Oil seals, known for their vital role as rotary shaft seals, are indispensable in a myriad of applications where they effectively seal grease, prevent leakage of liquids, and block dirt intrusion. As a critical component in any rotating or moving assembly, oil seals are crucial for stabilizing and maintaining the delicate balance between stationary and dynamic parts within mechanical machinery. Typically, these seals are composed of three essential elements:
A meticulously crafted sealing material (rubber component), robust metal casings, and durable springs. Together, they form a versatile and reliable sealing assembly ready to meet the challenges of diverse industrial needs.
Our oil seal offerings include a comprehensive variety of types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, among many others, each designed to fulfill specific requirements.
We proudly present an extensive array of top-grade rubber materials engineered for the precise manufacturing of oil seals, ensuring their adaptability across a wide spectrum of operational conditions. These exceptional rubber materials are formulated to withstand the harshest chemical environments and extreme temperature fluctuations, ensuring peak performance even under the most demanding circumstances.
[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 |
