Product Description

Oil seals, often referred to as rotary shaft seals, are indispensable in maintaining the integrity of mechanical assemblies. These seals effectively prevent the intrusion of grease, liquids, or dirt, playing a crucial role in stabilizing the space between stationary and moving parts of mechanical equipment. An oil seal is typically comprised of three foundational components:
A resilient sealing material (rubber component), robust metal casings, and durable springs. This versatile sealing assembly ensures optimal performance under diverse conditions.
Our oil seal types include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and more, catering to a broad spectrum of requirements.
We offer an extensive array of premium rubber materials to craft our oil seals, designed to perform under various operational conditions. These high-performance materials endure aggressive chemicals and withstand extreme temperatures.
[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.

Customizable non-standard oil seals are available, crafted from advanced materials including fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet specific needs.

[Core Structures of Oil Seals]

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)

[Essential Structural Components of the Oil Seal]

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

[Principle of Oil Seal and Sealing Mechanism]
Oil seals function by generating an oil film at the contact point between the lip and shaft, achieving an effective dynamic seal through the synergy of spring pressure and material elasticity. During rotation, the lip contracts due to frictional heat, enhancing the sealing quality; it maintains contact when stationary to ensure a consistent seal.

[Applications of Oil Seals]
Our oil seals are extensively utilized in engines, gearboxes, hydraulic pumps, reducers, and other machinery. They excel in challenging environments like high temperatures, high speeds, or corrosive conditions where traditional seals may falter. Specialized PTFE oil seals boast a lifespan up to 20 times longer than conventional counterparts, effectively sealing water, acid, gas, and more.

[Oil Seal Selection and Installation Guidelines]
When selecting oil seals, consider shaft rotation speed, temperature, pressure, and medium characteristics comprehensively. Ensure vertical installation to prevent tilting and apply grease on the lip to minimize dry friction.
