Understanding EN 857 2SC Hydraulic Hoses Specifications and Applications

Hydraulic hoses are critical components in hydraulic systems, playing a vital role in the transmission of fluid power and ensuring the effective functioning of machinery across various industries. Among the numerous standards available for hydraulic hoses, the EN 857 2SC specification stands out due to its robust design and wide array of applications. This article delves into the key features, specifications, and typical uses of EN 857 2SC hydraulic hoses.

What is EN 857 2SC?

The EN 857 2SC standard falls under the European Norm (EN) standards, which provide guidelines for the construction and performance requirements of hydraulic hoses. Specifically, the 2SC designation refers to a type of wire-reinforced hose known for its effectiveness in handling high-pressure applications. The 2 indicates that the hose includes two layers of steel wire braiding, enhancing its tensile strength and providing better burst resistance. The SC denotes the smooth cover, which offers improved flexibility and resistance to abrasion, making it suitable for various environmental conditions.

Key Specifications

1. Construction EN 857 2SC hoses typically consist of three layers an inner tube made from synthetic rubber designed to withstand hydraulic fluids, an intermediate layer composed of two steel wire braids, and an outer cover that is also crafted from synthetic rubber.

2. Pressure Rating The pressure ratings for EN 857 2SC hoses can vary depending on the size. Generally, these hoses have a nominal pressure range from 140 bar to 250 bar, but specific applications may require hoses with different ratings.

3. Temperature Resistance EN 857 2SC hoses are designed to operate effectively within a temperature range of -40°C to +100°C. This temperature tolerance makes them suitable for usage in both high-temperature and low-temperature environments.

4. Fluid Compatibility These hoses are typically compatible with water-based fluids and mineral oil-based hydraulic fluids, making them versatile options for a wide range of applications in heavy machinery, agriculture, and construction.

Due to their robust construction and high pressure rating, EN 857 2SC hydraulic hoses find application in various sectors

1. Construction and Mining Heavy equipment such as excavators, bulldozers, and mining machinery rely on EN 857 2SC hoses to efficiently transmit hydraulic power for movement and other operational functions.

2. Agriculture In agricultural machinery, these hoses are indispensable for hydraulic systems used in tractors, harvesters, and plows, enabling the machinery to perform various tasks such as lifting, digging, and seeding.

3. Industrial Manufacturing In industrial settings, hydraulic systems often use EN 857 2SC hoses to facilitate the movement of materials, control press operations, and automate machinery.

4. Automotive and Transportation Hydraulic systems in vehicles, particularly those with advanced braking systems and power steering, frequently utilize EN 857 2SC hydraulic hoses for their reliability and pressure ratings.

Conclusion

EN 857 2SC hydraulic hoses are vital components in numerous applications that demand high performance, reliability, and flexibility. Their dual-layer steel wire reinforcement ensures they meet rigorous industry standards for pressure and durability, making them an indispensable choice in sectors ranging from construction to agriculture. When selecting hydraulic hoses, understanding the specifications and benefits of standards like EN 857 2SC is essential for ensuring the efficiency and safety of hydraulic systems. Investing in quality hoses is not merely a choice but a necessity for enhancing productivity and prolonging the life of equipment.
