TIANHE 2 23944-2CS sealed roller bearing are fitted with a large number of long symmetrical large-diameter rollers, capable of withstanding very heavy loads. Special structures of raceway surface as well as the best quality ensure spherical roller bearings the lowest friction including C and CA-bearing.
Compared with conventional spherical roller bearings, tianhe bearings run cooler. They are able to withstand heavier axial loads, or up to a higher speed.

- Q: What's the connection between the crankshaft and the sliding bearings?
- The crankshaft is the shaft, the Bush is tile, the upper and lower two pieces of tile and together is the sliding bearing, can serve as the support of the crankshaft.
- Q: Vacuum environment, the temperature is expected to 200 degrees, would like to use sliding bearings, mainly to consider the space is small. Only the temperature is high and the expansion will cause problems. Who used it and how to solve inflation?
- The vacuum environment, is expected to 200 degrees temperature, want to use the sliding bearing, mainly on account of the small space, the environment is not suitable for sliding bearing, sliding bearing can be at a temperature of about 200 degrees, but the high temperature expansion, easy to get stuck.
- Q: What are the most afraid of sliding bearings?
- Main faultSliding bearing at work due to shaft and bearing contact friction, causing the surface heat, wear even "killed", so in the design of bearings, should choose good antifriction bearing sliding bearing materials, suitable lubricant and the supply of the appropriate method to improve the bearing structure for thick film lubrication etc..1, tile surface corrosion: spectral analysis found that non-ferrous metal concentration is abnormal; there are many non-ferrous metals in the spectrum of sub micron wear particles; lubricating oil moisture exceeded acid value exceeded.2, the surface of the journal corrosion: spectral analysis found that iron concentration is abnormal, there are many iron components in the iron spectrum of submicron particles, lubricating oil moisture exceeded or acid value exceeded.3, the axle neck surface strain: iron spectrum in the iron cutting abrasive particles or black oxide particles, the metal surface has the tempering color.4. The fretting wear of the back of the tile: the spectral analysis shows that the iron concentration is abnormal. There are many ferrous components, submicron wear particles in the iron spectrum, and the water and acid value of lubricating oil is abnormal.5, bearing surface strain: iron spectrum found in the cutting abrasive particles, abrasive particles for non-ferrous metal.6, tile surface spalling: iron spectrum found in many large size fatigue spalling alloy, wear particles, layered abrasive particles.7, bearing burning tile: iron spectrum, there are more large size alloy abrasive particles and ferrous metal oxides.8, bearing wear: as a result of the metal characteristics of the shaft (hardness, poor yield) and other reasons, easy to create adhesive wear, abrasive wear, fatigue wear, fretting wear and other conditions.
- Q: What is Bush? What do you mean by scraping the Bush? How to operate?
- The difference between sliding and rolling bearings is that the former journal and bearing surface work to form sliding friction, while the latter mainly form rolling friction.
- Q: In general, what kind of sliding bearing material is used in the case of large load?
- The material selection of sliding bearing is related to load, speed, lubrication conditions, and the self-lubricating materials chosen in different working conditions are different.
- Q: sliding bearing
- There is a fundamental difference between plain bearings and rolling bearings.The rolling bearings bear the weight by the ball bearings, and the contact between the friction pairs is unavoidable, and the wear is unavoidable. Just imagine how many tens of tons of rotating shaft, 3000 rpm per minute, if rolling bearings can hold for how long?The static and dynamic parts of the sliding bearing are not in direct contact. When rotating at high speed, the rotating shaft is raised by a high pressure oil film to form a suspension state. So, as long as properly used, sliding bearings can carry dozens of tons of rotating shaft, continuous operation thousands of tens of thousands of hours.
- Q: Are the motors sliding bearings at both ends?
- In general, both ends of the motor are using deep groove ball bearings, large motors such as 1000KW or more will generally use sliding bearings, also known as bearing.
- Q: Can the sliding bearings move in axial direction?
- Sliding bearings can not achieve axial and circumferential movement?
- Q: What are the technical requirements and precautions for the assembly of plain bearings?
- When the machine does not work, the axle is resting on the bearing and exerts pressure on the bearing.
- Q: What are plain bearings, roller bearings, roller bearings, needle roller bearings?
- Needle bearing roller bearings are cylindrical roller, relative to its diameter, the roller is thin and long. This roller is called needle roller. In spite of the small cross section, the bearing still has a high load capacity, so it is especially suitable for radial space limited occasions.
