Parker 1.25DXPSRM04.00 Rodless Air Cylinder 1.25in Bore

Product Description

The PARKER 1.25DXPSRM04.00 is a double acting rodless air cylinder designed for industrial pneumatic motion control applications. Built with a stainless steel body, it delivers a 1.25-inch bore and a 4-inch stroke while handling maximum working pressures up to 250 psi. The rodless design keeps the overall footprint compact, making it suitable for tight linear-travel applications where a conventional rod-style cylinder would exceed available space. Licensed pneumatic system integrators and maintenance technicians install this type of actuator in automated machinery, conveyor systems, and fixture tooling where clean linear motion is required.

This cylinder is suited for light-to-medium duty industrial pneumatic systems requiring precise, bidirectional linear actuation. The double acting configuration uses air pressure on both sides of the piston, enabling controlled force on both the extend and retract strokes. The 1/8 NPTF port accepts standard compressed-air fittings and connects to conventional directional control valves. Double end or rear pivot mounting provides installation flexibility across a range of machine frame configurations. At 0.9 pounds, the unit is lightweight enough for mobile fixture or robotic end-of-arm tooling installations.

Key Features

• Stainless steel body for corrosion resistance in washdown or harsh-environment applications
• Double acting operation provides powered force on both extend and retract strokes
li>1.25-inch bore with 4-inch stroke for compact linear travel
• 250 psi maximum working pressure compatible with standard plant air supply systems
• 1/8 NPTF port for leak-resistant threaded connection to compressed air fittings
• Double end or rear pivot mount supports multiple mounting orientations
• Nitrile butadiene rubber (NBR) seals for reliable air retention across a broad temperature range

Compatibility

Designed as an OEM-style replacement or direct-fit pneumatic actuator for industrial double acting rodless cylinder applications requiring a 1.25-inch bore, 4-inch stroke, and 1/8 NPTF porting.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or millwright. Depressurize and lock out the compressed air supply before removing or installing any cylinder. Verify that supply pressure does not exceed 250 psi and that fittings used at the 1/8 NPTF port are rated for the system operating pressure. Confirm mounting hardware is appropriate for the double end or rear pivot configuration before securing the cylinder to the machine frame.
