5. FAQ

Q: What are the key technical specifications, such as pressure rating, temperature range, and expected service life under different working conditions?
A: This heavy-duty oil seal kit is engineered for rigorous hydraulic system demands. Its maximum working pressure is 550 bar, suitable for high-pressure systems in large excavators. The operating temperature range spans -45°C to +135°C, accommodating cold northern winters and hot tropical summers. Under normal medium-load conditions (≤300 bar, 40–80°C), the service life reaches 9000–11000 working hours. In harsh environments (heavy dust, frequent impact loads, or continuous high-temperature operation), it still achieves 6000–7000 working hours, which is 70–90% longer than standard single-material seal kits. The FKM O-rings alone maintain elasticity for over 12,000 hours under normal conditions.

Q: What specific installation steps and critical precautions should be followed to ensure optimal performance and longevity?
A: Proper installation is vital for seal kit performance. First, completely disassemble the cylinder and clean all parts (grooves, rod, bore) with clean hydraulic oil—remove all old seal debris, metal shavings, and dirt; even tiny particles can damage new seals. Second, inspect the piston rod and cylinder bore for scratches, dents, or corrosion; repair or replace damaged parts before installation. Third, lubricate all new seals and O-rings with clean hydraulic oil; never use grease or petroleum-based lubricants, as they cause rubber swelling. Fourth, install seals in the correct orientation (rod seal lip faces pressure side; piston seal open side faces piston head); use installation tools to avoid twisting or damaging seals. Fifth, fit wear rings and backup rings tightly into their grooves, ensuring no gaps. Finally, after assembly, test the cylinder at low pressure first to check for smooth movement and leaks before full-pressure operation.

Q: How is the kit packaged, and what are the recommended storage conditions to preserve component quality?
A: Each 2.180-00888 oil seal kit is individually sealed in a transparent, oil-resistant plastic bag with a labeled component list for easy identification. The bag is placed in a sturdy cardboard box with foam padding to prevent component deformation or damage during transportation. For storage, keep the kit in a cool, dry, dark warehouse away from direct sunlight, heat sources, ozone, and corrosive chemicals. The ideal storage temperature is 12–25°C, with relative humidity below 65%. Avoid stacking heavy items on the boxes. Proper storage maintains component elasticity and dimensional stability, extending the shelf life to up to 3 years without performance degradation.
