Circular bellows

Circular bellows are supplied sewn, glued or heat-sealed. They are used when a very short compressed length is required or when good resistance to rotation is needed. They can be fixed using a flat-face or ring-face flange. To facilitate assembly they may be made with a lengthwise opening. In this way, they can be fitted without having to dismantle the part needing protection.

CLOSED LENGTH/TOTAL EXTENSION

Measurements available directly from the machine or from the control panel. * Basic measurements for the construction of the bellow

*ET= total extension

CO= stroke

*PC= closed length

*A= bellows external diameter

B= bellows internal diameter
