Construction Machinery Multi-hole End Cap

When you're dealing with hydraulic systems and gearboxes in the construction industry, a failure is never just a part-it's an entire job site coming to a halt. Our Construction machinery multi-hole end cap is built to withstand the high-pressure, high-vibration world of excavators and loaders. Since 1997, we've refined our heat treatment and machining processes. We produce the Construction machinery multi-hole end cap using high-strength HT250 or QT450-10 cast iron, ensuring it remains stable under pressures up to 35MPa.

Precision in hole placement is everything for a Construction machinery multi-hole end cap. We utilize 40+ CNC machines to ensure that bolt holes and oil passages align perfectly with your hydraulic pumps or gearboxes. Our caps feature IT7-IT8 grade hole tolerances and a sealing surface flatness of ≤0.03mm to guarantee zero leakage. Being a primary supplier to Sany Heavy Industry has taught us the importance of rigorous management; our 100% inspection protocols ensure that every cap we ship is ready to perform in the dustiest, heaviest construction environments.
