Oil seals, also known as rotary shaft seals, serve as vital protective barriers that guard against the intrusion of grease, liquids, or dirt. These indispensable components play a critical role in the functionality of any rotating and moving assembly. They expertly maintain the balance and stabilize the gap between stationary and moving parts within mechanical equipment. Typically, an oil seal is crafted with three key elements:
These essential elements include a resilient sealing material (rubber component), robust metal casings, and durable springs. This configuration creates a highly adaptable sealing assembly that meets diverse requirements.
Our comprehensive range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, to cater to a wide spectrum of applications.
We proudly offer a vast array of superior rubber materials for the production of oil seals, ensuring that they are perfectly suited for a multitude of operating conditions. These high-performance materials are engineered to withstand a broad range of chemicals and the most extreme temperature conditions, whether soaring heat or freezing cold.
[Introduction to Premium Oil Seal Materials]
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 |
