Not all damaged bearings can be corrected, but the cause and extent of the damage to each damaged bearing must be evaluated to prevent or reduce further damage before considering the correction or replacement of a new bearing. There are many causes of bearing damage, such as improper equipment, dirt intrusion or moisture inses, etc., which are common causes of early damage to many bearings.
The following is an analysis of some of the common causes of damage to large bearings and the corresponding preventive measures that can extend the life of the bearing:
Improper operation
Improper installation, handling or disassembly may cause deformation or mutilation of the cagePrecautionary measures: Use appropriate handling, equipment and disassembly tools.
Smooth is not sufficient
Bearing deformation precautions that may result in abrasion of components due to insufficient or improper smoothing may be severe: improve the smoothing system and make up for or replace the smoothing agent appropriately and punctually.
Rust and corrosion
Touching water may cause the bearing elements to wear out and rust. Corrosion-damaged bearings may fall off during operationPrecautionary measures: Check the seals regularly to ensure excellent sealing and correct storage of the bearings.
current
Electrification of the bearing while rotating may result in grooves or notches. Improper grounding of electrical operation while the bearing is stationary can lead to a subtle burn precaution: reduce or prevent current from passing through the bearing by means of a proper grounding connection before welding a component other than the bearing.
External Materials
Abrasive particle contamination and debris ingress can lead to bearing face wear, abrasion and saggingPrecautions: Remove ingress particles and debris, replace smoothing agents, and look at the sealing system.
Migraines
Migraines, tilts or excessive loads may lead to geometric stress concentrations or surface detachment Precaution: Accurate machining of housings and abutments

Troubleshooting of high-frequency pressure sensors during operation
1. When the pressure goes up, the output of the transmitter can't go up.
In this case, you should first check whether the pressure connection is leaking or blocked. If you admit that it is not, check the wiring method and check the power supply, if the power supply is normal, then briefly pressurize to see if the output changes, or observe the zero position of the sensor ...

What are the characteristics of smart sensors?
1. High precision and high quality
Assuming that the data information collected by the sensor makes a mistake, it is equivalent to making a mistake from the source, and the transmission, analysis and use of all the data behind it are meaningless, so the accuracy and quality of the sensor are guaranteed.
