Oil seals, often called rotary shaft seals, are indispensable in preventing the leakage of grease, liquids, or intrusion of dirt, safeguarding the integrity of machinery. They are a critical component in numerous rotating and moving systems, seamlessly bridging stationary and dynamic parts. A typical oil seal is ingeniously crafted with three key elements:
The sealing material, usually a high-grade rubber component, complemented by robust metal casings and resilient springs, forms a versatile and reliable sealing assembly that ensures optimal performance.
Available in a variety of types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, these seals are designed to meet diverse application requirements.
We proudly offer an extensive range of specialized rubber materials tailored for oil seal production, each expertly engineered to thrive under various operational conditions. These premium materials withstand a spectrum of chemicals and extreme temperatures, ensuring durability and efficiency in both high and low thermal environments.
[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 |
