No sliding friction with `top hat’ seals

In applications such as air cylinders and valve actuators which require long piston strokes, Ceetak says its `top hat’ rolling diaphragm seals provide maximum performance without sliding friction.

Shaped like a top hat, the diaphragm is installed with its centre securely fastened to the piston head and its rim gripped between the faces of the cylinder retention flanges. The seal permits piston travel as a result of its annular moulded contours, which roll smoothly with the motion and eliminate sliding friction.
