Product Description

Oil seals, often known as rotary shaft seals, serve a critical function in maintaining the integrity of your mechanical assemblies. Designed to effectively seal grease, liquids, or dirt, these indispensable components stabilize the gap between stationary and moving parts, ensuring optimal performance. Typically, an oil seal is composed of three primary components:
a sealing material, often a rubber component, reinforced with robust metal casings and springs. This combination results in a highly versatile sealing assembly, adept at accommodating diverse mechanical needs.
Explore our extensive range of oil seal types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others, tailored to meet your specific application requirements.
We pride ourselves on offering an extraordinary array of rubber materials for crafting oil seals, meticulously selected to withstand varying operating conditions. These top-tier materials are designed to resist an array of chemicals and endure extreme temperature fluctuations, both high and low, ensuring your equipment's reliability.

[Oil seal material introduction]

We provide the flexibility of customizable non-standard oil seals, expertly crafted from premium materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, to precisely match your unique specifications.

[Oil seal and sealing principle]

Our oil seals operate by forming an oil film through the intimate contact of the lip with the shaft. This dynamic sealing is achieved through the synergy of spring pressure and material elasticity. During rotation, friction-induced heat causes the lip to contract, enhancing the seal, while at rest, it maintains seal integrity through consistent contact.

[Oil seal application fields]

Our oil seals are indispensable across a wide array of applications, including engines, gearboxes, hydraulic pumps, and reducers. They excel in high-temperature, high-speed, and corrosive environments where traditional seals fail. Notably, PTFE oil seals offer an impressive lifespan, lasting up to 20 times longer than conventional seals, and can effectively seal water, acid, gas, and other challenging media.

[Oil seal selection and installation]

Consider the shaft's rotation speed, temperature, pressure, and medium characteristics thoroughly. Ensure vertical shaft installation to prevent misalignment and apply grease to the lip for minimizing dry grinding, ensuring prolonged seal life and efficiency.

[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.

[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
