Sepcification:
Angular contact ball bearings can bear radial load and axial load at the same time and also can bear pure axial load. Their ability of axial load is determined by contact angle and is increased with contact angle increasing; speed limit is higher; stiffness is big and can be pre-adjusted. They are applicable to high-speed and high-precision site.
Product application:

- aircraft engine spindle
- high frequency motor
- printing machinery
- air compressor
- gas turbine

- Q:The study on the friction and wear behavior of thrust bearings under oil lubrication conditions at home and abroad, their significance and future prospects!!!! The best reference source. Thank you if there are similar can be sent to my mailbox.
- A journal bearing bearing axial thrust and restricting axial movement of the shaft. In two [1] thrust bearing friction surface is completely separated from the fluid film is divided into hydrodynamic thrust bearing and hydrostatic thrust bearing, suitable for high speed operation. Two a thrust bearing whose surface is not completely separated by a fluid film operates under boundary lubrication (see lubrication) and is only suitable for low speed operation.
- Q:Advantages and disadvantages of plain bearings relative to rolling bearings
- Advantages of plain bearings:1, and rolling bearings of the same volume of load capacity is much greater.2, vibration and noise is small, used in high precision requirements, but also does not allow vibration occasions.3, the metal foreign body caused little impact, it is not easy to produce early damage.Well, summed up the shortcomings of many advantages less, but in different use occasions, sliding bearing performance is very prominent! QQ 1054839354 is willing to share the bearing knowledge for you!
- Q:What material is suitable for sliding bearings?
- 2. copper powder layer 0.20~0.35mm, with good bearing capacity and wear resistance, good thermal conductivity, can timely transfer the heat generated during the operation of bearings. The composite can be infiltrated into the gap of copper powder balls, and the bonding strength is improved.
- Q:What are the main applications of plain bearings?
- In order to improve the friction properties of the bearing surface, the antifriction material layer, which is cast on its inner surface, is called the bearing lining. Bearing and bearing lining materials are collectively referred to as journal bearing materials. The application of sliding bearings is usually under the condition of high speed and light load.For example: construction machinery, marine equipment, water conservancy projects, aviation, aerospace, railways and other fields.Compared with rolling bearings, plain bearings have the characteristics of high bearing capacity, good seismic resistance, stable and reliable operation, low noise and long service life.
- Q:Tilting pad radial sliding bearing which features
- The lubricating oil from the gap between each pad into the bearing, from both ends of seal bearing ring hole discharge. If you ignore the effect of pad inertia, friction force and the oil film shearing force of internal friction fulcrum, each pad to the axial diameter of the oil film force is always through the center shaft, the rotor movement in bearings only, will not have a leading axis
- Q:What effect does the sliding bearing have on the top gap?
- There must be a gap between the clearances.The fit between the sliding bearing and the shaft is clearance fit. The top gap is normally pressed by lead. The top clearance is 1/1000 or 1/1000 of the axle neck, and five of the gap is 1/2 of the top clearance.
- Q:What is the axial series momentum of plain bearings?
- Rolling bearings are widely used in various machines and institutions because of their small friction resistance, quick start-up, high efficiency, high rotating accuracy, simple lubrication and easy assembly and disassembly. Rolling bearings are standard parts, which are produced by the bearing factory in large quantities, and the designers can choose them directly according to their needs. 14.2.2 rolling bearing type and characteristics, according to the shape of the rolling body, rolling bearings are divided into ball bearings and roller bearings. According to the main direction of load bearing can bear, can be divided into radial bearings (mainly bear radial load, thrust bearing) (axial load), thrust bearing (can bear radial load and axial load).
- Q:What are the structures of journal bearings, rolling bearings or plain bearings?
- As far as I know, there seems to be no uniform standard in our country at the moment. So I'm sorry, but I still can't provide you with the organization chart. Supplement:Disclaimer: my previous answer was mixed and invalid!!! Totally agree with the frozen answer!!!Today's journal bearings are mostly used in the field of automobile technology.
- Q:High speed heavy duty important sliding bearing, bearing material with tin base bearing alloy or casting tin bronze?
- I am an expert here. I have opened a sliding bearing factory. Hubei Yuhang bearing bush Co., ltd.. Lining material: 1 bearing alloy, tin bearing alloy, Babbitt is common, grade 11-6 and 8-6, suitable for high speed and light load, load and heavy load (load, special design, Babbitt bearing) than copper alloy with excellent performance, after all the price is higher than copper alloy is less common equipment: blower, turbine, steam turbine, thermal power, motor, oxygen generator, compressor bearing.
- Q:Why are lubricated bearings lubricated by sliding bearings? Why grease lubrication?
- Sliding bearings directly contact the contact surface, high speed, oil lubrication can improve the good lubrication. If grease lubrication, slightly bad lubrication, immediate high temperature damage, the consequences are not envisaged.
