Oil seals, also known as rotary shaft seals, are pivotal in ensuring the seamless operation of mechanical systems. These indispensable components are designed to prevent the ingress of grease, liquids, or dirt, providing a robust barrier that fortifies the space between stationary and moving parts. Without oil seals, the heart of any rotating or moving assembly would be vulnerable to inefficiency and damage. The composition of an oil seal is elegantly simple yet masterfully effective, comprising three vital elements:
These integral components include a sealing material (the resilient rubber component), a durable metal casing, and a dependable spring. Together, they form a versatile sealing assembly that stands as a guardian against environmental challenges.
Our range of oil seal types extends to encompass diverse configurations such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, to name a few. Each type is engineered for specific applications and demands.
With an impressive selection of rubber materials at your disposal, our oil seals are crafted to meet and exceed the demands of various operational environments. These high-performance materials are specially formulated to withstand aggressive chemicals and withstand the extremes of heat and cold, proving reliability in the harshest 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 |
