Thrust ball bearings are designed to withstand thrust loads during high-speed operation, and consist of washer-shaped rings with raceway grooves for ball rolling. Because the ferrule is cushion-shaped, thrust ball bearings are divided into two types: flat base cushion type and self-aligning spherical cushion type. In addition, this kind of bearing can bear axial load, but cannot bear radial load.
A thrust ball bearing is a type of rolling element bearing that is designed to support axial loads, or forces that act parallel to the shaft axis. Unlike radial ball bearings, which support radial loads, thrust ball bearings are designed to handle axial loads in a single direction.
Thrust ball bearings are typically composed of two washers and a ball bearing cage assembly. The washers are flat rings that are designed to support the axial load and provide a surface for the ball bearing cage assembly to rotate against. The ball bearing cage assembly is composed of a series of small, precision steel balls that are held in place by a cage or retainer.
The design of the thrust ball bearing allows it to handle high axial loads, making it ideal for applications where there is a lot of thrust force. These applications include machine tool spindles, automotive transmissions, and aerospace equipment.
One of the advantages of thrust ball bearings is their low friction, which makes them ideal for high-speed applications. They are also relatively easy to install and maintain, and can be designed to handle both thrust and radial loads if necessary.
The use of thrust ball bearings: only suitable for parts that bear axial load on one side and low speed, such as crane hooks, vertical water pumps, vertical centrifuges, jacks, low-speed reducers, etc. The shaft ring, seat ring and rolling elements of the bearing are separated and can be assembled and disassembled separately.
Thrust Ball Bearing Advantages:
1.High axial load capacity: Thrust ball bearings are designed to handle high axial loads in a single direction, making them ideal for applications where there is a lot of thrust force.
2.Low friction: Thrust ball bearings have a low friction coefficient, which makes them ideal for high-speed applications.
3.Easy to install and maintain: Thrust ball bearings are relatively easy to install and maintain compared to other types of bearings.
4.Cost-effective: Thrust ball bearings are generally less expensive than other types of bearings, making them a cost-effective choice for many applications.
5.Compact design: Thrust ball bearings have a compact design, which allows them to be used in applications where space is limited.
6.Customizable: Thrust ball bearings can be designed to handle both thrust and radial loads, making them a versatile choice for many applications.
Bearing steel is the steel used to make balls, rollers and bearing rings. Bearing steel has high and uniform hardness and wear resistance, as well as a high elastic limit. The uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict, and it is one of the most stringent steel types in all steel production. In 1976, the International Organization for Standardization ISO incorporated some common bearing steel grades into international standards, and divided bearing steel into 17 categories: fully hardened bearing steel, surface hardened bearing steel, stainless bearing steel, and high temperature bearing steel. steel number. Bearing steel is mainly used to manufacture rolling elements and rings of rolling bearings. Since the bearing should have the characteristics of long life, high precision, low calorific value, fast speed, good rigidity, low noise, and high wear resistance, the bearing steel is required to have: high hardness, uniform hardness, high elastic limit, and high contact fatigue. Atmospheric lubricant strength, necessary toughness, certain hardenability and corrosion resistance. In order to meet the above performance requirements, the uniformity of the chemical composition of the bearing steel, the content and type of non-metallic inclusions, the particle size and distribution of carbides, and decarburization are strictly required. Bearing steel generally develops in the direction of high quality, high performance and diversification. Bearing steel is divided into high carbon chromium bearing steel, carburized bearing steel, high temperature resistant bearing steel, stainless steel bearing steel and special bearing material according to characteristics and application environment.
Bearings are parts that support the shaft, used to guide the rotational movement of the shaft, and bear the load transmitted from the shaft to the frame. Bearings are widely used and demanding supporting parts and basic parts in the machinery industry. They are the supporting components of the rotating shafts or movable parts of various machines, and are also the supporting components that rely on the rolling of rolling bodies to realize the rotation of the main engine. Known as mechanical joints.
Compared with ordinary bearings, high temperature bearings have high temperature resistance up to 500°C or 800°C, greater bearing capacity, oxidation and corrosion resistance, high hardness and wear resistance, strong impact and bite resistance, smooth and shiny appearance, self-lubricating, low There is no lubricant for those with high speed, the load is 1.4 times that of ordinary bearings, and the average life is more than five times that of ordinary bearings. In addition to being different in performance and material, the expression of the model is also different.
The parts of the bearing are made of bearing steel and subjected to high-temperature tempering treatment, and the post code is in accordance with the regulations of JB/T2974 (the parts have been subjected to high-temperature tempering treatment, and the working temperature can reach 150C°, and the code is /SO; the sh07 parts have been subjected to high temperature After tempering treatment, the working temperature can reach 200°C, and its code is /S1; after high-temperature tempering, the working temperature can reach 250°C, and its code is /S2; after high-temperature tempering, the working temperature It can reach 300°C, and its set code is /S3; after high temperature tempering treatment, the working temperature can reach 350°c, and its set code is /S4).
