Product Description

Oil seals, often known as rotary shaft seals, are crucial components in mechanical systems, indispensable for sealing grease, liquids, or dirt. These essential devices stabilize the space between stationary and moving parts, ensuring the seamless operation of any rotating assembly. An oil seal is typically composed of three core elements:
A robust sealing material made from high-quality rubber, durable metal casings, and resilient springs, comprising a versatile and reliable sealing assembly.
Our offerings include a broad range of types: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and more, to meet diverse requirements.
We present a wide array of premium rubber materials tailored for oil seal production, ensuring optimal performance across various operating conditions. These top-tier materials withstand diverse chemicals and extreme temperatures, whether scorching or freezing.
[Introductory Guide 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.

We specialize in customizable non-standard oil seals crafted from superior materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, catering to specific requirements.

[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

[Principles Behind Oil Sealing Technology]
The oil seal operates by forming an oil film via the interaction of the lip and shaft, achieving a dynamic seal through spring pressure and inherent material elasticity. As it rotates, frictional heat causes the lip to contract, enhancing the seal; when idle, it maintains contact to preserve integrity.

[Applications and Domains for Oil Seals]
Our oil seals find extensive applications in engines, gearboxes, hydraulic pumps, reducers, and more, especially under high temperature, high-speed, or corrosive conditions where conventional seals falter. For instance, PTFE oil seals can endure up to 20 times longer than traditional variants, effectively sealing water, acid, gas, and additional media.

[Guidelines for Selecting and Installing Oil Seals]
Carefully consider the shaft's rotation speed, temperature, pressure, and medium characteristics for optimal installation. Ensure the vertical alignment of the shaft to prevent tilting and apply grease on the lip to minimize wear and tear due to dry friction.
