Oil seals, also known as rotary shaft seals, play a pivotal role in safeguarding machinery by effectively sealing in grease, liquids, or preventing dirt infiltration. These indispensable components are crucial for any rotating or moving assembly, as they expertly maintain the vital separation between stationary and dynamic parts within mechanical equipment. At the heart of a typical oil seal are three essential elements that ensure its optimal performance:
1. A high-quality sealing material composed predominantly of robust rubber components, providing exceptional flexibility and resilience. 2. Durable metal casings that offer structural integrity and dependable support. 3. Precision-engineered springs that deliver consistent pressure and enhanced sealing capability. This versatile sealing assembly is engineered to meet diverse needs.
Our extensive range of oil seal types includes TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each designed for specific applications and environments to ensure maximum efficiency.
We provide an extensive array of high-quality rubber materials tailored for oil seal manufacturing, each carefully selected to suit a wide array of operating conditions. Our premium rubber materials are engineered to resist a diverse spectrum of chemicals and endure extreme temperature fluctuations, whether in high-heat or frigid environments, ensuring longevity and reliability.
[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 |
