Name: JJL hinge bellows
has been committed to hinge bellows technology research, has extensive experience in the hinge bellows experts to provide you with professional hinge bellows product is your ideal choice!
hinge bellows Features:
JJL hinge bellows is over, take over the bellows and is connected with a pair of hinges form. Compensator hinges have the ability to withstand the internal pressure thrust.
Hinge bellows features: stainless steel compensator for the absorption of single-plane angular displacement. Hinge bellows installation considerations 1. Stainless steel bellows compensator two or three supporting the use of 2 stainless steel compensator installed at the hinge rotation plane must be consistent with the displacement plane.
