The Fc type and FCD bearing can allow the shaft to generate a displacement in both directions between the shaft relative to the bearing housing. Inner ring or outer ringless cylindrical roller bearings, the inner ring and outer ring can be relatively moved axially, so it can be used as a free end bearing. Among […]

The application of conical cross roller in the vertical lathe is very helpful to study the application of cross rollers in CNC vertical lathes. When the bearing is large, the contact force area between the raceway and the roller is significantly reduced, and the load distribution is not uniform, and the bearing swap is not […]

All changes to the record should have the signature or initials of the person who made the change to clarify their responsibility. Therefore, when making measurements and using measurement results, the measurement uncertainty must be considered. Authenticity is the original record that faithfully reflects the actual situation of local verification and calibration at that time, […]

The post code indicates the supplementary code added after the basic code of the bearing when the FAG bearing structure shape, size, seal, cage, tolerance, clearance, heat treatment, packaging, technical requirements, etc.——Thrust cylindrical roller FAG bearing race. S2-FAG bearing ring has been subjected to high temperature tempering treatment, and the working temperature can reach 250℃. […]

The dimensions that make up the dimension chain are called rings. The calculation process of the dimensional chain is usually referred to as the solution of the dimensional chain.In equipment maintenance, the use of dimensional chain principles to analyze problems is conducive to solving the problems of positional dimensional accuracy and positional relationship accuracy between […]

The parts adopt the method of reserved processing amount. Use reasonable cooling methods: The influence of the cooling process of the metal on the deformation after quenching is also a very important cause of deformation. The content includes monitoring the operating mechanical bearing status, replenishing or replacing lubricants, and regular disassembly inspections. Check the state of […]

The impact on metal foreign bodies is small, and it is not easy to cause early damage. Commonly used sliding bearing materials include bearing alloys (also called Babbitt alloys or white clutch bearings factory alloys), wear-resistant cast iron, copper-based and aluminum-based alloys, powder metallurgy materials, plastics, rubber, hardwood and carbon-graphite, polytetrafluoroethylene (PTFE) ), modified polyoxymethylene (POM), […]

In actual condition monitoring, we often only need to judge the quality of rolling bearings and how long they can be used. If the power spectrum is not large, observe various frequency components in the spectrum. In order to get an accurate conclusion. When the vibration exceeded the vibration standard (such as the ISO2372 standard), […]

Countermeasures: You can find the manufacturer to replace.Countermeasures: Replace the upper and lower bearings and mechanical seals. Heating of the stator and rotor can also cause eccentricity. The damage of the upper bearing has little effect on the rotor. It is necessary to use precision instruments to detect and measure the bearing and shaft squatting.Countermeasure: […]

The gap of the labyrinth seal is too small (friction with the shaft); The teeth of the lock washer are bent (touch the bearing and cause friction); The position of the oil slinger is not suitable (it touches the flange cover and friction occurs); There are pits on the steel ball or roller (caused by […]
