Oil seals, often known as rotary shaft seals, serve a crucial role in safeguarding mechanical equipment. Specifically designed to seal out grease, liquids, or unwanted dirt, these seals are fundamental to maintaining the integrity of any rotating or moving assembly. By effectively stabilizing the space between stationary and dynamic components, oil seals enhance the longevity and performance of mechanical parts. Consisting of three core elements, oil seals are indispensable in various industrial applications.
Each oil seal assembly is ingeniously crafted with a sealing material, comprised primarily of a robust rubber component, along with metal casings and resilient springs. This versatile sealing assembly provides an unmatched barrier against leaks and contaminations.
Our extensive range of oil seal types includes TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the advanced TC4, amongst others. Each variant is designed to cater to specific sealing needs.
We take pride in offering a wide array of meticulously selected rubber materials for oil seal manufacturing. These premium materials are engineered to meet diverse operational requirements, displaying remarkable resilience against various chemicals and withstanding extreme temperature fluctuations, from scorching highs to icy 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 |
