Oil seals, often known as rotary shaft seals, serve as the guardians of your machinery, expertly sealing in grease, liquids, and barring dirt from invading your critical mechanical assemblies. These indispensable components are the linchpins that harmonize the dynamic interaction between stationary and moving parts within diverse mechanical equipment. The quintessential oil seal is masterfully constructed from three pivotal elements:
A sophisticated sealing material (rubber component), robust metal casings, and flexible springs. This multifunctional sealing assembly is engineered for superior versatility.
Our offerings encompass a wide array of types including, but not limited to: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4.
We proudly present an extensive range of premium rubber materials meticulously chosen for crafting oil seals, tailored to meet the demands of various operational environments. These high-caliber materials are designed to withstand a spectrum of chemicals and endure extreme temperature variations, from soaring highs to frigid lows.
[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 |
