Product Description

Oil seals, or rotary shaft seals, are the underappreciated champions of machinery, skillfully sealing grease, liquids, or dirt to guarantee seamless operation. These crucial components stabilize the gap between stationary and moving parts in mechanical equipment, providing unmatched reliability and efficiency. Typically, an oil seal is made up of three core elements: the sealing element, the metal case, and the spring.
The sealing assembly is a masterpiece of engineering, featuring a sealing material (rubber component), metal casings, and springs. This versatile design embodies the pinnacle of durability and reliability, ensuring sustained performance in demanding environments.
Explore our comprehensive range of oil seal types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the groundbreaking TC4, among others. Each type offers unique properties tailored to specific applications, ensuring the perfect fit for your operational needs.
Our selection of high-performance rubber materials for oil seals is unrivaled, engineered to resist a multitude of chemicals and withstand extreme temperatures. These materials are precisely crafted to perform under diverse operating conditions, whether confronting the searing heat or the biting cold.
[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.

For unique requirements, we offer customizable non-standard oil seals made from specialized materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber. Each material is carefully selected to provide bespoke solutions for your specific challenges, ensuring precision and performance.

[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 on an advanced principle, creating an oil film through the dynamic interaction between the lip and the shaft. Leveraging spring pressure and the intrinsic elasticity of the materials, it ensures a robust seal. During operation, frictional heat causes the lip to contract, enhancing the seal, while in rest mode, it maintains its grip to ensure continuous integrity.

[Oil seal application fields]
Our oil seals are critical in engines, gearboxes, hydraulic pumps, reducers, and more. They excel in high-temperature, high-speed, and corrosive environments, where conventional seals might falter. Consider our PTFE oil seals, which boast longevity up to 20 times that of standard seals, effectively sealing water, acids, gases, and more.

[Oil seal selection and installation]
When selecting and installing oil seals, consider factors such as the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure vertical installation to avoid tilting, and apply grease to the lip to reduce dry grinding, thereby extending the seal's longevity and efficiency.
