Product Description

The 856-8M Hydraulic Seal is engineered for high-pressure systems, featuring a precision 10mm Shaft Seal Ring and a 720mm Rotary Gasket for robust rotary shaft sealing. Designed to withstand axial loads up to 500 bar and temperatures from -40°C to +150°C, it integrates directly with hydraulic pumps, motors, or rotary joints via standardized ISO 6194-compliant housings. The seal supports dynamic applications in heavy machinery, industrial automation, and marine equipment, offering low-friction performance with minimal leakage. Advantages include exceptional wear resistance and compatibility with diverse hydraulic fluids, though complex installation requires specialized tools. While lacking built-in electronics or battery components, its PTFE-based construction enables reliable operation under extreme conditions. The 720mm sealing diameter accommodates large rotating shafts, with a recommended radial clearance of 0.1-0.3mm for optimal performance. Detection systems typically monitor seal integrity within 1-2mm tolerance ranges during maintenance checks.
