Frequently Asked Questions (FAQs)

# How Do I Measure Oil Seals?

When measuring oil seals, you need to focus on three key dimensions: the inside diameter (ID), the outside diameter (OD), and the width or thickness. For example, a seal marked as 70 90 10 indicates a 70mm shaft, a 90mm bore, and a 10mm width.

# What is the Operating Temperature Range of Oil Seals?

The operating temperature range of oil seals depends on the material. For instance, FKM seals can handle up to 200°C, while NBR seals should not exceed 90°C. HNBR seals offer good cold resistance and can handle up to 150°C.

# Why Do Oil Seals Leak?

Oil seals can leak due to several reasons, including improper installation, contamination, and roughness on the shaft or bore. Ensuring clean storage conditions and even pressure during installation is crucial to prevent leakage.

# How Often Should I Replace Oil Seals?

The replacement frequency of oil seals varies based on the application. For example, automobile oil seals can last up to 100,000 km, while industrial oil seals typically last 1.5 to 2 years. PTFE seals have a shorter service life and need to be evaluated based on the environment.

# What Factors Should I Consider When Choosing an Oil Seal?

When selecting an oil seal, consider factors such as dimensions, pressure, temperature, type of fluid, lubricant, and shaft speed. Understanding these parameters helps you choose a seal that can withstand the specific conditions of your application.
