Oil seals, also known as rotary shaft seals, play a pivotal role in the realm of mechanical equipment. They expertly safeguard crucial components by sealing in grease, liquids, and blocking dirt, ensuring the efficient operation of machinery. These indispensable components form the backbone of any rotating or moving assembly by maintaining a perfect balance between stationary and moving parts.
Typically crafted with precision, each oil seal embodies three core elements: a resilient sealing material (the rubber component), robust metal casings, and enduring springs. This ingenious combination creates a versatile sealing assembly, ready to meet diverse industrial needs.
Our product line boasts an array of types: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among various others, ensuring we cater to every conceivable requirement.
We pride ourselves on offering an extensive selection of premium rubber materials, meticulously chosen for the crafting of oil seals. Each material is tailored to withstand a spectrum of operational conditions. From the extremities of high heat to the challenges of low temperatures, our high-performance materials resist a myriad of chemicals, assuring reliability and durability.
[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 |
