Oil seals, also known as rotary shaft seals, play a critical role in maintaining the integrity of machinery. They expertly prevent the infiltration of grease, liquids, and dirt. As a vital component in any rotating and moving mechanism, the oil seal ensures flawless operation by stabilizing the interface between stationary and moving parts. The fundamental design of an oil seal encompasses three essential elements:
The sealing material, comprising a robust rubber component, is complemented by durable metal casings and resilient springs. Together, these elements form a highly adaptable sealing assembly.
Our product range includes a wide array of types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among many others, catering to diverse needs.
We pride ourselves on offering an extensive selection of premium rubber materials for oil seal production. Each material is meticulously chosen to meet varied operating conditions, providing exceptional resistance to a spectrum of chemicals and withstanding both high and low extreme temperatures.
[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 |
