Parker 1.25NSU1605.00 Air Cylinder 1.25 in Bore 5 in Stroke

Product Description

The PARKER 1.25NSU1605.00 is a double acting rodless air cylinder designed for linear pneumatic motion control in industrial automation, manufacturing, and mechanical assembly applications. With a 1.25-inch bore and a 5-inch stroke, it delivers controlled bidirectional actuation using shop air. Maximum working pressure is 200 psi. The cylinder body combines steel and aluminum construction for a balance of strength and weight. A 3/8-inch male rod with 3/8-24 thread provides a direct connection point for tooling or load attachments. Nitrile butadiene rubber seals provide reliable performance across standard temperature and pressure ranges. Installation is handled by qualified pneumatic or mechanical technicians.

This cylinder is suited for light-to-medium duty pneumatic actuation tasks in industrial and commercial settings. Its nose mount configuration allows direct mounting to machine frames, fixtures, or custom brackets. The 1/8 NPTF port accepts standard fittings used in compressed air plumbing. The double acting design means both extension and retraction strokes are powered, making it appropriate for applications that require controlled force in both directions, such as clamping, indexing, pressing, or part transfer on automated equipment.

Key Features

• Double acting design delivers powered extension and retraction strokes up to 200 psi
• 1.25-inch bore and 5-inch stroke for compact linear travel
• Steel and aluminum body construction for durability with reduced overall weight
• 3/8-inch male rod with 3/8-24 thread for direct load or tooling attachment
• 1/8 NPTF port accepts standard compressed air fittings
• Nitrile butadiene rubber seals rated for standard industrial pneumatic service
• Nose mount style for straightforward integration into machine frames and fixtures

Compatibility

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

Installation Notes

Installation should be performed by a qualified pneumatic or mechanical technician. Depressurize and lock out the compressed air supply before removing or installing any cylinder. Verify that all fittings and air lines are rated for the system operating pressure before connecting to the 1/8 NPTF port. Ensure the nose mount is secured to a rigid surface and that rod alignment with the load is correct to prevent side loading and premature seal wear.
