Introduction

Oil seals are critical components in machinery, designed to prevent the leakage of lubricants and contain pressure within a system. Among the various materials used for oil seals, Polyurethane (PU) stands out due to its exceptional properties and durability. This article examines the use of PU oil seals in machinery, highlighting their characteristics, applications, and solutions offered by WUSS Company.

PU Oil Seals in Machinery

PU oil seals are primarily used to safeguard machinery by providing an airtight barrier that prevents the leakage of lubricants and entry of contaminants. These seals are pivotal in maintaining the operational efficiency and longevity of mechanical systems.

Typically, PU oil seals are used in hydraulic systems, gearboxes, and engines where they endure significant rotational and translational motions. Their application extends to various sectors, including automotive, aerospace, and manufacturing industries.

PU Material Properties

Polyurethane is chosen for oil seals due to its durability, flexibility, and resistance to wear and tear. Key properties include:

• Hardness: Shore A scale ranging from 70 to 95.
• Tensile strength: Often exceeds 35 MPa, ensuring robust performance under stress.
• Temperature resistance: Operative between -40°C to 90°C.
• Chemical resistance: Stable against oils, solvents, and ozone.

These properties make PU oil seals suitable for demanding environments where traditional rubbers might fail.

Applications of PU Oil Seals

PU oil seals find usage across a variety of applications, including:

• Automotive engines: To seal in motor oil and prevent leakage.
• Hydraulic systems: Ensure the containment of hydraulic fluids under high pressure.
• Industrial machinery: Used in pumps and compressors to maintain pressure integrity.

The effectiveness of PU oil seals in these applications is attributed to their adaptability to dynamic conditions and resistance to degradation.
