CAT320 Center Joint Seal Kit OEM Grade Excavator Repair Parts Heavy-Duty Design Hydraulic Systems

Product Details

The CAT320 Center Joint Seal Kit utilizes ‌reinforced PTFE as the primary sealing material for wear resistance and low friction, paired with ‌rubber O-rings‌ for elastic compensation and bidirectional pressure adaptability. It operates under ‌≤30-40 MPa pressure‌ and withstands temperatures from ‌-30°C to +120°C‌, compatible with mineral hydraulic oils, fire-resistant fluids, water, air, and most lubricants. Designed for CAT320 excavators and compatible models (e.g., 320B/C/D), its ‌bidirectional sealing structure‌ features circumferential grooves to retain lubrication and reduce wear under dynamic rotations or oscillations. The kit excels in harsh environments (dust, humidity) and requires adherence to installation guidelines, including chamfer angles (15-20°), to ensure optimal performance in hydraulic swivel joints or rotating shafts.
