Parker 1.25NSU1603.00 Air Cylinder 1.25 in Bore 3 in Stroke

Product Description

The PARKER 1.25NSU1603.00 is a double acting rodless air cylinder designed for linear motion applications in pneumatic systems. It features a 1.25 inch bore and a 3 inch stroke, delivering consistent bidirectional force through compressed air actuation. Rated to a maximum working pressure of 200 psi, the cylinder body is constructed from stainless steel and aluminum with nitrile butadiene rubber seals for durability across a range of industrial and automation environments. The nose mount configuration allows for straightforward panel or bracket installation. This cylinder is installed by industrial maintenance technicians and automation specialists working with pneumatic control systems.

This air cylinder is suited for light to medium duty pneumatic actuation tasks in manufacturing, assembly, and process automation applications. The 1/8 NPTF port accommodates standard compressed air line fittings. The 3/8 inch rod diameter with 3/8-24 male thread rod end allows direct coupling to tooling or load fixtures. The nose mount style supports compact inline installations where space is limited. Both residential and commercial industrial environments with existing pneumatic supply infrastructure are typical deployment contexts.

Key Features

• Double acting design provides powered extension and retraction for positive bidirectional control
• 1.25 inch bore and 3 inch stroke deliver precise short-travel linear actuation
• 200 psi maximum working pressure supports a wide range of pneumatic system operating conditions
• Stainless steel and aluminum body construction for corrosion resistance and reduced weight
• Nitrile butadiene rubber seals provide reliable performance with standard compressed air
• 1/8 NPTF port size is compatible with common pneumatic fittings and supply lines
• Nose mount style enables compact, direct-panel or bracket-based installation

Compatibility

Designed as an OEM-style replacement or direct-fit pneumatic cylinder for industrial automation systems requiring a double acting rodless cylinder with a 1.25 inch bore, nose mount configuration, and 1/8 NPTF porting.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician. Depressurize and lock out the compressed air supply before removing or installing any cylinder. Ensure all port fittings are rated for the operating pressure and that thread sealant compatible with pneumatic systems is used on NPTF connections. Verify that load alignment is correct before pressurizing to avoid side-loading the cylinder body.
