Recommended Materials
Heavy Equipment & Mining Machinery Sealing Performance & Engineering
Heavy earthmoving equipment, hydraulic excavators, wheel loaders, mining haulers, and agricultural tractors operate in the harshest outdoor environments on Earth. Extreme dust, sub-zero cold, scorching sun, and severe shock loads demand rugged, resilient elastomeric solutions.
Operating Challenges
- Abrasive Mud, Rock Dust & Moisture: Reciprocating chrome cylinder rods constantly drag sharp rock particles, sand, and mud toward internal glands.
- High Peak Shock Pressures: Hydraulic cylinders experience pressure spikes exceeding 500 bar when buckets strike hard rock.
- Severe Mechanical Vibration: Engines, gearboxes, and cabs require heavy-duty vibration isolators to prevent metal fatigue.
Engineered Solutions
Heavy Polyurethane Wiper Scrapers
Tough 95 Shore A polyurethane wiper rings that scrape away caked mud and ice without scoring the rod.
Multi-Lip Chevron Packings
Reinforced fabric and elastomer Vee-packing sets that self-energize under heavy load.
Rubber-to-Metal Bonded Engine Mounts
Heavy shear-and-compression elastomeric buffers that isolate cab operators from frame vibration.
