　　Metric oil seal, also known as a shaft seal or rotary shaft seal, is a type of seal used to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. These seals are designed to prevent leaks while also preventing the ingress of contaminants such as dirt, dust, and water. 　　Metric oil seals are similar to other types of oil seals, but they are sized according to the metric system. This means that their dimensions are specified in millimeters rather than inches. Metric oil seals are commonly used in applications where metric-sized shafts and housings are used. 　　Like other types of oil seals, metric oil seals typically consist of a sealing element, a inner metal, and a spring. The sealing element is usually made of an elastomeric material such as rubber or silicone, which provides a flexible seal between the shaft and the housing. The inner metal provides structural support for the seal, while the spring helps to maintain contact between the sealing element and the shaft. 　　When selecting a metric oil seal, it is important to consider factors such as the operating conditions, the design of the seal, and the materials used. Different materials offer different levels of resistance to heat, chemicals, and other environmental factors, making them suitable for use in different applications. 　　Proper installation and maintenance are also important for ensuring reliable performance from a metric oil seal. The seal should be installed correctly to ensure proper contact between the sealing element and the shaft. Regular maintenance, including lubrication and inspection for wear or damage, can help to extend the life of the seal. 　　Metric oil seal is a type of seal used to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes.

　　Oil seals, also known as shaft seals, are radial lip type seals that are primarily used for retaining lubricants in equipment having rotating, reciprocating or oscillating shafts. The rotating shaft application is most common. An oil seal normally consists of three basic components: the sealing element, the metal case, and the spring. 　　Oil seals are designed to prevent dirt, dust, water, or any other foreign matter from contaminating shafts and bearings in the rotary shaft equipment. They also block the leakage of lubricants such as grease and oil along a rotating shaft. 　　The most common types of oil seals are rubber-cased and metal-cased. Metal- cased oil seals are usually installed in a housing bore made of the same material. This allows for equal expansion and contraction of the materials during operation, preventing leakage. Rubber-cased oil seals are used under conditions where a metal-cased seal can fail (for example, because of thermal expansion). Unlike the metal-cased type, these seals do not rust. 　　Dust and debris are common reasons for oil seal failure. Entry of dust and debris is one of the most common reasons oil seals fail. For instance, in high- pressure applications, even the smallest sediments can create a gap in the seal, causing the oil to leak and dirt to get in. An effective way to ensure particles do not contaminate your oil seal is to store it in a container or sealed bag away from areas where dust and debris are prevalent. 　　Oil seals play an important role in preventing leaks and contamination in car engines. Understanding their basic components, types, and common causes of failure can help you maintain your car’s performance and prevent leaks.

　　A rubber oil seal is a sealing device that prevents liquids or gases from leaking out of mechanical equipment. It is usually installed between a rotating shaft and a stationary part. A rubber oil seal consists of an outer case, a rubber sealing lip, and a spring that preloads the lip against the shaft. 　　The temperature range that a rubber oil seal can withstand depends on the type and performance of the rubber material used in the seal. Rubber, like most other materials, has a temperature range in which it works the best. If the temperature exceeds this range, the rubber will lose its elasticity and flexibility, and the seal will no longer be able to fulfill its intended purpose. 　　Different types of rubber have different temperature ranges, depending on their chemical composition and properties. For example, according to some sources: 　　1. Natural rubber has a low temperature usage of -20° to -60° F (-29° to -51°C) and a high temperature usage of up to 175° F (80°C). 　　2. Nitrile rubber (NBR) has a low temperature usage of -40° to -10° F (-40° to -23°C) and a high temperature usage of up to 250° F (121°C). 　　3. Silicone rubber has a low temperature usage of -75° to -100° F (-59° to -73°C) and a high temperature usage of up to 450° F (232°C). 　　4. Fluorocarbon rubber (FKM) has a low temperature usage of -15° to 5° F (-26° to -15°C) and a high temperature usage of up to 400° F (204°C). 　　These are general guidelines, and the actual temperature range for a specific rubber oil seal may vary depending on the application and operating conditions. Factors such as pressure, speed, lubrication, fluid compatibility, and seal design can also affect the performance and durability of the seal at different temperatures. 　　Therefore, when selecting a rubber oil seal for an application, it is important to consider the expected temperature range and choose a suitable rubber material that can withstand it. By doing so, you can ensure that your rubber oil seal works efficiently and reliably for a long time.
