The following are the methods for selecting appropriate floating oil seal materials and applicable temperature ranges according to actual working conditions:

Considering Working Temperature

1. Low Temperature Environment:
   If the equipment often operates in a low temperature environment, such as some outdoor low temperature working conditions where the temperature is below 0°C or even drops to minus tens or dozens of degrees Celsius, materials with good low temperature resistance can be preferentially selected. For example, silicone rubber floating oil seals are a good choice. They can maintain good elasticity and sealing performance within a relatively wide low temperature range, usually adaptable to a temperature range from about -60°C to 200°C. At the low temperature end, they can effectively prevent the oil seals from becoming hard and brittle due to low temperature and losing their sealing effect.
2. Normal Temperature Environment:
   For equipment working in a general normal temperature environment (approximately from -30°C to 100°C), nitrile rubber (NBR) floating oil seals are a common choice. Its cost is relatively moderate, and it can stably play a sealing role within this temperature range, which is sufficient to meet the sealing requirements of most conventional working conditions, such as in ordinary industrial machinery and agricultural machinery.
3. High Temperature Environment:
   When the equipment is in a high temperature environment, like in the metallurgical and chemical industries where the temperature around some equipment may exceed 100°C or even be higher, fluoroelastomer (FKM) floating oil seals have more advantages. Fluoroelastomer can withstand relatively high temperatures, with an applicable temperature range of approximately from -20°C to 200°C. It can maintain good physical and chemical properties under high temperature conditions to ensure reliable sealing and prevent the oil seals from aging and deforming too quickly and failing.
