Product Description

Oil seals, also known as rotary shaft seals, play a crucial role in sealing grease, liquids, or dirt within mechanical systems. These indispensable components stabilize the interface between static and dynamic parts in any rotating or moving assembly. An oil seal generally comprises three key elements that work harmoniously to ensure optimal performance.
The fundamental elements of an oil seal include a sealing material (rubber component), robust metal casings, and springs, which together form a highly adaptable and versatile sealing assembly.
Explore our extensive range of oil seal types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among many others, to meet a variety of specific needs and applications.
Our diverse selection of premium rubber materials for oil seal manufacturing ensures compatibility with a wide spectrum of operating conditions. These high-performance rubber options are designed to withstand exposure to aggressive chemicals and endure extreme temperatures, both high and low.
[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.

We offer the ability to produce bespoke non-standard oil seals using advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet specific customer requirements.

[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 innovation of the oil seal lies in creating an oil film at the lip-to-shaft contact point, where dynamic sealing is achieved through the synergy of spring pressure and material elasticity. During rotation, the lip's contraction due to frictional heat augments the seal's effectiveness, while at rest, it maintains its position to ensure continued sealing integrity.

[Oil Seal Application Fields]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and more, particularly thriving in high-temperature, high-speed, and corrosive environments. Notably, PTFE oil seals offer a remarkable lifespan, lasting up to 20 times longer than standard versions and providing exceptional sealing for water, acid, gas, and various challenging media.

[Oil Seal Selection and Installation]
A comprehensive evaluation of the shaft's rotation speed, temperature, pressure, and medium characteristics is crucial for optimal oil seal selection and installation. Ensuring the vertical alignment of the shaft prevents tilting, while applying grease to the lip reduces the risk of dry grinding, enhancing longevity.
