Oil Seal Types And Applications (2)

Outer skeleton double lip FW
Double lip exposed skeleton rubber oil seal with auxiliary lips, slim waist, good tracking performance, high stiffness, and good coaxiality.
Ordinary oil seal with dust lip can prevent dust and withstand medium pressure<0.05MPa. Speed ≤ 15m/s.
Prefabricated single lip FZ
The outer skeleton oil seal is assembled by rolling the inner and outer skeleton, and has high installation accuracy, fast heat dissipation, and heavy load characteristics.
Suitable for heavy load conditions under high temperature and high speed conditions, with medium pressure ≤ 0.05MPa and maximum linear speed ≤ 15m/s.
Unidirectional reflux type right-handed SR, left-handed DL
There are oblique ribs with angles in the air measurement of the lips, which utilize the principles of fluid mechanics to generate a unidirectional pumping effect and have a reflux effect.
It is related to the direction of rotation of the shaft. Due to its reflux effect, the radial force is smaller than that of ordinary oil seals, reducing wear and heat generation, and improving service life. It is suitable for media pressure<0.05MPa, with a speed of ≤ 20m/s.
Pressure resistant NY
Short lips and thick waist, with pressure resistance, working pressure ≤ 3MPa.
Suitable for applications with medium pressure ≤ 3MPa, suitable for shaft end oil seals of high-pressure pumps, with a PV value generally ≤ 8. Rotating axis speed ≤ 15m/s
