Oil seals, also known as rotary shaft seals, are crucial for maintaining the integrity of grease, liquids, and dirt within mechanical systems. These indispensable components form a critical interface, ensuring a seamless interaction between stationary and moving elements in mechanical equipment. Each oil seal is ingeniously crafted with three pivotal components:
The trifecta of an oil seal includes a sealing material (rubber component), robust metal casings, and resilient springs, forming an adaptable sealing assembly capable of withstanding various mechanical demands.
Our selection features a wide array of types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to diverse sealing needs.
We proudly present an extensive range of rubber materials meticulously chosen for oil seal production, tailored to meet the rigorous demands of varied operational environments. These exceptional materials boast resilience against a spectrum of chemicals and extreme temperature conditions, ensuring reliability and efficiency.
[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 |
Installation must consider factors like rotation speed, temperature, pressure, and medium characteristics. Ensure the vertical shaft is correctly installed to prevent tilting. Apply grease to the lip to minimize dry grinding and enhance the longevity of the seal.
