Parker 1.25USU1604.00 Air Cylinder 1.25 in Bore 4 in Stroke

Product Description

The PARKER 1.25USU1604.00 is a double acting rodless air cylinder designed for linear motion control in pneumatic systems. 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 a steel and aluminum combination, with nitrile butadiene rubber (NBR) seals suited for standard compressed-air service. A 1/8 NPTF port accepts standard pneumatic fittings. This cylinder is installed by industrial maintenance technicians, automation specialists, and mechanical contractors working on pneumatic actuation circuits in production and process equipment.

This cylinder is suited for use in light-duty to medium-duty pneumatic actuation applications where a universal mounting style is required. The universal mount configuration supports flexible integration into a range of machine frames and equipment bases. With a 3/8-inch rod diameter and 3/8-24 male rod thread, it connects directly to standard pneumatic linkages and end effectors. Typical installations include conveyor systems, automated fixtures, and industrial machinery requiring compact, reliable linear actuation.

Key Features

• Double acting design allows powered extension and retraction for positive force in both directions
• 1.25-inch bore with 4-inch stroke delivers consistent linear travel for light-to-medium duty cycles
• 200 psi maximum working pressure compatible with standard shop-air and industrial pneumatic systems
• Universal mount style supports flexible installation orientations and machine integration
• 1/8 NPTF port accepts standard pneumatic fittings without thread sealant concerns
• NBR seals provide reliable performance in standard compressed-air service environments

Compatibility

Designed as an OEM-style replacement or direct-fit component for pneumatic actuation systems requiring a double acting rodless air cylinder with a 1.25-inch bore, 4-inch stroke, and universal mount configuration.

Installation Notes

Installation should be performed by a qualified industrial maintenance technician or pneumatic systems specialist. Depressurize and lock out the pneumatic circuit completely before removing or installing the cylinder. Verify that supply-line pressure does not exceed the 200 psi rated maximum and that fittings are compatible with 1/8 NPTF port threads. Secure all mounting hardware to the machine frame before returning the system to service.
