Description

6201 2RS//6202 2RS//6204 2RS//6205 2RS water pumps used ball bearings,high sealing performance and low working noise.

1. Bearing abnormal operation condition and the corresponding countermeasures

conditions Speculate reasons measures

Abnormal temperature rise

 Grease too much or too little After checking, inject the right amount of lubricat
Load increased Adjust load, and modify bearing clearance or cooperate with clearance
Bad installation Improve the bearing process, installation accuracy, and the size of the prestressing force
Cooperate with surface peristalsis or bearing external friction Adjust precision or change the bearing

Big vibration

 Bad installation Fixed axis or shell with precision, and adjust the preload
Other things incasion Improve the shaft and shell surface cleanliness, and improve the installation way
Bearing wear or deformation Change the bearing
Oil leakage or discoloration Too much grease or seal rickety, outside oil, water invasion, etc Adjust the grease capacity or replace the seal form, and improve the bearing work environment
Big noise Bearing damage, peel, and clearance is too large Change the bearing
Other things invasion Clean parts, replace the seal device, and use clean grease

2. Common injury and corresponding countermeasures in bearings

Types Damage phenomenon Reasons Measures
Stripping Groove surface and part of the rolling surface have damage like fish scales Bearing internal clearance is too small. Improper or inadequate greaseAxial load changed Corrosion Bad installation Choose the suitable internal bearing clearance to choose lubrication method and grease. To select the supporting bearing axial clearance. Comprehensive anti-rust process to bearing. Establish a reasonable accuracy
Outer and inner ring fracture Interference larger , lager impact load stripping or burn extension. Cooperate with shaft or shell round is too large Choose the suitable cooperation. Set stable load rounded corners on cooperate surface is less than bearing corner
Electrolytic corrosion Rolling surface appears edm produce the melting point, and the sureface has a small indentation Current through the bearing produced sparks Implement insulation in bearing. Set current bypass not through bearing
Rust corrosion Bearing surface and roll surfaces are rusted Environment humidity is bigger. There is water or corrosion material into the inernal bearing Improve sealing device and improve bearing storage environment
Creep deformation Rings movement relative axis or axial shell Sleeve tighten is not enough. Interference shortage Appopriate strengthen. Increase the interference
Holder rupture There is distortion, wear and fracture Shock and torque is too large. Improper lubricant. Bad installation Reset load. To choose the suitable lubricant type. Reduce the installation error, improve installation method
