AS-BJ80 metal bellow mechanical seal

Model NO.: AS-BJ80

Description：
Our AS-BJ80 is the ideal seal for general-purpose applications, especially good for low-temperature applications found in the chemical, water and waste water, pulp and paper, and utility industries. The seal is available with hard faces for abrasive applications and a wide range of elastomers to cover a broad range of applications.

Bellows Design Features:
⑴Optimum 45° tilt angle
⑵Three-sweep radius
⑶Static secondary seal
⑷Light spring loads

Welded Metal Bellows Bellows Advantages:

Background knowledge:
Production processes of welded metal bellows:
Welded metal bellows is to stamp metal sheets of certain width into wave washer type plates, and weld the inner circumferences of the two wave plates to make a V-shaped semi-finished product, and then overlap several semi-finished products before welding the outer circumference, and finally weld the front and rear ring seats to form the specified bellows. The main process is: punching and forming of wave plates → cleaning → inner seam welding → outer seam welding → welding front and rear seat rings → inspection → heat treatment → inspection.
