Discover our range of oil seals, also known as rotary shaft seals, indispensable for sealing grease, liquids, and dirt in various applications. These oil seals play a critical role in any rotating or moving assembly, expertly stabilizing the space between stationary and mobile components within mechanical systems. A typical oil seal is ingeniously crafted from three core elements:
This sophisticated sealing assembly features a sealing material (rubber component), robust metal casings, and tension springs, ensuring versatility and reliability.
Explore our wide array of oil seal types including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among many others, designed to meet your unique needs.
Our extensive range of high-grade rubber materials for oil seal manufacturing promises unmatched performance, tailored for diverse operating conditions. These materials are engineered to withstand a broad spectrum of chemicals and endure extreme temperatures, providing optimal functionality in both high and low-temperature environments.
[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 |
