Product Description

Oil seals, often referred to as rotary shaft seals, are essential components in mechanical machinery, playing the pivotal role of sealing grease, liquids, or dirt to maintain the integrity and efficiency of rotating and moving assemblies. By stabilizing the gap between stationary and moving parts, these seals ensure uninterrupted and smooth operation of various mechanical equipment. Typically, these vital devices are composed of three fundamental elements:
A meticulously crafted assembly featuring durable sealing material (rubber component), sturdy metal casings, and resilient springs, making this ingenious design an incredibly versatile and reliable sealing solution.
Our comprehensive selection features types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and many others, meticulously designed to cater to a wide array of diverse and specific needs.
We offer an impressive array of high-quality rubber materials for constructing oil seals, each carefully selected to endure a wide variety of operating conditions. These exceptional materials provide outstanding chemical resistance and can withstand extreme temperatures, ensuring consistent performance and reliability despite environmental challenges.
[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.

Our tailor-made, non-standard oil seals are crafted from advanced materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring a precise and perfect fit for specific and specialized applications.

[Oil seal core structure type]

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)

[Key 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

[Oil seal and sealing principle]
The oil seal operates by creating an oil film as the lip makes contact with the shaft, achieving a dynamic seal through the application of spring pressure and the material's inherent elasticity. During rotation, the ensuing frictional heat causes the lip to contract, enhancing the seal, while in a stationary state, contact is maintained to ensure ongoing and unfaltering protection.

[Oil seal application fields]
Our high-performance oil seals are widely used in engines, gearboxes, hydraulic pumps, and reducers, especially in demanding scenarios involving high temperatures, rapid speed, or corrosive environments where traditional seals are inadequate. PTFE oil seals, in particular, exhibit a remarkable lifespan up to 20 times longer than ordinary seals, expertly sealing diverse media such as water, acid, and gas.

[Oil seal selection and installation]
When selecting and installing an oil seal, it's imperative to consider the holistic nature of the shaft's rotation speed, temperature, pressure, and medium characteristics. It's essential to mount the shaft vertically to prevent tilting and apply grease to the lip to minimize dry friction and extend the seal's lifespan.
