Oil seals, also known as rotary shaft seals, perform the critical role of sealing grease, liquids, or dirt in mechanical assemblies. These indispensable components are pivotal for maintaining the integrity and operational efficiency of any rotating or moving machinery by stabilizing the space between stationary and dynamic parts. Generally, an oil seal comprises three essential elements:
A sealing material made from a superior rubber component, robust metal casings, and durable springs, forming an ingenious and adaptable sealing assembly.
Our extensive range of oil seal types includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to a wide array of industrial needs.
Embrace the versatility of our oil seals crafted from a diverse selection of high-grade rubber materials. These materials are meticulously chosen for their capacity to withstand various chemicals and endure extreme temperatures, both high and low, ensuring optimal performance under challenging operating 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 |
When installing, take a comprehensive approach by considering the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensuring proper vertical alignment of the shaft is optimal to prevent tilting, while applying grease to the lip is essential to minimize dry grinding and enhance longevity.
