Oil seals, also popularly known as rotary shaft seals, serve as vital components in safeguarding machinery by effectively sealing in grease, fluids, or deterring dirt, thereby significantly extending the life of mechanical systems. These indispensable components are like the watchful protectors of mechanical assemblies, expertly maintaining the critical balance between stationary and moving parts. The quintessential construction of an oil seal involves three pivotal components:
An expertly crafted sealing material made from premium-grade rubber, fortified metal casings, and resilient springs. This harmonious blend results in a highly adaptable sealing assembly, proficient in enduring a myriad of operational challenges.
Our assortment of oil seals spans a comprehensive array of types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, offering bespoke solutions for a wide spectrum of applications.
We take immense pride in delivering an unrivaled selection of high-caliber rubber materials, meticulously engineered for manufacturing oil seals. These materials are chosen with precision to cater to an extensive range of operating conditions, demonstrating superior resilience against a variety of chemicals and extreme temperature fluctuations, ensuring optimal performance at all times.
[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 |
For optimal installation, it is crucial to thoughtfully consider the shaft's rotational speed, ambient temperature, applied pressure, and the characteristics of the medium. It's essential to ensure the vertical shaft is correctly aligned to prevent tilting and apply grease to the lip to reduce the risk of dry friction, thereby extending the seal's longevity.
