Product Description

Oil seals, commonly known as rotary shaft seals, are pivotal in maintaining the delicate balance needed to keep grease, liquids, or dirt precisely sealed. They are essential components in any rotating or moving machinery assembly, expertly stabilizing the crucial interaction between static and dynamic parts. The classic oil seal is crafted from three fundamental elements:
1. Sealing Material: Constructed from resilient rubber components, offering superior flexibility and exceptional durability. 2. Metal Casings: Impart structural integrity and robust support to the seal. 3. Springs: Intensify the sealing pressure and ensure a secure, airtight fit. This adaptable sealing assembly is engineered to accommodate a comprehensive range of mechanical applications.
Our extensive assortment of oil seal types encompasses: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and more. Each is meticulously designed to satisfy a wide variety of operational specifications and demands.
We proudly present a diverse selection of premium rubber materials for crafting oil seals. These materials are strategically selected to endure a variety of operational conditions. Our high-performance rubbers are expertly formulated to resist an extensive array of chemicals and to withstand extreme temperatures, ensuring exceptional reliability in both scorching and frigid environments.

[Introducing Our Superior Oil Seal Materials]

We excel in the production of customizable non-standard oil seals, using top-tier materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet specific industrial applications and challenges.

[Understanding the Oil Seal and Its Sealing Principle]

The oil seal operates with remarkable ingenuity, forming a vital oil film through the precise engagement between its lip and the shaft. It leverages spring tension and material elasticity for effective dynamic sealing. As rotation occurs, the generated frictional heat causes the lip to constrict, enhancing seal efficiency. When idle, the lip remains in contact, effectively maintaining seal integrity.

[Diverse Fields of Oil Seal Application]

Our oil seals are critical in engines, gearboxes, hydraulic pumps, reducers, and various machinery, especially under harsh conditions involving high temperatures, rapid speeds, and corrosive substances, where conventional rubber oil seals may fail. Notably, PTFE oil seals boast a durability up to 20 times greater than standard options, proficiently sealing water, acid, gas, and other mediums.

[Guidance on Oil Seal Selection and Installation]

For peak performance, comprehensively assess factors such as shaft rotation speed, temperature, pressure, and medium characteristics. Ensure precise vertical installation to avoid misalignment and apply a layer of grease to the lip to prevent dry friction, thereby extending the product's lifespan.

[Detailed Introduction to Oil Seal Materials]

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.

[Exploring the Core Structure Type of Oil Seals]

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 Our High-Quality Oil Seals]

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
