Oil seals, also known as rotary shaft seals, are indispensable components in the world of mechanical equipment. Their primary role is to effectively seal grease, liquids, or dirt, ensuring optimal operation of moving assemblies. By bridging the gap between stationary and moving parts, oil seals play a pivotal role in the stable functioning of mechanical systems. Typically, these seals are meticulously designed with three core elements:
A sealing material (the robust rubber component), sturdy metal casings, and resilient springs. This combination creates a versatile and reliable sealing assembly that adapts to diverse applications.
Our product range includes a variety of types: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others, catering to specific needs and preferences.
We proudly offer an extensive array of rubber materials tailored for oil seal production. Each material is crafted to withstand various operating conditions, showcasing exceptional endurance against a wide spectrum of chemicals and temperature extremes, from scorching highs to chilling lows.
[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 |
