CU Series Free Mount Cylinder

The CU Series Free Mount Cylinder is designed for compact automation systems where installation flexibility is essential. Its multi-surface mounting design allows direct installation from different directions, helping engineers optimize equipment layouts without additional brackets.

Available in double-acting and single-acting configurations, as well as optional non-rotating piston rod versions, the CU Series provides reliable linear actuation for positioning, clamping, and compact motion control applications. Its lightweight construction and maintenance-free operation make it an ideal solution for modern automated equipment.


CU Series Free Mount Cylinder

The CU Series Free Mount Cylinder is a space-saving pneumatic actuator developed for equipment with limited installation space and diverse mounting requirements. Unlike conventional compact cylinders that rely on dedicated mounting accessories, the CU Series supports direct installation from multiple surfaces, simplifying machine design and reducing assembly time. Its compact body and versatile mounting capability make it especially suitable for automated equipment requiring efficient use of available space.

Designed for consistent and reliable operation, the cylinder is available in double-acting, single-acting spring return, and spring extend configurations. An optional non-rotating piston rod further improves positioning accuracy in applications where rotational movement must be minimized.

Main Features

● Compact body with space-saving design

● Free multi-sided mounting for flexible installation

● Double-acting and single-acting models available

● Optional non-rotating piston rod

● Rubber cushions on both ends for smoother operation

● Stable linear motion with reliable repeatability

● Lightweight construction for compact equipment

● Maintenance-free non-lube operation

● Suitable for magnetic and non-magnetic versions

● Easy integration into automated machinery

Flexible Installation for Compact Equipment

The defining advantage of the CU Series is its free mounting structure, allowing engineers to install the cylinder from multiple directions without additional mounting accessories. This flexibility simplifies equipment design while reducing component count and assembly costs.

For applications requiring higher positioning stability, the optional non-rotating rod design minimizes unwanted piston rotation, achieving rotation accuracy of up to ±0.5° depending on bore size. Combined with rubber cushioning at both ends, the cylinder delivers smooth operation and extended service life during continuous cycling.
