Oil seals, also known as rotary shaft seals, are indispensable in many machinery applications, expertly designed to effectively seal grease, liquids, or dirt. These vital components are crucial in maintaining the integrity of any assembly where stationary and moving parts interact, safeguarding the mechanical performance by stabilizing the space between these parts. Typically, an oil seal is composed of three essential elements:
A sealing material (the rubber component), metal casings, and springs, forming a versatile and integral sealing assembly.
Available types include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to a wide array of applications.
We provide a comprehensive array of superior rubber materials for oil seal manufacturing, meticulously ensuring their suitability for a vast range of operating conditions. Our high-performance rubber compositions are engineered to withstand a diverse spectrum of chemicals and excel in enduring extreme temperatures, whether intensely hot or freezing cold.
[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 |
