INA Stainless Steel Bearing Deformation Maintenance Solution

The phenomenon of size or shape change of INA stainless steel bearings or components due to stress is called deformation. Due to harsh working conditions, the mechanical equipment at the production site is often overloaded and it is very common for some bearings to deform. Their deformation will accelerate the wear and even breakage of other related parts, and may also cause damage to the system series bearings or the entire equipment, causing equipment accidents, so the harm of deformation is quite serious.
The deformation of INA stainless steel bearings when the applied stress is less than the material yield strength is called elastic deformation. Plastic deformation, also called permanent deformation, refers to the deformation of the bearing parts that cannot be restored after the external force (load) is removed. Excessive deformation is an important type of mechanical equipment failure.

1. Use reasonable cooling methods:
   The influence of the cooling process on deformation after metal quenching is also a very important cause of deformation. Hot oil quenching has smaller deformation than cold oil quenching, and is generally controlled at 100±20°C. The cooling ability of the oil is also critical to deformation. The stirring method and speed of quenching affect the deformation. The faster the cooling speed of metal heat treatment, the more uneven the cooling, the greater the stress generated, and the greater the deformation of the mold.
2. Use appropriate media:
   Under the premise of ensuring the same hardness requirements, try to use oily media. Experiments and practice have proven that, provided there is no difference in other conditions, the cooling rate of oily media is slower, while the cooling rate of water-based media is relatively faster.
3. The parts structure must be reasonable:
   During the cooling process after metal heat treatment, the thin parts always cool faster and the thick parts cool slower.
   The vibration measurement of INA stainless steel bearings reflects that the damage of bearing vibration to bearings is very serious. Therefore, the size of the vibration can be measured by using a special bearing vibration measuring instrument (frequency analyzer, etc.). Through frequency sub-measurement Very specific circumstances. Since the measured values vary depending on the operating conditions of the bearing or the installation location of the sensor, it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard.
