High quality oil seal TC 3Y 74*156*17.5/22 NBR half iron half glue

Short Description:

The TC oil seal isolates the part of the transmission part that needs to be lubricated from the output part, so that the lubricating oil will not leak. Static seals and dynamic seals (usually reciprocating) seals are called oil seals. The representative form of the oil seal is the TC oil seal, which is a fully covered rubber double-lip oil seal with a self-tightening spring. Generally speaking, the oil seal often refers to this TC skeleton oil seal. The TC profile is a shaft seal consisting of a rubber-coated metal cage, a main sealing lip with integrated spring and an additional anti-contamination sealing lip.

Oil seal basic information:

Oil seals are often referred to as grease, fluid, dirt or lip seals. Oil seals are an integral part of any assembly of rotating and moving parts.
They close the space between fixed and moving parts in mechanical equipment. In most applications, seals are either partially or temporarily immersed or simply exposed to splashes of lubricant, especially in engines, transmissions, gearboxes or axles. They are an essential part of almost all machines and vehicles in operation. Oil seals usually consist of three basic components: sealing element (nitrile rubber part), metal housing and spring. It is a widely used sealing element. The function of the seal is to prevent the leakage of the medium along the moving parts.

Features and performance requirements:

1. Good wear resistance, high tear resistance and good bending strength;

2. Tensile strength and elongation at break;

3. High temperature resistance (-30 degrees to +260 degrees);

4. Hardness (Shore 60-85 A);

5. Low compression rate;

6. Oil resistance, corrosion resistance, good solvent resistance, high mechanical strength and long service life;

material Low
NBR -40 120 Good resistance to alcohol,amines, petroleum oils, and
gasoline over a wide range of temperature. Also good resistance to caustic salts and fair acid. Poor in strong oxidants, chlorinated hydrocarbons, ketones, and esters
HNBR -25 140 HNBR is made from NBR by hydrogenation. It has high
temperature resistance, abrasion resistance and good
physical properties.
ACM -25 150 It is used in diaphragm, hose for automotive application.
Good resistance to heat, ozone and oil. Generally
attacked by water, alcohol, glycol and aromatic
hydrocarbons. The molecular structure contains ethyl acrylate (EA). Butyl acrylate (BA), and methoxy ethyl acrylate (MEA). High BA content get better low temperature resistance, and high MEA content get more oil resistance.
EPDM -40 125 Stable in polar fluids (alcohol, ketone, and glycol),
and hydrochloric acid. Due to the low specific gravity, it can compound with large amount filler.
VMQ -60 125 The most widely temperature ranges for application.
Good weather and ozone resistance, but poor mechanical property and chemical resistance.
FKM -20 250 Fluoroelastomers have a high degree of chemical
stability and are currently the best media resistance
of any elastomer. Type 26 fluoroelastomer resistant
to petroleum-based oils, diester oils, silicone ether
oils, silicic acid oils, inorganic acids, most organic, inorganic solvents, drugs and so on
