Product Description

Oil seals, often referred to as rotary shaft seals, play an indispensable role in safeguarding mechanical systems by effectively sealing grease, liquids, or dirt. Essential to any rotating or moving assembly, oil seals maintain the crucial equilibrium between stationary and dynamic components in mechanical machinery. Typically, an oil seal comprises three fundamental elements:
1. Sealing Material: Expertly crafted from durable rubber components to ensure both flexibility and longevity. 2. Metal Casings: Deliver structural integrity and robust support to the seal. 3. Springs: Intensify the sealing pressure, ensuring a secure and tight fit. This adaptable sealing assembly is engineered to address a vast array of mechanical requirements.
Our extensive array of oil seal types encompasses TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and many more, skillfully tailored to meet diverse operational needs.
We proudly showcase a wide selection of meticulously curated rubber materials for oil seal production, chosen to excel under various operating conditions. Our high-performance rubbers are specifically designed to resist a broad range of chemicals and endure extreme temperatures, guaranteeing reliable performance in both high and low thermal environments.

[Introducing Our Superior Oil Seal Materials]

We excel in producing custom non-standard oil seals using top-tier materials such as fluorine rubber, silicone rubber, high-quality rubber, and propylene rubber, perfectly tailored to fulfill specific industrial demands.

[Understanding the Oil Seal and Its Sealing Principle]

The oil seal ingeniously establishes an oil film through the precise interaction between the lip and the shaft, expertly utilizing spring pressure and material elasticity for dynamic sealing. During rotation, frictional heat prompts the lip to contract, thereby augmenting the sealing efficacy. When at rest, the lip retains contact, safeguarding the seal's integrity.

[Diverse Fields of Oil Seal Application]

Our oil seals are crucial in engines, gearboxes, hydraulic pumps, reducers, and a myriad of machinery, particularly under challenging conditions characterized by high temperatures, high speeds, corrosive environments, or when traditional rubber oil seals fall short. Notably, PTFE oil seals can last up to 20 times longer than conventional ones, efficiently sealing water, acid, gas, and other mediums.

[Guidance on Oil Seal Selection and Installation]

To achieve optimal performance, carefully assess the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure correct vertical shaft installation to prevent tilting and apply grease to the lip to minimize dry grinding, thereby enhancing longevity.

[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
