Oil seals, often recognized as rotary shaft seals, are vital for safeguarding your machinery by effectively sealing grease, liquids, or dirt. These indispensable components are integral in maintaining the precise gap between stationary and dynamic parts within your mechanical equipment, ensuring optimal performance and longevity. Each oil seal is meticulously constructed from three core elements:
A robust sealing material (rubber component), sturdy metal casings, and resilient springs. This dynamic trio forms a versatile sealing assembly, engineered for reliability and durability.
Explore the versatility of our oil seals with types like: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, tailored for diverse applications.
Our diverse selection of rubber materials is crafted to meet the unique demands of oil seal manufacturing, ensuring compatibility across various operational environments. These high-performance rubbers are engineered to withstand an array of chemicals and endure extreme temperature fluctuations, whether soaring highs or freezing lows, providing unmatched durability and resilience.
[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 |
