Oil seals, frequently known as rotary shaft seals, serve as vital guardians in various assemblies, expertly sealing grease, liquids, and dirt. These indispensable components play a crucial role in any rotating or moving mechanism, meticulously maintaining the delicate balance between stationary and moving parts within mechanical equipment. Crafted with precision, an oil seal is composed of three key elements:
A robust sealing material (rubber component), sturdy metal casings, and resilient springs. This ingenious combination creates a versatile sealing assembly, designed to adapt to a multitude of scenarios.
Our collection boasts a variety of types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, offering a solution for every need.
We proudly offer an extensive array of rubber materials for crafting oil seals, ensuring that they are perfectly suited to a wide array of operating conditions. These high-performance rubber materials stand resilient against a spectrum of chemicals and withstand the extremities of temperature, be it scorching heat or freezing cold.
[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 |
