Oil seals, also known as rotary shaft seals, play a pivotal role in maintaining the integrity of mechanical systems by effectively sealing grease, liquids, or dirt. An indispensable part of any rotating and moving machinery, the oil seal ensures a stable boundary between stationary and moving components, safeguarding the internal workings of equipment. Comprised of three core elements, this component is foundational to optimal equipment performance:
A sealing material (rubber component), metal casings, and resilient springs. This versatile assembly excels in providing reliable sealing solutions across diverse applications.
Our range includes various types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, ensuring comprehensive coverage for all sealing needs.
We proudly offer an extensive selection of premium rubber materials designed for oil seal production, guaranteeing compatibility with a vast array of operational environments. These advanced rubber compounds are engineered to withstand an extensive spectrum of chemicals and both high and low extreme temperatures, providing enduring performance and reliability.
[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 |
