Oil seals, elegantly known as rotary shaft seals, are indispensable in sealing mechanisms, serving to effectively seal grease, liquids, or keep dirt at bay. These vital components are essential in any rotating and moving assembly, providing stabilization between stationary and moving parts in a wide array of mechanical equipment. An oil seal is ingeniously crafted from three critical elements:
A robust sealing material (the rubber component), solid metal casings, and resilient springs. Together, these elements form a highly adaptable sealing assembly, capable of meeting diverse needs.
Our product range includes various types, such as: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each designed to meet specific requirements and applications with precision.
We proudly offer an extensive array of premium rubber materials tailored for crafting oil seals, guaranteeing optimal performance across a variety of operating conditions. These exceptional materials withstand exposure to a broad spectrum of chemicals and endure extreme temperatures, both high and low, ensuring reliability and longevity.
[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 |
When installing, consider the comprehensive factors such as rotation speed, temperature, pressure, and the characteristics of the medium. Ensure vertical shaft installation to avoid tilting and apply grease to the lip to minimize dry grinding.
