(1)Features
•Single seal
•Loosely inserted seal face provides self-adjusting capability
•In-house manufactured sliding parts
(2)Advantages
The EA560 is self-adjusting to shaft misalignments and
deflections because of the loosely inserted seal face
as well as the ability of the bellows to stretch and tighten.
The length of the contact area of the bellows with
the shaft is an optimum compromise between ease of
assembly (less friction) and sufficient adhesive force
for torque transmission. Additionally the seal fulfills very
specific leakage requirements. Because the sliding parts
are made in-house, a wide variety of special needs can
be accommodated.
