Oil seals, often known as rotary shaft seals, serve a pivotal role in safeguarding mechanical systems. These seals are expertly designed to prevent the escape of lubricants and the intrusion of contaminants like dirt and liquid, ensuring seamless operation of your equipment. The oil seal is an indispensable element in the architecture of any rotating and moving assembly, ensuring that the delicate balance between stationary and moving components in mechanical gear is maintained. Typically, an oil seal is composed of three essential elements:
A robust sealing material (rubber component), durable metal casings, and resilient springs. Together, these elements form a highly adaptable and efficient sealing assembly.
Our product range includes a wide array of types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and beyond, catering to diverse applications and needs.
Our expansive selection of rubber materials for oil seal manufacturing guarantees optimal performance across various operational settings. These advanced rubber materials are engineered to withstand a broad spectrum of chemicals and endure extreme temperatures, whether soaring high or plummeting low.
[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 |
