Hollow Pass-Thru Cylinders
Our pneumatic and hydraulic, hollow pass-thru cylinders are designed for maximum versatility. With a precision-machined thru-hole, they allow air, vacuum, cables, or mechanical linkages to pass directly through the centerline—making them ideal for robotics, automation, and custom tooling. Streamline your design with axial pushing, pulling or clamping.
Each unit can be tailored in size, porting, and mounting style, to match your application, from compact steel or bronze models to large anodized aluminum and stainless steel bodies. This unique design opens up possibilities that standard cylinders can’t achieve—combining powerful actuation with true pass-thru functionality.
Mack Automation manufactures these cylinders in a wide variety of bore sizes, strokes, and materials, offering both standard and fully customized solutions to fit your exact needs.
