Oil seals, commonly known as rotary shaft seals, play an indispensable role in the efficient operation of mechanical assemblies. These vital components are expertly designed to prevent the ingress of grease, liquids, or contaminants, ensuring the seamless interaction of stationary and moving elements. As a pivotal part of any rotating and moving mechanism, they effectively stabilize and protect the integrity of your equipment. Constructed with precision, a typical oil seal comprises three integral constituents:
A meticulously engineered sealing material (rubber component), robust metal casings, and resilient springs. Together, they create a highly adaptable sealing assembly, ready to meet diverse industrial demands.
Our range includes various types: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the versatile TC4, to name a few.
We pride ourselves on offering an extensive array of premium rubber materials, each selected to craft oil seals capable of withstanding the most challenging operating environments. These exceptional materials are designed to resist a wide spectrum of chemicals and endure extreme temperatures, ensuring reliability in both high and low thermal conditions.
[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 |
