Oil seals, alternatively known as rotary shaft seals, play a crucial role in safeguarding machinery by effectively sealing grease, liquids, or contaminants. These indispensable components of any rotating or moving assembly bridge the gap between stationary and dynamic parts within mechanical equipment, ensuring seamless operation. An oil seal typically encompasses three fundamental elements:
A robust sealing material, often a rubber component, is complemented by durable metal casings and supportive springs, creating a highly adaptable sealing assembly.
Our extensive range includes various types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, amongst others, catering to diverse sealing needs.
We present an extensive array of premium rubber materials tailored for manufacturing oil seals, meticulously chosen to meet the demands of different operating environments. These materials exhibit exceptional resilience against a broad spectrum of chemicals and withstand extreme high and low temperatures with ease.
[Introducing the Exquisite 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 |
