Parker 1.25USU1603.00 Air Cylinder 1.25in Bore 3in Stroke

Product Description

The PARKER 1.25USU1603.00 is a double acting rodless air cylinder designed for industrial pneumatic motion control applications. It features a 1.25-inch bore and a 3-inch stroke, delivering reliable linear actuation in both directions using compressed air. The cylinder body is constructed from steel, aluminum, and stainless steel, with nitrile butadiene rubber seals rated for a maximum working pressure of 200 psi. The 3/8-inch rod with 3/8-24 male thread and 1/8 NPTF port connection make this unit straightforward to integrate into existing pneumatic circuits. Mechanical and automation technicians working in manufacturing, assembly, and industrial process environments are the primary installers.

This cylinder is suited for light-duty to medium-duty double acting pneumatic applications where compact stroke length and a universal mounting style provide layout flexibility. The universal mount accommodates a range of fixture configurations without requiring a custom bracket. Typical install scenarios include actuator-driven positioning, clamping, and indexing tasks in automated equipment. The 1/8 NPTF port is compatible with standard 1/8-inch pneumatic fittings used widely in industrial plumbing.

Key Features

• Double acting design provides powered extension and retraction for positive control in both directions
• 1.25-inch bore and 3-inch stroke suit compact linear motion requirements
• Maximum working pressure of 200 psi
• Universal mount style accommodates multiple mounting configurations
• 1/8 NPTF port compatible with standard industrial pneumatic fittings
• Stainless steel body components with nitrile butadiene rubber seals for corrosion resistance and reliable sealing

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial pneumatic systems requiring a 1.25-inch bore double acting air cylinder with universal mounting and 1/8 NPTF porting.

Installation Notes

Installation should be performed by a qualified mechanical or pneumatic technician. Depressurize and lock out the pneumatic supply line before removing or installing any cylinder. Verify all fittings and port connections are properly sealed and torqued to fitting manufacturer specifications before returning the system to operating pressure. Ensure the mounting configuration and alignment are confirmed before cycling the cylinder under load.
