Oil seals, often referred to as rotary shaft seals, play a pivotal role in preventing the escape of grease, liquids, or the intrusion of dirt, making them indispensable in any rotating and moving assembly. These seals are critical for maintaining the integrity of mechanical equipment by stabilizing the space between stationary and moving components. An oil seal typically comprises three core elements:
The sealing material, usually a robust rubber component, metal casings, and springs, which together form a highly adaptable sealing assembly.
Our product lineup includes a variety of types: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, to meet a wide range of sealing needs.
We provide an extensive array of rubber materials for manufacturing oil seals, ensuring they meet diverse operational demands. These high-performance materials are engineered to withstand an array of chemicals and endure extreme temperatures, whether soaring hot or freezing cold.
[Introduction to 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 |
