Rolling rubber diaphragms are special diaphragms shaped like top hats which provide the properties both of bellows and diaphragms.
The rolling diaphragms have deep folding parts, which allow smooth rolling action.
A long stroke is possible, and the effective pressure receiving area will be maintained the same throughout the operation.
Because the Rolling Rubber Diaphragm will move with a rolling action, it will not be necessary to pay special attention to the surface finish, materials, and hardness of the piston and the cylinder.
In addition, these rolling rubber diaphragms can respond to minute pressure variations, greatly contributing to improving the performance of equipment in the air pressure and liquid pressure control fields.
The design of the rolling rubber diaphragms enables their use without any lubrication. The rolling action of this type of diaphragms allows no friction loss in addition to extremely small hysteresis loss.
