What are the advantages of the molded PTFE oil seals?

Update:2018-06-27

What are the most outstanding advantages of PTFE oil seals? DSH Seals tell you that the most outstanding features embody in using temperature, friction system, high speed resistance etc.

1. The using temperature range of sealing lip is wide. PTFE seal can normally work during -200-+260℃.

2. Friction factor(≤0.2μ) is the 1/4 of FPM, so greatly reducing the heat of friction in the use of oil seals, can decline the carbon deposition of rubber lips.

3. High speed resistance, the working speed about rotary shaft can be reached more than 30m/s.

4. The adoption of double thread groove structure improved the movement about lip with axis and reinforced the function of sealing lip. Sealing is more reliable.

5. Oil resistance design, can prevent the static leakage of oil seals.

6. The molded craft is the same as manufacturing ordinary rubber oil seals, so the cross-section and size of thread groove is stable, the quality is also reliable.

Oil seal is a mechanical element used to seal grease (oil is the most common liquid material in the drive system, also refers to the general liquid material meaning). It isolates the parts that need lubrication in the transmission part from the output part, so that it will not allow lubrication. Oil leakage. Static seal and dynamic seal (usual reciprocating motion) seal is called oil seal.
