Understanding the 25x35x7 Oil Seal A Detailed Guide

Oil seals, also known as shaft seals, play a crucial role in various mechanical systems by preventing the leakage of lubricants and contaminants. Among the different types of oil seals available in the market, the 25x35x7 oil seal is a specific size that serves a variety of applications. This article will delve into the specifications, materials, functions, and applications of the 25x35x7 oil seal.

Specifications

The numbers in the designation 25x35x7 represent the seal’s dimensions the first number (25 mm) indicates the inner diameter, the second number (35 mm) signifies the outer diameter, and the last number (7 mm) denotes the thickness of the seal. These measurements are essential in ensuring that the oil seal fits properly within the designated casing or housing, providing an effective barrier against leaks.

Materials

Oil seals are typically made from a variety of materials, each suited to specific applications. Common materials include

1. Nitrile Rubber (NBR) Known for its resistance to oil and abrasion, NBR is frequently used for standard oil applications where moderate temperatures and pressures are present.

2. Fluoroelastomers (FKM) These are utilized in high-temperature and chemical environments. They exhibit superior resistance to high temperatures, making them ideal for more demanding applications.

3. Polyurethane This material offers excellent abrasion resistance and is often used in heavy-duty environments.

When selecting an oil seal, it’s essential to consider the operational environment and the type of lubricants used, as this will influence the choice of material.
