Oil seals, also revered in industry circles as rotary shaft seals, are indispensable for maintaining a pristine and effective seal against grease, liquids, or intrusive dirt. These oil seals are cornerstone components in the world of rotating and moving assemblies, expertly designed to stabilize and harmonize the space between stationary and moving parts within mechanical equipment. Typically, an oil seal is ingeniously crafted from three core elements:
a robust sealing material (rubber component), durable metal casings, and precision springs. This versatile and reliable assembly ensures peak performance across diverse applications.
Our product range includes an extensive variety of types: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the advanced TC4, among many others.
We proudly offer an expansive selection of premium rubber materials for the manufacturing of our oil seals, tailored to meet the unique demands of various operating conditions. These high-performance materials are engineered to withstand a broad spectrum of chemicals and endure extreme temperatures, both high and low, 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 |
