Oil seals, also known as rotary shaft seals, play a pivotal role in safeguarding your machinery by effectively sealing grease, liquids, and preventing dirt ingress. These indispensable components are vital for any rotating or moving assembly, maintaining harmony between stationary and dynamic parts within mechanical equipment. The typical oil seal design ingeniously integrates three crucial elements:
A sophisticated sealing material (rubber component), robust metal casings, and resilient springs. This trio forms a versatile sealing assembly, aptly suited for diverse applications.
Our range includes various types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the advanced TC4 model, among others.
We proudly offer an extensive selection of rubber materials tailored for crafting oil seals that are precisely adapted for varied operational scenarios. These top-tier rubber materials boast resilience against an array of chemicals and withstand extreme temperature conditions, whether scorching high or freezing low, ensuring reliability and durability.
[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 |
