Oil seals, also known as rotary shaft seals, play a crucial role in maintaining the integrity of mechanical systems. These indispensable components are expertly designed to safeguard grease, liquids, or dirt, ensuring optimal functionality and longevity of machinery. By precisely stabilizing the interface between stationary and moving parts, oil seals are vital for any rotating assembly. They are expertly crafted with three primary elements:
A high-quality sealing material (rubber component), robust metal casings, and durable springs combine to create a versatile and reliable sealing assembly that stands up to demanding conditions.
Our diverse lineup includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4 models, among many others, catering to a wide array of needs.
We proudly offer an extensive range of premium rubber materials specifically engineered for oil seals, each selected to meet the rigorous demands of varied operating environments. These high-performance materials exhibit exceptional resilience, withstanding exposure to a broad spectrum of chemicals and extreme temperatures, both high and low.
[Oil seal material introduction]
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 |
