Your specification

Configure your product requirement

Enter the capacity and site requirements you need. Your selections carry into the RFQ and remain editable before submission.

Essential operating requirements

Select a documented reference, or leave blank and describe an unlisted requirement. Reference ratings remain separate from your requested specification.

Additional dimensions and application details
Equipment identification & spare parts

Identify the installed equipment and the part you need. Add nameplate photos, drawings or a parts-list extract in the RFQ attachments step.

Next: contact details, quantity and delivery. Leave unknown requirements blank and request help in the RFQ.

Applications

Short-stroke clamping, assembly stations, packaging and compact automation.

Selection guidance

Documented bores are 20, 25, 32, 40, 50, 63, 80 and 100 mm. The 25 and 100 mm stroke references are standard examples; other documented or custom strokes require matching to the precise execution and mounting dimensions.

Technical notes

Maximum pressure is not proof pressure. Rubber bumpers, auto air cushioning, double-rod, smooth and high-temperature executions are separate configurations. A magnetic piston does not mean a sensor is included.
