Common Types and Functions Shaft Sleeve: Protects the shaft journal, provides a wear-resistant surface, and facilitates maintenance and replacement; often used in conjunction with oil seals. Oil Seal / Oil Cap: Prevents the leakage of lubricating oil along the shaft, the material is usually nitrile rubber (NBR) or fluororubber (FKM), with a double lip design that can scrape off oil and prevent dust. Shaft Sleeve / Shaft Seal Kit: Includes a shaft sleeve + oil seal + related installation parts, providing a one-step solution with good compatibility.

Common Misconceptions and Risks Replacing only the oil but not the filter: Impurities accumulate, accelerating wear and clogging. Overdue use: Increased pressure difference leads to higher energy consumption and an increased risk of filter damage. Installation too tightly: May cause the base to deform or make future disassembly difficult.

Key points for replacement and maintenance: When replacing, the oil separator filter element should be replaced simultaneously. Also, check if the sealing gasket is aged. If necessary, replace it together to ensure a proper seal. Before installation, clean the oil stains and impurities on the interface surface. Tighten according to the specified torque to avoid over-tightening which may cause the shell to deform or under-tightening which may lead to leakage. Regularly (usually in accordance with the filter element replacement cycle, approximately 2000-4000 hours) check if there are any cracks, corrosion or deformation in the shell. Replace it promptly if any abnormalities are found.

Strict model matching: Different series of Atlas Copco air compressors (such as fixed type, mobile type, screw type, etc.) may require different specifications of coolant. Please select the corresponding original factory coolant based on the specific model of the equipment (such as GA75, XAS186, etc.). For example, some models use long-lasting coolant, with a replacement cycle of up to 8,000 - 10,000 hours. It is not allowed to mix this coolant with other brands or types of coolant at will.

Replacement Precautions Before installation, clean the oil stains and impurities on the interface surface to avoid scratching the sealing ring. Ensure a proper installation to avoid distortion or excessive stretching, which may affect the sealing effect. It is recommended to conduct regular checks and replace it in a timely manner according to the usage environment (such as humidity, temperature, and medium). Generally, it is advisable to replace it synchronously with the equipment maintenance cycle.

Note: Replacement cycle: The sealing ring is a wear-prone component. It is recommended to conduct regular inspections and replacements as per the instructions in the equipment maintenance manual to prevent leakage due to aging or wear, which could cause equipment malfunctions.
