Oil seals, often known as rotary shaft seals, are integral to safeguarding mechanical systems. These indispensable devices effectively seal grease, liquids, and block dirt, serving as the guardian of any assembly that sees rotation and movement. They play a vital role in stabilizing the delicate balance between stationary and dynamic components within mechanical equipment. A typical oil seal is ingeniously crafted, comprising three essential elements that work in harmony:
A sophisticated sealing material made of rubber, robust metal casings, and resilient springs. This trio forms a remarkably versatile sealing assembly, tailored to meet diverse application needs.
Our range of oil seals expands to include several types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, ensuring a perfect fit for every requirement.
We offer a broad spectrum of rubber materials, meticulously selected for manufacturing oil seals. This ensures they are impeccably suited to a wide array of operating conditions. These high-performance materials are engineered to withstand a variety of challenging environments, from chemical exposure to extreme temperature variations, whether soaring high or plummeting low.
[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 |
