Oil seals, often recognized as rotary shaft seals, play a crucial role in safeguarding and enhancing the performance of mechanical assemblies. They are indispensable in sealing grease, liquids, and dirt, thereby ensuring the longevity and efficiency of various devices. This vital component stabilizes and protects the interface between stationary and moving parts, forming a seal that is critical to the smooth operation of mechanical equipment. Generally, an oil seal is composed of three primary elements:
A robust sealing material, typically a rubber component, accompanied by durable metal casings and flexible springs, form a highly adaptable sealing assembly that meets diverse application needs.
Explore our diverse range of oil seal types including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each engineered for specific applications.
Our broad selection of premium rubber materials for oil seal manufacturing guarantees compatibility with a variety of operational environments. These advanced rubber compounds are engineered to withstand a broad spectrum of chemicals and endure extreme temperatures, ensuring reliability under the most demanding conditions.
[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 |
