Oil seals, often known as rotary shaft seals, are indispensable components within numerous industrial applications. These versatile seals primarily serve to prevent the escape of lubricants, and to block unwanted contaminants such as dirt and liquids. Integral to the functionality of any rotating or reciprocating machinery, the oil seal ensures seamless operation by maintaining a protective barrier between stationary and dynamic components in mechanical systems. The construction of an oil seal traditionally involves three key elements:
A sealing material composed of high-quality rubber, durable metal casings, and resilient springs. This trio forms a robust and adaptable sealing mechanism.
Our extensive range of oil seals encompasses various types: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the specialized TC4, among others, each crafted to meet specific application needs.
We proudly present an expansive variety of premium rubber materials in our oil seal production, meticulously designed to excel in diverse operational environments. These high-performance materials boast remarkable resilience against a vast array of chemicals and withstand both the extremities of soaring and plunging temperatures with unwavering effectiveness.
[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 |
