Seal Washer 0661102000 is a high-performance sealing component engineered exclusively for hydraulic rock drills—the core equipment in mining, quarrying, and construction rock drilling operations. Designed to meet the rigorous demands of high-pressure hydraulic systems with operating pressures up to 35 MPa, this precision-machined seal washer delivers uncompromising leak-proof performance, preventing hydraulic fluid seepage and safeguarding critical drill components such as piston rods, cylinder heads, and hydraulic valves from contamination, corrosion, and premature wear. Unlike generic sealing washers, this part is tailor-made for hydraulic rock drill applications, ensuring it can withstand the harsh operational environments that are common in underground mines, open-pit quarries, and foundation drilling sites.
Crafted from premium nitrile butadiene rubber (NBR) blended with high-strength carbon steel reinforcement, the 0661102000 seal washer excels in extreme working conditions—including high vibration from continuous drilling, variable temperature fluctuations ranging from -20°C to 120°C, and heavy-duty continuous operation typical of mining sites. Its tight dimensional tolerance of ±0.02 mm ensures a perfect interference fit with hydraulic rock drill assemblies, eliminating the risk of pressure loss that can cause drill inefficiency, reduced drilling speed, or unexpected downtime during critical production shifts. The rubber surface is treated with a special anti-aging coating, which extends the part’s service life by 30% compared to standard seal washers, while the steel core provides structural stability to resist deformation under high pressure.
As a direct replacement part, the Seal Washer 0661102000 is compatible with a wide range of leading hydraulic rock drill models, including but not limited to Atlas Copco, Sandvik, and Boart Longyear units. This compatibility streamlines maintenance workflows for mining contractors and equipment service providers, eliminating the need for custom modifications or costly aftermarket adaptations. Whether you are performing routine preventive maintenance, scheduled component overhauls, or emergency on-site repairs, this seal washer guarantees reliable sealing performance from the first installation, reduces equipment downtime by minimizing replacement frequency, and lowers long-term operational costs by cutting down on fluid waste and component repair expenses.
We prioritize quality and consistency in every unit, ensuring that each 0661102000 seal washer undergoes strict quality control tests, including pressure resistance testing, dimensional inspection, and material compatibility verification, to meet international industry standards such as ISO 9001 and API 7K. Ideal for large-scale mining projects, aggregate quarrying operations, and civil engineering infrastructure construction projects, our seal washer is a trusted choice for businesses seeking durable, high-performance hydraulic rock drill spare parts that balance cost-effectiveness with uncompromising quality. We also offer flexible bulk ordering options and on-time delivery services to support the continuous production needs of mining and construction enterprises worldwide, ensuring that you never face delays due to missing or worn-out sealing components.
