Parker 1.25NSU1604.00 Air Cylinder 1.25 in Bore 4 in Stroke

Product Description

The PARKER 1.25NSU1604.00 is a double acting rodless air cylinder designed for industrial pneumatic motion control applications. It features a 1.25-inch bore and a 4-inch stroke, with a maximum working pressure of 200 psi. The cylinder body is constructed from steel and aluminum, combining structural rigidity with reduced overall weight. A nitrile butadiene rubber (NBR) seal package provides reliable performance across typical compressed-air service conditions. The nose mount configuration allows direct inline installation into machine frames, actuator assemblies, and automated tooling setups. This unit is typically installed by maintenance technicians and industrial automation specialists working on pneumatic systems.

This cylinder is suited for linear motion tasks in light to medium industrial environments. Its 1/8 NPTF port accepts standard compressed-air fittings and integrates cleanly into existing pneumatic circuits. The 3/8-inch male rod with 3/8-24 thread facilitates direct coupling to load-bearing components. Common applications include small-format machine slides, clamping fixtures, and indexing mechanisms where a compact, rodless profile is preferred. The nose mount style positions the port at the front of the cylinder for simplified plumbing in tight installations.

Key Features

• Double acting operation for powered extension and retraction strokes
• 1.25-inch bore and 4-inch stroke in a nose-mount, rodless configuration
• 200 psi maximum working pressure for reliable pneumatic circuit integration
• 1/8 NPTF port compatible with standard compressed-air fittings
• Steel and aluminum body construction for durability with reduced weight
• NBR seals suitable for standard compressed-air service
• 3/8-24 male rod thread for direct load coupling

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial pneumatic systems requiring a 1.25-inch bore, 4-inch stroke, nose-mount, double acting air cylinder with 1/8 NPTF porting.

Installation Notes

Installation should be performed by a qualified maintenance technician or pneumatic systems specialist. Depressurize and isolate the pneumatic circuit completely before removing or installing the cylinder. Verify port thread compatibility and use appropriate thread sealant rated for compressed-air service on all NPTF connections. Confirm that the mounting surface and load alignment are correct before returning the system to pressure.
