Key performance requirements for Atlas Copco Air compressor Roller Bearings:
Thermal resistance: During operation of the air compressor, the bearing temperature may rise (especially for high-pressure models), so bearings that can withstand temperatures ranging from 80 to 120°C or even higher must be selected.
Wear resistance: High-strength bearing steel (such as GCr15) should be used, and it should undergo quenching treatment to increase surface hardness and wear resistance.
Sealing: Some bearings are equipped with dust covers or sealing rings to prevent lubricating oil leakage and the intrusion of dust, water vapor, and extend service life.
Precision grade: High-speed rotating components (such as screw rotors) require bearings with a P5 grade or higher precision to reduce vibration and noise.
Maintenance precautions:
Lubrication management: Regularly check the quantity and condition of lubricating grease/oil, and replace them as per the manual (usually once every 1,000-2,000 hours), to avoid overheating or wear due to poor lubrication.
Gap inspection: If abnormal vibration, noise, or temperature increase occurs during operation, it may indicate excessive bearing clearance or wear. It is necessary to disassemble and inspect promptly, and replace if necessary.
Installation specifications: When installing, use specialized tools to avoid striking the outer ring or rolling elements of the bearing, ensure coaxiality, and prevent early damage due to improper installation.
Environmental protection: For air compressors used in dusty and humid environments, strengthen the sealing protection of the bearing area to prevent contaminants from invading.
When choosing Atlas Copco Air compressor Roller Bearings, it is necessary to consider the type of Atlas Copco air compressor (piston type, screw type, etc.), rotational speed, load characteristics, and working conditions, and refer to the original factory specification parameters to ensure the matching of the bearings with the equipment and the service life.
