Oil seals, also known as rotary shaft seals, are indispensable components in mechanical assemblies, adeptly designed to prevent the escape of grease and liquids or the infiltration of dirt. These seals play a crucial role in all rotating and moving assemblies by maintaining stability between stationary and moving parts, fostering optimal performance.
An oil seal is ingeniously crafted from three primary components: the resilient sealing material (rubber component), robust metal casings, and reliable springs, forming a versatile sealing assembly that adapts to various applications and conditions.
Our product range includes a variety of types: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, amongst others, each designed to meet specific operational needs.
We pride ourselves on offering a wide array of premium rubber materials for oil seal production, tailored to ensure superior performance across diverse operating conditions. These high-caliber materials are engineered to withstand an array of chemicals and endure extreme temperature fluctuations, both high and low, assuring reliability and longevity in demanding applications.
[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 |
