Oil seals, also known as rotary shaft seals, serve as vital components in mechanical systems by effectively sealing grease, liquids, or dirt. They are indispensable for maintaining the integrity of any rotating or moving assembly, ensuring a stable interface between stationary and dynamic parts within mechanical equipment. Every oil seal is ingeniously crafted from three core elements.
These elements include a robust sealing material, usually a rubber component, reinforced metal casings, and durable springs, forming a versatile sealing assembly designed to adapt to various applications.
Our comprehensive product range includes various types, such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each tailored to meet specific sealing needs.
We proudly offer a diverse array of premium rubber materials for manufacturing oil seals, ensuring they are perfectly suited to a wide range of operating conditions. These high-performance materials boast exceptional resilience, capable of withstanding a broad spectrum of chemicals and temperatures, whether scorching heat or freezing cold.
[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 |
