DIN EN856 SAE R13 R15
SAE 100 R13 and R15 ultra-high pressure four-layer or six-layer wire-wound hydraulic hoses are reinforced with multi-layer high-strength steel wire winding.. They represent the highest pressure rating in the SAE 100R series, specifically designed for extremely harsh operating conditions, capable of withstanding extremely high system pressure, intense pressure shocks and pulses.
- Product Introduction
SAE 100 R13 and R15 are ultra-high pressure four-layer or six-layer wire wound hydraulic hoses reinforced with multi-layer high strength steel wire winding. They are the highest pressure rating in the SAE 100R series. They are designed for very harsh operating conditions, and can withstand extremely high system pressure, as well as severe pressure shocks and pulses. These two types of hoses are strictly complied to SAE J343 and the best option for ultra-high pressure hydraulic systems of heavy construction machinery, mining equipment and large presses, etc.
Product Structure And Features
R13 and R15 have similar multi-layer composite structures, but the specific design of the steel wire winding layer determines their different performance emphases.
Inner rubber layer
It is made of oil-resistant and wear-resistant synthetic rubber, with excellent compatibility with petroleum-based hydraulic oil, bio-oil, etc., so as to ensure the purity and sealing of fluid transportation under high pressure.
Enhancement Layer (Core difference)
SAE 100 R13
The winding is made of four or six layers of high strength steel wire. Usually, arranged in a "tightly wound" manner of its steel wires, which makes the outer diameter of the hose relatively smaller, lighter and more flexible, while performing well in maintaining ultra-high pressure resistance.
Enhancement Layer (Core difference)
SAE 100 R15
It also needs four or six layers high strength steel wire winding layers. Its steel wires are typically coiled at "fixed intervals" The structure has a unique resistance to pulse fatigue and is particularly adapted for operation under conditions of severe pressure shocks and pulses, and has an extremely long service life.
Outer rubber layer
Outer Rubber Covering
Made of synthetic rubber. Super wear resistant, weather resistant and ozone resistant. The outer layer is thick and strong enough to withstand the most extreme physical and environmental damage, providing the ultimate protection for the internal steel wire reinforcing layer.
Core Features
Ultra-high pressure resistance
Multi-layer steel wire winding structure is very high burst pressure, suitable for ultra-high pressure system.
Outstanding anti-pulse performance
Especially R15, designed to provide the best resistance to pressure shock and pulse fatigue. With extremely long service life.
Outstanding flexibility
(R13 stands out)
The tight winding structure of R13 realizes a smaller outer diameter and better flexibility at the same pressure level, which is convenient for installation in compact spaces.
Ultimate durability
The super strong outer rubber and steel wire frame can endure extreme wear and tear, impact and harsh environments.
Low bending radius
It is an ultra high pressure hose, but gives excellent bending performance.
