Oil seals, often known as rotary shaft seals, play a crucial role in maintaining the integrity of mechanical systems. Their primary function is to prevent the leakage of grease, liquids, or dirt, making them indispensable in any rotating or moving assembly. By efficiently stabilizing the space between stationary and moving components in machinery, oil seals ensure the smooth and reliable operation of equipment. An oil seal typically comprises three essential elements:
These components include a robust sealing material (rubber component), durable metal casings, and resilient springs, forming a versatile sealing assembly designed to meet a wide range of industrial needs.
Types available include an extensive range such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the advanced TC4, among others, catering to diverse application requirements.
We proudly offer an extensive selection of premium rubber materials for crafting oil seals, ensuring they are ideally suited for various operational conditions. These high-performance rubber materials possess exceptional resilience, capable of withstanding a broad spectrum of chemicals and enduring extreme temperatures, whether blisteringly high or freezing low, thereby guaranteeing optimal functionality and longevity.
[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 |
