 Oil seals are vital components in mechanical equipment, playing a crucial role in preventing oil or other liquids from leaking, thus ensuring the normal operation of machines. The choice of oil seals directly affects the efficiency, lifespan, and maintenance cost of the equipment. So, what key points should be considered when purchasing oil seals? This article will provide a detailed analysis from multiple perspectives.

 1. Basic Requirements of Oil Seals

 The primary function of an oil seal is to maintain an excellent sealing performance while ensuring long-term stability during equipment operation. A good oil seal should meet the following basic criteria:

 High-temperature resistance: Oil seals need to operate in high-temperature environments, especially in industrial machinery. It’s important to know the temperature tolerance of the oil seal material to ensure it can maintain good sealing performance at high temperatures.

 Wear resistance: Oil seals are exposed to wear over time, especially when in contact with rotating shafts or other moving parts. A wear-resistant oil seal ensures a longer lifespan.

 Corrosion resistance: Oil seals often come into contact with oil, chemicals, or other corrosive substances. Thus, the material needs to have good corrosion resistance.

 Resistance to oils and chemicals: Oil seals must be able to withstand exposure to oils, lubricants, and chemicals without degrading.

 2. Material Selection of Oil Seals

 There are many types of materials available for oil seals, each offering unique advantages and suitable applications. When purchasing oil seals, selecting the right material is critical to ensuring their reliability:

 Nitrile Butadiene Rubber (NBR): Widely used in general machinery applications, NBR offers excellent oil resistance, wear resistance, and water resistance. It is ideal for environments with temperatures not exceeding 100°C.

 Fluoroelastomer (FKM): Suitable for high-temperature and high-pressure environments, FKM offers exceptional resistance to heat and chemicals, making it ideal for automotive and aerospace applications.

 Polyurethane (PU): Excellent wear and tear resistance, PU is ideal for high-load and high-impact applications.

 Selecting the right material depends on the working environment and the specific needs of the equipment. Matching the material correctly will improve the sealing effect and reduce maintenance costs.

 3. Working Environment of Oil Seals

 The performance of oil seals is closely related to the working environment. Different environments require different characteristics from the oil seal:

 Temperature: The temperature range is a key factor when choosing oil seals. If the operating environment involves high temperatures, high-temperature resistant materials like FKM or polyurethane should be chosen.

 Chemical Exposure: If the oil seal will be exposed to chemicals, selecting materials resistant to chemical corrosion, such as FKM or PTFE, is essential.

 Pressure: Some equipment operates under high-pressure conditions. Oil seals used in these environments must have higher pressure resistance, such as polyurethane or FKM.

 5. Supplier Services and Support
