Parker 1.12NLPE91.00 Single Acting Air Cylinder

Product Description

The PARKER 1.12NLPE91.00 is a single acting rodless air cylinder designed for pneumatic linear motion applications in industrial and mechanical systems. With a 1-1/8 inch bore and a 1 inch stroke, this compact cylinder delivers controlled single-direction actuation using shop air. The body is constructed from steel and aluminum, keeping weight low at 0.43 pounds while maintaining structural rigidity. The piston rod measures 0.5 inches in diameter and is threaded 5/16-24 for direct mechanical attachment. Nitrile butadiene rubber seals provide reliable air retention across typical operating temperature ranges. Pneumatic technicians and maintenance mechanics install this type of cylinder in automated equipment, fixtures, and light-duty actuation assemblies.

This cylinder fits applications requiring compact single acting pneumatic actuation where return travel is handled by a spring or external force. The 1/8 NPT port accepts standard push-in or threaded fittings common in low-flow pneumatic circuits. Head or cap mounting gives installers flexibility to orient the cylinder to suit the machine frame or bracket configuration. It is well suited to small automated assemblies, clamping fixtures, indexing mechanisms, and similar light industrial tasks where stroke length and bore size fall within its rated range.

• 1/8 NPT port accepts standard pneumatic fittings
• 5/16-24 threaded rod end for direct mechanical connection
• Nitrile butadiene rubber seals for reliable air retention and cycle life
• Head or cap mounting style supports flexible installation orientations

Compatibility

Designed as an OEM-style replacement or direct-fit component for pneumatic systems requiring a single acting rodless air cylinder with a 1-1/8 inch bore and 1/8 NPT porting.

Installation Notes

Installation should be performed by a qualified pneumatic technician or industrial maintenance mechanic. Depressurize the air supply and relieve any residual line pressure before removing or installing the cylinder. Ensure port fittings are compatible with the 1/8 NPT thread and that the air supply is clean, dry, and within the cylinder manufacturer's recommended pressure range. Secure mounting fasteners to the head or cap mount points before applying air pressure.
