Oil seals, also known as rotary shaft seals, play a pivotal role in safeguarding mechanical systems by effectively sealing grease, liquids, or dirt. These indispensable components are vital for the smooth operation of any assembly with rotating or moving parts, ensuring stability and efficiency between stationary and dynamic components. An oil seal is ingeniously crafted with three core elements:
A sealing material (the robust rubber component), durable metal casings, and precision-engineered springs. This versatile sealing assembly is designed to meet a variety of needs.
The diverse types include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and more. Each type is meticulously engineered for optimal performance in specific applications.
We proudly offer an extensive range of premium rubber materials for crafting oil seals, perfectly tailored for diverse operating environments. These top-tier materials boast exceptional resilience against a myriad of chemicals and withstand extreme temperature conditions, from soaring 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 |
