Oil seals, commonly known in the industrial realm as rotary shaft seals, are a pivotal component in ensuring optimal functionality of machinery. These ingenious seals perform the critical task of securing grease, liquids, or dirt, acting as a guardian for the intricate mechanisms within your equipment. By stabilizing the space between stationary and moving parts, oil seals play a fundamental role in the performance and longevity of any rotating and moving assembly. An oil seal is typically comprised of three core elements:
A meticulously crafted sealing material (rubber component), robust metal casings, and resilient springs. This strategic combination forms a versatile sealing assembly that stands up to the demands of modern machinery.
Our oil seals come in a variety of types to suit your specific needs, including: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the advanced TC4, among others.
We proudly provide a diverse and comprehensive selection of rubber materials tailored specifically for manufacturing oil seals. This ensures compatibility with a multitude of operating conditions, providing high-performance solutions that withstand a wide range of chemicals and endure extreme temperatures, both high and low.
[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 |
