Oil seals, often known as rotary shaft seals, play a crucial role in machinery by effectively sealing off grease, liquids, and dirt. These indispensable components stabilize the gap between stationary and moving elements within mechanical systems. A typical oil seal comprises three primary components that ensure its superior performance:
It includes a sealing material, which is a rubber component, along with robust metal casings and durable springs. This combination makes it an exceptionally versatile sealing assembly, adaptable to a variety of applications.
The types available include a wide range: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, to name a few, each designed to meet specific sealing requirements.
Our extensive selection of rubber materials for oil seals ensures compatibility with diverse operating conditions. These high-performance materials are engineered to withstand exposure to a spectrum of chemicals and endure extreme temperatures, both hot and cold, ensuring reliable performance.
[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, consider the shaft's rotation speed, temperature range, pressure levels, and medium characteristics for optimal performance. Ensure the shaft is mounted vertically to prevent any tilting, and apply grease to the lip to minimize the risk of dry grinding.
