Oil seals, also known as rotary shaft seals, serve a crucial role in safeguarding mechanical systems. Expertly designed to effectively seal grease, liquids, or prevent dirt infiltration, these seals are indispensable for any rotating or moving assembly. By maintaining stability between stationary and dynamic parts of mechanical equipment, oil seals ensure optimal performance and longevity. Typically, an oil seal is crafted with three vital components:
These components include a sealing material made from high-quality rubber, sturdy metal casings, and durable springs. This combination creates a versatile and reliable sealing assembly for various applications.
Our range of oil seal types is extensive, including: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among many others, catering to diverse industry needs.
We proudly offer an extensive array of premium rubber materials tailored for the production of oil seals. Each material is meticulously selected to ensure compatibility with diverse operating conditions. Our high-performance rubbers can withstand exposure to harsh chemicals and endure extreme temperature variations, whether scorching hot or freezing cold.
[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 |
