Eaton has announced it has expanded its hydraulic hose portfolio with the release of a new high performing series.
The GH681 series is a one-wire braided hose qualified to one million impulse cycles, which provides mobile machinery customers with durability in harsh environments such as compact construction vehicles, agricultural machines, aerial lift platforms, and vehicles in the forestry industry.
Dimitar Atanasov, product manager, fluid conveyance products EMEA, said, “Standard EN857 Type 1SC hoses are qualified up to 200,000 impulse cycles. The Eaton GH681 exceeds this standard by five times and is designed to withstand the toughest applications. This durability helps decrease maintenance costs, improves safety and minimizes downtime.”
Used as part of a hydraulic system, the new hose works under pressure to transfer oil to the cylinders in mobile machinery like tractors, lifters and sweepers, while also being used for industrial applications like pressers to connect moving parts.
“Hydraulic system failures are serious business and can cost a lot. Hydraulic systems impulse cycles are key factors in a system effectivity, and a key measure in the life expectancy and overall quality of a hydraulic hose. Abrasion in the moving parts is the leading cause of hydraulic hose failures, so this is an area where Eaton focused when developing the new GH681 hose,” said Atanasov.
A Dura-Tuff cover provides up to eight times more abrasion resistance than an average standard synthetic hose cover, and while most hoses in the industry offer an operating temperature of 100°C, the Eaton GH681 was designed with higher pressure ratings and an operating temperature up to 126°C (260°F).
Typically hoses qualify for only a narrow range of pressure, and different hoses are needed for even smaller-difference pressure applications, but Eaton has enhanced this feature to enable customers to use this one-wire braided hose for a wider range of applications.
Increased operating temperature also allows for use in a broader range of hydraulic systems and offers additional protection against heat in demanding applications to extend service life.
