What type of mounted cylinders are used when the cylinder body must rotate during operation?

The correct choice is the type of mounted cylinder known as a clevis mount, which is designed to allow the cylinder body to rotate during operation. In applications where a pivot or rotational movement is necessary, the clevis mount provides a versatile link between the cylinder and the machine component it is acting upon. This is primarily because clevis mounts often incorporate a pin or a similar mechanism that permits swivel movement around a fixed point, accommodating the dynamic needs of machinery.

In scenarios where other mounting types, such as foot or flange, are used, the cylinder typically remains in a fixed position. Foot mounts secure the cylinder flat against a surface, preventing any rotation, while flange mounts attach the cylinder at a right angle to a surface, also restricting movement. Flush mounts, being designed for compact and limited-space applications, do not facilitate any rotational movement either.

By using a clevis mount, operators can ensure that the cylinder can rotate as needed, thereby enhancing the effectiveness of the pneumatic system in applications that require such movement.
