Oil seals, often known as rotary shaft seals, play a vital role in safeguarding machinery by effectively sealing and preventing the ingress of grease, liquids, or dirt. These indispensable components ensure the integrity of any rotating or moving assembly by maintaining a stable gap between the stationary and dynamic parts of mechanical equipment. An oil seal is typically composed of three integral elements:
A resilient sealing material, typically a rubber component, metal casings, and springs. This combination forms a highly adaptable sealing assembly that caters to a wide range of applications.
Our extensive range of oil seal types includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among many others, ensuring that you will find the perfect fit for your specific sealing requirements.
We proudly offer a comprehensive array of premium rubber materials for crafting our oil seals, designed to perfectly match diverse operating conditions. These advanced rubber materials are engineered to withstand a broad spectrum of chemicals and extreme temperatures, both high and low, ensuring optimal performance across various demanding environments.
[Introduction to Oil Seal Materials]
| 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 |
