🚜 1. Excavator Sealing Systems
Excavators require high-performance sealing in hydraulic and mechanical systems due to constant movement and pressure changes.
Typical applications include:
Boom cylinder seals
Arm cylinder seals
Bucket cylinder seals
Swing motor seals
We provide hydraulic seals designed for high pressure, wear resistance, and long service life.
🚜 2. Loader & Bulldozer Systems
Wheel loaders and bulldozers operate under heavy load and abrasive conditions.
Applications include:
Hydraulic cylinder sealing
Gearbox oil seals
Axle sealing systems
Our sealing solutions help reduce downtime and improve machine reliability.
⚙️ 3. Hydraulic System Sealing
Hydraulic systems are the core of construction machinery, requiring precise sealing performance.
Applications include:
Hydraulic cylinders
Control valves
Pumps and actuators
We provide rod seals, piston seals, and guide rings for stable hydraulic operation.
🧱 4. Undercarriage & Drive Systems
Undercarriage components are exposed to dust, mud, and high impact loads.
