Oil seals, often recognized as rotary shaft seals, play a pivotal role in securing systems against grease, liquids, and dirt intrusion. As a vital component in any rotating and moving mechanical assembly, these seals maintain equilibrium by fortifying the space between static and dynamic parts within mechanical equipment. A typical oil seal is composed of three primary elements:
A sealing material (rubber component), robust metal casings, and resilient springs. This combination forms a versatile sealing assembly designed to meet the demands of various applications.
Our product range includes diverse types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each tailored for specific needs.
We proudly offer a comprehensive assortment of rubber materials for the production of oil seals, each selected for its ability to perform under diverse operational conditions. These high-quality rubber materials withstand a multitude of chemicals and endure extreme temperatures, whether soaring or freezing.
[Introducing Our Premium Oil Seal Materials]
| 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 |
