Understanding EN 853 2SN A Comprehensive Guide

When it comes to hydraulic systems, the selection of the appropriate hose is vital for ensuring efficient and safe operation. One common standard used in the industry is EN 853 2SN. This standard is part of the European Committee for Standardization (CEN) guidelines, which ensures that various products, including hydraulic hoses, meet specific safety and performance criteria. In this article, we will explore the details of EN 853 2SN, its specifications, applications, and the advantages of using hoses that meet this standard.

What is EN 853 2SN?

EN 853 2SN refers to a specific type of hydraulic hose defined by the European Standard (EN) 853. The '2SN' indicates a two-wire braided hydraulic hose, which is designed for high-pressure applications. The hose is constructed with two layers of steel wire braiding, which provides significant strength and resistance to pressure and mechanical stress.

The full designation is typically broken down as follows

- EN 853 Indicates that the hose conforms to the European Standard for hydraulic pressure hoses. - 2 Denotes that the hose has two layers of steel reinforcement. - SN Stands for 'Smooth/Nylon,' referring to the smooth cover finish and the type of internal material.

The EN 853 2SN hoses are characterized by their ability to operate under high pressure, typically rated up to 400 bar (5800 psi), depending on the inner diameter. These hoses are available in various diameters, typically ranging from 6mm to 51mm, making them suitable for a wide variety of applications.

Additionally, these hoses are designed to provide excellent flexibility and bend radius, essential for applications where space is limited and requires system adaptability. The cover of the hose is usually made from oil-resistant synthetic rubber, providing protection against external elements like abrasion, weathering, and various chemicals.

Applications of EN 853 2SN

Due to their high-pressure capabilities and durability, EN 853 2SN hoses are widely used in various industries, including

1. Construction Hydraulic hoses are critical in heavy machinery like excavators, bulldozers, and cranes. Robust hoses ensure the safe transfer of hydraulic fluids, enabling machinery to operate efficiently in rugged environments.

2. Agriculture Farming equipment often requires hydraulic systems to operate tractors and other machinery. EN 853 2SN hoses help in the smooth functioning of these systems, ensuring timely and efficient agricultural practices.

3. Automotive In the automotive industry, these hydraulic hoses are often used in braking systems and power steering components, where high-pressure hydraulic fluid is necessary for optimal performance.

4. Manufacturing Various manufacturing tools utilize hydraulic systems for production processes. The durability and resilience of EN 853 2SN hoses cater to the demands of manufacturing environments.

Advantages of EN 853 2SN Hoses

1. High Pressure Resistance The primary advantage is the ability to withstand high pressure, which is crucial for safety and performance in hydraulic systems.

2. Flexibility With a relatively small bend radius, these hoses can be routed through tight spaces, making them versatile for various installations.

3. Durability Constructed to resist abrasion, oil, and weathering, EN 853 2SN hoses are built to last, reducing the frequency of replacements.

4. Standardization Compliance with EN 853 ensures that users are getting a hose that meets strict safety and performance criteria established by the European Committee for Standardization.

Conclusion

In conclusion, EN 853 2SN hoses play a pivotal role in hydraulic applications across multiple industries. Their high-pressure capacity, flexibility, and durability make them a preferred choice for many engineers and technicians. Understanding these hoses and their specifications can significantly impact the efficiency, safety, and reliability of hydraulic systems. When considering hydraulic hose options, opting for hoses that meet the EN 853 2SN standard can lead to better performance and reduced downtime in various applications.
