Oil seals, often recognized as rotary shaft seals, play a crucial role in protecting mechanical assemblies. These indispensable components effectively seal grease, liquids, or dirt, ensuring the optimal performance and longevity of rotating and moving systems. By stabilizing the space between stationary and moving parts, oil seals enhance the efficiency and reliability of mechanical equipment. Typically, an oil seal is crafted from three fundamental elements:
A reliable sealing material (usually a high-quality rubber component), robust metal casings, and durable springs. This combination creates a highly adaptable and versatile sealing assembly, suitable for a broad range of applications.
Types of oil seals we provide include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among a variety of other configurations to meet your specific needs.
We offer an extensive range of premium rubber materials, each carefully selected to ensure the manufacture of oil seals that excel under diverse operating conditions. These advanced materials withstand harsh chemicals and endure extreme temperatures, maintaining integrity in both high and low heat environments.
[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 |
