Oil seals, also known as rotary shaft seals, are indispensable components that play a critical role in safeguarding mechanical assemblies. Designed to effectively seal grease, liquids, or dirt, these versatile seals are vital for maintaining the integrity of rotating and moving machinery parts. Their primary function is to stabilize the space between stationary and moving components, ensuring smooth, efficient operation across a wide array of industrial applications. Typically, an oil seal is ingeniously crafted from three essential elements:
A sealing material, often a robust rubber component, paired with strong metal casings and resilient springs. This combination forms a highly adaptable and effective sealing assembly, expertly engineered to meet diverse industrial demands.
Our range includes several types: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each tailored to specific sealing needs and applications.
We proudly offer an extensive variety of rubber materials tailored for the manufacturing of oil seals, each chosen to ensure optimal performance across varied operating conditions. Our high-performance rubber options are meticulously selected to withstand a broad spectrum of chemicals and extreme temperatures, both high and low, ensuring reliability and durability.
[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 |
