Parker 2.50NLPE91.00 Rodless Air Cylinder 2.5 in Bore 250 Psi

Product Description

The PARKER 2.50NLPE91.00 is a double acting rodless air cylinder designed for linear motion control in pneumatic systems. It features a 2.5-inch bore and a 1-inch stroke, with a maximum working pressure rating of 250 psi. The body is constructed from aluminum with steel components, keeping weight low while maintaining structural integrity. A 1/4 NPT port accepts standard pneumatic fittings. This cylinder is installed by industrial maintenance technicians and automation specialists in factory, assembly, and process control environments where compact, rodless linear actuation is required.

This cylinder suits applications where space constraints prevent the use of a conventional rod-style cylinder. Its head or cap mounting style provides flexibility for inline or end-mount configurations. The 3.75-inch overall width and 3.844-inch body length make it well suited for tight panel or machine-frame installations. Typical use cases include guided linear slides, part transfer mechanisms, and actuator stages in pneumatic automation equipment.

Key Features

• Double acting design provides powered motion in both extend and retract directions
• 2.5-inch bore delivers substantial force output at rated pressure
• 1-inch stroke length for compact, short-travel linear actuation
• 250 psi maximum working pressure for compatibility with standard shop air systems
• Aluminum body construction reduces overall assembly weight
• Nitrile butadiene rubber (NBR) seals provide resistance to standard pneumatic lubricants and moisture
• 1/4 NPT port accepts common pneumatic push-to-connect and compression fittings

Compatibility

Designed as an OEM-style replacement or direct-fit component for pneumatic automation systems requiring a double acting rodless cylinder with a 2.5-inch bore and 1/4 NPT porting.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or industrial maintenance professional. Depressurize and lock out the pneumatic supply line before removing or installing the cylinder. Verify that supply air is clean, dry, and within the 250 psi rated limit before commissioning. Ensure all NPT port connections are sealed with an appropriate thread sealant compatible with pneumatic service.
