Punching Machine Fixed Washer C110000978 is a precision fastener component engineered exclusively for Hydraulic Rock Drills, tailored to the harsh conditions of underground mining and drilling operations. It addresses the industry’s core pain points: uneven pressure distribution, component loosening from high-frequency vibration, and rapid wear due to abrasive debris.
Crafted with high-grade Q235B carbon steel through cold-rolled forming and heat treatment (tempering at 600℃), the washer achieves exceptional flatness with a tolerance of ±0.02mm, ensuring full contact with mating surfaces. Its surface is coated with electrophoretic paint, passing 72-hour salt spray tests to resist corrosion from underground moisture and mineral-rich dust. The washer’s thickened edge design (1.5mm thicker than standard washers) enhances shock absorption, reducing the impact of hydraulic rock drill operation vibrations on fastened components.
Beyond basic pressure distribution, it prevents local stress concentration— a common cause of bolt loosening and component deformation in high-load drilling scenarios. Punching Machine Fixed Washer C110000978 undergoes strict ISO 9001 quality control: each unit is inspected for flatness via laser measurement, wear resistance through friction testing (≥5000 cycles without deformation), and dimensional accuracy with digital calipers. It offers universal compatibility with most standard Hydraulic Rock Drill models, including Atlas Copco FlexiROC M9/M10 and Sandvik DP1500, eliminating the need for custom modifications.
Installation is hassle-free with a direct replacement design that matches original equipment specifications—no special tools required, reducing maintenance downtime for mining teams. Backed by a 12-month warranty, this washer is a cost-effective solution for mining companies and maintenance workshops, as it extends the service life of paired components (e.g., bolts, cylinder flanges) by 40% compared to generic washers. Whether used in deep underground mines or open-pit drilling sites, it ensures stable component fixation, minimizes operational failures, and maximizes the overall efficiency and safety of Hydraulic Rock Drill systems.
