Oil seals, also known as rotary shaft seals, are vital in protecting mechanical assemblies by effectively sealing against grease, liquids, or dirt. They play a crucial role in stabilizing the space between stationary and moving parts within mechanical equipment. Typically composed of three essential elements, oil seals are indispensable in ensuring the smooth operation of any rotating or moving assembly.
These three essential elements include a durable sealing material (rubber component), robust metal casings, and reliable springs, making it a versatile and efficient sealing assembly to meet various sealing requirements.
Our product range includes various types of oil seals such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to a wide spectrum of industrial applications.
We proudly offer an extensive selection of premium rubber materials tailored for manufacturing oil seals, ensuring they are perfectly suited for diverse operating conditions. These high-performance materials are designed to withstand a broad range of chemicals and endure extreme temperatures, whether soaring high or freezing low.
[Introduction to Oil Seal Materials]
Ding Rubber (NBR) | Temperature resistance of 100ºC, good oil resistance, wear resistance, anti-aging, good sealing effect. |
silica gel (VMQ) | Temperature resistance of 200ºC, general oil resistance, high temperature resistance, good waterproof, non-toxic. |
Fluorogel (FKM) | Temperature resistance of 280ºC, good oil resistance, wear resistance, high pressure resistance, corrosion resistance. |
ethylene-propylene-diene misch-polymere (EPDM) | Temperature resistance of 150ºC, general oil resistance, corrosion resistance. |
(PTFE) | Temperature resistance of 280ºC, good oil resistance, wear resistance, high pressure and corrosion resistance. |
polyurethane (PU) | Temperature resistance of 90ºC, good oil resistance, wear resistance. |
Single lip structure | Single channel sealing lip for low pressure reciprocating motion (e. g. automotive crankshaft oil seal) |
Double lip structure | Two upper and lower sealing lips, a main seal (contact shaft), a secondary seal (dust), often used in high pressure environment |
Composite lip structure | Main lip + dust lip + buffer spring (like type NOK TCV), can withstand both radial and axial forces |
labyrinth packing | Multi-channel ring groove design to block oil by throttling effect (suitable for high-speed rotating axis) |
Seal the oil swing ring | Metal ring rotating centrifugal oil swing with shaft (commonly used in gearbox gearbox) |
Component name | Material selection | function declaration |
seal(ing)lip | NBR/FKM/PTFE | Main seal surface, the contact shaft forms a dynamic seal |
spring | Stainless steel / carbon steel | Provide lip pretension to compensate for wear |
skeleton | PA6/PC | Fixed the sealing lip shape and transfer the mounting stress |
Dust-proof lips | polyurethane elastomer | Blocking the entry of solid impurities (optional) |
Self-lubricating coating | plumbago/PTFE | Reduce the friction coefficient and extend the life life |
