Oil seals, also known as rotary shaft seals, play a pivotal role in machinery by effectively sealing grease, liquids, or dirt. These indispensable components are vital for any rotating and moving assembly, ensuring stability in the space between stationary and moving parts within mechanical equipment. Typically, an oil seal comprises three integral elements that work harmoniously:
A sealing material (specifically the rubber component), robust metal casings, and reliable springs. This versatile sealing assembly is designed to meet diverse application needs.
Our product range includes various types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, offering tailored solutions for every requirement.
We proudly offer an extensive selection of premium rubber materials for oil seal manufacturing, providing compatibility with a multitude of operating conditions. These high-performance materials are engineered to withstand challenging chemicals and withstand both intense heat and severe cold, ensuring peak functionality.
[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 |
When installing, take into account the rotation speed, temperature, pressure, and medium characteristics of the shaft comprehensively. Ensure the vertical shaft is correctly aligned to prevent tilting and apply grease to the lip generously to minimize dry grinding and extend the seal's lifespan.
