Oil seals, often known as rotary shaft seals, play a pivotal role in mechanical systems. These engineering marvels are indispensable for effectively sealing grease, liquids, or preventing dirt intrusion, safeguarding the integrity and performance of complex machinery. By forming a protective barrier between stationary and moving parts, they ensure the smooth operation of any rotating assembly. A standard oil seal is ingeniously crafted from three core elements:
A durable sealing material, typically rubber, robust metal casings, and resilient springs. This versatile combination makes it an exemplary sealing assembly, capable of meeting diverse industrial needs.
Our extensive range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others, each designed to cater to specific applications and requirements.
We proudly offer an impressive array of rubber materials tailored for oil seal manufacture, ensuring they meet a variety of operational demands. These superior rubber compounds are engineered to withstand an extensive range of chemical exposures and temperature extremes, whether high or low, thus guaranteeing unmatched durability and performance.
[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 |
