What are Low-Temperature Bearings? 2026-09-22 Low-temperature bearings are a type of bearing engineered with specialized materials and structural designs to maintain stable operation under low-temperature conditions. In addition to differences in materials and construction compared to conventional bearings, they also reduce friction-induced heat generation by lowering the friction coefficient, enabling them to maintain low temperatures during prolonged operation. Below is a detailed introduction to low-temperature bearings. I. What Are Low-Temperature Bearings? 1. Materials for Low-Temperature Bearings Low-temperature bearings are typically manufactured using stainless bearing steels such as 9Cr18 and 9Cr18Mo. The bearing rings are made of G95Cr18 and G102CrMo stainless steels, or imported high-nitrogen stainless steels such as Cronidur®30 (X30 CrMoN15-2) and X.D15N.W (X40 CrMoVN16-2). The rolling elements are produced from G95Cr18 and G102CrMo stainless steels, or ceramic materials such as silicon nitride (Si₃N₄) and zirconia (ZrO₂). The cages are made of non-metallic or ceramic materials that offer self-lubricating, wear-resistant, and low-temperature-resistant properties, used in hybrid ceramic ball bearings. These materials are capable of functioning properly at operating temperatures as low as –253°C. For applications below –253°C, 6Cr14Mo material may be used, but it must be operated in a vacuum environment. 2. Types of Low-Temperature Bearings The cryogenic bearings produced by MONTON are primarily available in deep groove ball bearing and angular contact ball bearing configurations. Detailed model specifications are provided below.

Application Fields of Low-Temperature Bearings Low-temperature bearings are suitable for a wide range of equipment used to handle liquefied gases, such as natural gas pumps, liquid nitrogen pumps, liquid hydrogen pumps, liquid oxygen pumps, liquid pumps for rockets and missiles, and spacecraft. These devices operate at persistently low temperatures, where conventional bearings may fail. Low-temperature bearings are therefore essential to ensure reliable operation under such conditions. II. Maintenance Methods for Low-Temperature Bearings 1. Daily Cleaning: The cleanliness of low-temperature bearings directly affects their lubrication performance. Contamination can hinder the formation of a lubricating oil film, accelerate lubricant degradation and aging, and impair lubrication effectiveness, ultimately shortening bearing service life. 2. Lubrication: During operation, attention must be paid to prevent overheating caused by inadequate lubrication. Therefore, selecting the appropriate lubricant is crucial. Insufficient lubricant supply may compromise lubrication performance and lead to seizure. 3. Regular Inspection: The cleanliness of the lubricating oil should be regularly monitored to determine whether replacement is necessary, thereby avoiding lubrication issues or other failures caused by contamination. If solid particles in the lubricating oil are smaller than 10 μm, the service life of the low-temperature bearing can be extended several times over.
Introduction to the application of hybrid ceramic ball bearings in turbojet engines 2025-08-18 The application of hybrid ceramic ball bearings manufactured by MONTON Bearing in turbojet engines is mainly reflected in the following aspects: 1. High temperature and high-speed adaptability The hybrid ceramic bearing adopts silicon nitride ceramic balls, which can maintain hardness at high temperatures of 400 ℃ and fail at 800 ℃, significantly better than the performance degradation problem of metal bearings at high temperatures. Its thermal expansion coefficient is small, which can effectively reduce bearing expansion deformation caused by temperature changes and adapt to the high-temperature working environment of micro turbojet engines. 2. High speed and stability The oil-free self-lubricating properties of ceramic balls enable hybrid ceramic bearings to achieve speeds up to 1.5 times that of metal bearings, solving the design requirement for turbine rotors to reach 120000 revolutions per minute. The experiment shows that it can maintain stability even after continuous operation for 5 hours, avoiding problems such as smoking and shaft holding of metal bearings at 40000 revolutions per minute. 3. Failure mechanism and improvement Research has shown that the failure mode of hybrid ceramic bearings in micro turbojet engines is mainly surface metal detachment, and material optimization and structural design improvements are needed to extend their service life. Finite element analysis combined with experimental verification can effectively predict the critical speed range, providing a basis for bearing selection. 4. Breakthrough in localization MONTON Bearing independently developed hybrid ceramic bearings, breaking the foreign monopoly on high-speed aviation bearings and becoming the fifth country in the world to mass produce aerospace ceramic bearings. The hybrid ceramic bearings manufactured by MONTON Bearing have significantly improved the combustion efficiency, thrust output, and reliability of micro turbojet engines by integrating the advantages of metal and ceramic materials, becoming one of the key technologies in the aerospace field.
