Oil seals, often known as rotary shaft seals, play a crucial role in sealing applications by preventing the escape of grease, liquids, or the intrusion of dirt. As a vital component in any dynamic and rotating assembly, the oil seal maintains harmony between the stationary and moving segments of mechanical equipment. It typically comprises three essential elements:
A sophisticated combination of a sealing material (rubber component), robust metal casings, and resilient springs. This versatile sealing assembly is designed for optimal performance across various applications.
Our comprehensive range of types includes TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among many others, to suit diverse needs.
We boast an extensive selection of premium rubber materials for our oil seals, tailored to meet the demands of varying operating conditions. These high-performance rubbers are engineered to withstand a broad spectrum of chemicals and handle extreme temperature variations with ease.
[Introduction to Oil Seal Materials]
| 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 |
