a lot of time developing high-precision ceramic hybrid bearings. Proposed an all-ceramic bearing solution suitable for most types of gas turbines. We can now provide a full set of (without cage/with cage) ceramic bearing solutions. The bearings our company provides for the turbojet engine market are ABEC 7 precision ( Also known as P4 level) and has competitive advantages in quality and price! Use Si3N4 (silicon nitride) ceramic balls as it is best suited for high speed, long durability applications. Bearings with these ceramic balls significantly increase component life through optimized improvements that reduce bearing weight and reduce the inertia of the ceramic balls.

This ceramic-on-ceramic system also significantly resists the rolling of hard particles into the raceways. Turbojet engines There are various types of bearings used in turbojet engines, including angular contact ball bearings, fully floating bearings, thrust bearings, air bearings and anti-friction bearings. These bearings have high requirements in terms of material selection, design and manufacturing to ensure that the turbojet engine can operate stably and achieve optimal performance under complex working conditions.

Full ceramic bearing solutions for most model gas turbines we can now offer a full complement (no cage/retainer) ceramic solution with an ABEC 7 tolerance (also denoted as P4) and pricing which is competitive with their steel counterparts! The Si3N4 (Silicon Nitride)ceramic grade is used as this is most suitable for high speed, long endurance applications.

With reduced weight, reduced ball inertia and massive improvements in low lubrication scenarios  these full ceramic possibilities offer significant improvements on component life, especially when you consider what happens to  various engine components when steel/hybrid bearing lubrication systems fail. Due to the nature of ceramic balls rolling on a ceramic inner and outer rings, the high hardness values dictate higher life and far more stable running characteristics. This ceramic on ceramic system also provides significant resistance against hard particles being rolled into the raceways  (unlike their steel counterparts). Corrosion resistance is 100% of course  with no ferritic content at all.
