Gates also offer a full line of international thread ends for spiral-wire and wire-braid hoses.
As advanced hydraulic systems are designed and engineered into more and more high-powered, high-pressure equipment, the importance of high quality, flexible, durable hose assemblies that won't fail has never been more critical.
As the industry leader in hydraulic hose technology, Gates has developed an integrated solution to meet the needs of today's hydraulic systems – and tomorrows.
- Simplifies hose selection with constant pressure ratings
- Bends up to one-third the SAE specification
- Saves overall hose assembly length
- Facilitates easier plumbing and routing in tight applications
- Requires fewer bent tube fittings
- Eases installation with higher flexibility
- Lowers inventory requirements
- Extends life in bending, flexing applications
- Reduces costs by as much as 64 per cent
- Greater Performance, Reduced Costs and Downtime
As part of an integrated solution, the Gates MegaSys® hydraulic hose and coupling system offers a combination of technology, performance and flexibility that is unmatched by anything on the market today. Most manufacturers use the minimum SAE specifications as their performance benchmark, Gates aim much higher.
For impulse life, the wire-braid hose is tripled to 600,000 cycles and the spiral-wire is doubled to 1,000,000 cycles, that's 3 and 2 times the SAE specification. Even more remarkable is the tests are conducted at tight bend radii; the spiral-wire hose is up to half the SAE minimum bend and the wire-braid hose to one third the minimum bend. This means extended hose life, more flexibility, easier, tighter routing and an overall lower cost of ownership. Ideal for mining applications, MegaSys® is both FRAS and MSHA approved.
Simplified hose selection – constant pressure, colour coding
Just as hydraulic systems have one pressure across the entire circuit, MegaSys® simplifies hose selection by providing one pressure across a complete range of sizes. Colour coding is used to make the selection even easier, one colour for each pressure. The available MegaSys® pressures are 3250 PSI (blue), 4000 PSI (purple), 5000 PSI (red), 6000 PSI (orange) and 8000 PSI (yellow). The MegaSys® constant pressure range makes for easier and safer identification in service.
Spiral-wire and wire-braid hose
MegaSys® spiral-wire hoses feature four alternating or six layers of spiraled, high tensile steel. The nitrile tube is tough enough to handle aggressive biodegradable fluids and has significant less permeation than neoprene tubes when used with petroleum based oils. Spiral-wire hose temperature compatibility ranges from -40°C to +121°C.
MegaSys® wire-braid constant pressure hoses feature two braids of high tensile steel wire with nitrile tubing suitable for use with biodegradable hydraulic fluids. Wire-braid hose temperature compatibility ranges from -40°C to +100°C.
A primary cause of hose failure on fluid power equipment is cover abrasion resulting from cuts, friction caused by other moving parts or from mechanical impacts. Exposed hose reinforcement is susceptible to rust and accelerated damage leading to failure. Gates abrasion resistant covers have been tested and found to last up to 300 times longer than standard rubber covers. The MegaSys® hydraulic hoses are available with XtraTuff™ or MegaTuff® abrasion resistant covers. Abrasion resistant covers increase service life, lower maintenance and replacement costs and eliminate the need for costly hose protectors such as spring guards and nylon sleeves.
Gates MegaCrimp® and GlobalSpiral™ Couplings
The majority of hydraulic hose failures occur at the couplings, due to blow-offs or leaks. Gates has designed and engineered innovative, robust couplings specifically designed to crimp on Gates MegaSys® hoses for guaranteed leak-free performance. With hose, couplings and assembly equipment from one manufacturer, all designed as an integrated solution, the greatest operator safety is ensured whilst plant downtime is reduced. Gates MegaSys® complies with the Guideline for Fluid Power System Safety at Mines, MDG41.
