Oil seals, also elegantly known as rotary shaft seals, are pivotal in safeguarding mechanical harmony. These seals masterfully prevent the intrusion of grease, liquids, or dirt, ensuring the flawless operation of all systems. As the unsung heroes of any rotating and moving assembly, oil seals secure the delicate balance between stationary and moving components in mechanical equipment. Their sophisticated design typically comprises three vital elements:
A highly adaptable sealing material (rubber component), robust metal casings, and resilient springs. This assembly is renowned for its versatility and effectiveness in various applications.
Explore our extensive array of types, including: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, to meet diverse sealing needs.
Our curated selection of premium rubber materials for oil seal manufacturing is crafted to excel under an array of operating conditions. These advanced materials are engineered to withstand harsh chemicals and extreme temperature fluctuations, ensuring durability and reliability in every application.
[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 |
