Oil seals, often known as rotary shaft seals, play a crucial role in sealing grease, liquids, or dirt, thereby protecting and ensuring the longevity of machinery. These indispensably robust components act as the guardians of mechanical equipment, adeptly stabilizing the vital spaces between stationary and moving parts. The typical composition of an oil seal includes three essential elements:
A sealing material crafted from high-quality rubber, robust metal casings, and durable springs. This perfect synergy creates a versatile sealing assembly, capable of withstanding various operational demands.
Our oil seal offerings encompass a wide variety of types, such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, providing tailored solutions for diverse applications.
We pride ourselves on providing an unparalleled selection of top-tier rubber materials engineered for the production of oil seals. These materials are meticulously chosen to suit a broad spectrum of operating conditions, exhibiting exceptional resilience against diverse chemicals and extreme temperature ranges, ensuring peak performance at all times.
[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 |
For optimal installation, it is vital to meticulously consider the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure the vertical shaft is installed correctly to avoid tilting, and apply grease to the lip to minimize any risk of dry grinding, prolonging the seal's life.
