Product Description

Oil seals, also known as rotary shaft seals, play a crucial role in machinery by effectively sealing in grease, liquids, or preventing dirt intrusion to guarantee seamless operations. These essential components stabilize the interface between stationary and moving parts within mechanical equipment, ensuring reliability and efficiency. Typically, an oil seal comprises three integral elements:
The sealing assembly is an engineering marvel, featuring a combination of sealing material (rubber component), metal casings, and springs. This versatile design epitomizes durability and reliability, offering unmatched performance.
Delve into our expansive range of types including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the revolutionary TC4, among others, designed to meet diverse sealing requirements.
Our selection of high-performance rubber materials for oil seals is unparalleled, expertly designed to resist a multitude of chemicals and endure extreme temperatures. They are meticulously engineered to operate under varying conditions, whether facing intense heat or freezing cold, maintaining optimal performance.
[Introduction to oil seal material]

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.

For unique requirements, we offer customizable non-standard oil seals, crafted from specialized materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring tailored solutions to specific challenges.

[Types of oil seal core structures]

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 seals and sealing]
The oil seal functions on an advanced principle, forming an oil film through dynamic interaction between the lip and the shaft. Utilizing spring pressure and the intrinsic elasticity of the materials, it ensures a durable seal. During operation, frictional heat causes the lip to contract, bolstering the seal, while at rest, it maintains its grip, preserving integrity.

[Fields of application for oil seals]
Our oil seals are vital in engines, gearboxes, hydraulic pumps, reducers, and beyond. They excel in extreme environments characterized by high temperatures, high speeds, and corrosive conditions, where conventional seals may falter. For instance, our PTFE oil seals offer longevity up to 20 times greater than traditional seals, effectively sealing water, acids, gases, and more.

[Selection and installation of oil seals]
When choosing and installing oil seals, consider factors like the shaft's rotation speed, temperature, pressure, and medium properties. Ensure vertical installation to avoid tilting, and apply grease to the lip to reduce dry grinding, thus enhancing the seal's longevity and efficiency.
