Oil seals, also known as rotary shaft seals, are indispensable components that expertly seal grease, liquids, and even dirt. These seals play a crucial role in maintaining the integrity of any rotating and moving assembly by providing a stable partition between stationary and dynamic parts within mechanical equipment. The quintessential oil seal is crafted from three essential elements:
A robust sealing material (rubber component), durable metal casings, and resilient springs form the versatile sealing assembly, delivering reliable performance under various conditions.
Our product line includes a comprehensive array of types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, to cater to diverse needs.
We proudly offer an extensive selection of premium rubber materials tailored to the manufacturing of oil seals. These materials are engineered to withstand a wide spectrum of chemicals and tolerate extreme temperature variations, ensuring optimal performance across different operating 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 |
When installing, consider the shaft's rotational speed, temperature, pressure, and medium characteristics to optimize performance. Ensure vertical alignment to prevent tilting and generously apply grease to the lip for reduced dry grinding and enhanced longevity.
