Product Description

Oil seals, often known as rotary shaft seals, serve as vital components in machinery by effectively sealing grease, liquids, or dirt. As an indispensable part of any rotating or moving assembly, the oil seal ensures the stability and functionality of the space between stationary and moving parts. Typically, this essential component is composed of three fundamental elements:
A robust sealing material (rubber component), durable metal casings, and resilient springs. Together, they form a versatile sealing assembly that's crafted for reliability.
Our oil seal types include an extensive range: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, to name a few.
We present a broad selection of premium rubber materials for manufacturing oil seals, each chosen to ensure optimal performance across various operating conditions. These high-quality materials are engineered to withstand diverse chemicals and endure extreme temperatures, whether soaring high or plummeting low.
[Comprehensive 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.

Our customizable non-standard oil seals are available in an array of materials such as high-performance fluorine rubber, versatile silicone rubber, durable fine rubber, and resilient propylene rubber.

[Innovative Oil Seal Core Structure Types]

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)

[Critical 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 of Oil Seal and Sealing Technology]
The oil seal establishes an effective oil film through the precise contact between its lip and the shaft, achieving superior dynamic sealing by leveraging spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, enhancing the sealing performance. When stationary, it maintains a firm contact to ensure an unbroken seal.

[Diverse Fields of Oil Seal Application]
Oil seals are extensively applied in engines, gearboxes, hydraulic pumps, reducers, and various other equipment, especially under conditions of high temperatures, high speeds, and exposure to corrosive media. They are the preferred choice where traditional rubber oil seals may fall short. Notably, PTFE oil seals offer longevity up to 20 times greater than conventional counterparts, sealing water, acids, gases, and other challenging media.

[Guidelines for Oil Seal Selection and Installation]
When selecting and installing oil seals, it's essential to evaluate factors such as rotation speed, temperature, pressure, and the medium's characteristics comprehensively. Ensuring the shaft is installed vertically prevents tilting, and applying grease to the lip reduces dry friction, enhancing seal longevity.
