Oil seals, also illustriously known as rotary shaft seals, serve a crucial function in the realm of mechanical engineering. They are adeptly used to seal grease, liquids, or dirt, ensuring the longevity and efficiency of various applications. Oil seals play a vital role in any apparatus that involves rotating and moving assemblies, harmonizing the interface between stationary and moving parts in mechanical equipment. An oil seal is typically constructed from three essential components:
A robust sealing material, typically a high-grade rubber component, fortified metal casings, and resilient springs. This composition forms a versatile sealing assembly, adept at maintaining optimal performance under diverse conditions.
Explore our extensive range of oil seal types, which includes but is not limited to: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the advanced TC4 types, among others.
We proudly offer an impressive array of rubber materials tailored for the meticulous manufacturing of oil seals. These materials are designed to meet the demands of various operating conditions, showcasing exceptional durability against a multitude of chemicals and withstanding extreme temperatures, whether scorching or freezing.
[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 |
