0506010008 Atlas Copco Air compressor Roller Bearing

Atlas Copco Air compressor Roller Bearing Main Types and Application Scenarios

Spherical roller bearings

Applicable to: Rotating components such as motor rotors and fan shafts that mainly bear radial loads.

Features: Simple structure, low friction coefficient, capable of simultaneously bearing certain radial and axial loads, and allowing higher rotational speeds.

Cylindrical roller bearings

Applicable to: Parts that bear large radial loads, such as crankshafts.

Features: Strong radial load-bearing capacity, large contact area between the rolling elements and the raceways, suitable for high-load conditions, but not suitable for bearing axial loads.

Angular contact ball bearings

Applicable to: Rotors of screw-type air compressors and other components that need to bear both radial and axial loads simultaneously.

Features: Capable of withstanding large unidirectional axial loads, can withstand bidirectional axial forces through paired installation, high precision, suitable for high-speed operation.

Cone roller bearings

Applicable to: Parts such as the crankshaft end of piston-type air compressors that bear combined loads.

Features: Can bear both radial and axial loads simultaneously, has a large load-bearing capacity, but has a relatively lower rotational speed, and the clearance needs to be adjusted during installation.

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 equipmen
