What is an oil seal?
Also known as radial lip or rotary shaft seals, oil seals are used to retain or separate lubricants or fluids. Primarily used for rotary applications, these seals have a flexible lip that rubs against a shaft or housing. Oil seals perform two main functions: a) to maintain lubrication oils in place and; b) prevent the intrusion of dirt and other outside contaminants. Common configurations include single lip, double lip, with or without a spring, and metal or rubber covered.
Rubber Oil seal/ Machinery Seal main material :
Material | Temperature( ℃ ) | Advantage |
NBR | -40~+125 | Excellent abrasion resistance, Mineral oil resistant. |
SIR | -60~+225 | Excellent heat resistance, cold resistance and weatherability. |
FKM | -20~+250 | Have good heat resistance, oil resistant and chemicals resistance. |
EPDM | -40~+125 | Water resistance, resistance to polarity, solvent resistance, inorganic drug resistance, and good weatherability. |
SBR | Resistance to polarity, solvent resistance, Excellent resistance to water | |
PTFE | -45~+100 | Heat resistance, Excellent cold resistance, chemicals resistance, goodweatherability, Low friction coefficient of oil seal materials |
