Understanding EN 853 2SN A Comprehensive Guide

Hoses are essential components in modern engineering and machinery, serving a multitude of purposes across various industries. Among the various types of hoses, the EN 853 2SN stands out as a vital option, especially for hydraulic applications. This article aims to provide a detailed understanding of the EN 853 2SN standard, its construction, applications, and why it is preferred in many hydraulic systems.

What is EN 853 2SN?

EN 853 is a European standard that specifies the requirements for low and medium pressure hydraulic hose lines. The 2SN designation represents a type of hose that consists of two steel wire braids, providing increased strength and flexibility. This hose is primarily designed for use with hydraulic fluids, including oil and water-based fluids, and is suitable for high-pressure applications.

Construction of EN 853 2SN Hoses

The EN 853 2SN hose is designed with several key components

1. Inner Liner The innermost layer is typically made from a rubber compound resistant to hydraulic fluids. This liner ensures that the hose can handle various fluids without deteriorating quickly.

2. Reinforcement The 2SN designation indicates that the hose has two layers of steel wire reinforcement. This braided structure provides exceptional tensile strength, allowing the hose to withstand high pressures without bursting.

3. Outer Cover The outer surface of the hose is made from a durable rubber compound that is resistant to abrasion, weathering, and ozone. This cover protects the inner layers from external damage while ensuring the hose remains flexible.

EN 853 2SN hoses come in a variety of sizes, typically ranging from 6 mm to 51 mm in inner diameter. The pressure ratings vary depending on the diameter and the specific application but can reach up to 400 bar (about 5800 psi), making them suitable for high-pressure hydraulic systems. The specific pressure capabilities will depend on the exact construction of the hose, including its materials and design.

Applications of EN 853 2SN Hoses

EN 853 2SN hoses find applications across a wide range of industries due to their durability and reliability. Some common uses include

1. Construction Equipment They are widely used in hydraulic excavators, backhoes, and bulldozers where high-pressure hydraulic systems are essential for operation.

2. Agricultural Machinery EN 853 2SN hoses are commonly found in tractors and combine harvesters, facilitating effective hydraulic power for various functions, including lifting and steering.

3. Industrial Machinery In manufacturing environments, these hoses are utilized in hydraulic presses, robotics, and conveyor systems where reliable hydraulic power is necessary.

4. Automotive Applications Some automotive systems utilize EN 853 2SN hoses for different hydraulic functions, including braking systems and power steering.

Why Choose EN 853 2SN Hoses?

There are several reasons why EN 853 2SN hoses are a preferred choice for hydraulic applications

- High Strength The dual steel wire braided design provides exceptional durability and resistance to pressure, making it suitable for demanding environments.
