Parker 2.50NLPR91.00 Rodless Air Cylinder 2.5 in Bore 250 Psi

Product Description

The PARKER 2.50NLPR91.00 is a double acting rodless air cylinder designed for linear motion applications in pneumatic systems. With a 2.5-inch bore and a 1-inch stroke, it delivers controlled bidirectional actuation using compressed air. Maximum working pressure is 250 psi. The cylinder features an aluminum body with steel components and a nitrile butadiene rubber (NBR) seal, making it well suited for general industrial and automation environments. Licensed HVAC technicians, millwrights, and industrial maintenance mechanics are the typical installers. The 1/4 NPT port provides a standard connection point for compressed air supply lines.

This cylinder is used in industrial automation, pneumatic control panels, and light-duty linear actuation setups where a compact stroke length is required. The head or cap mounting style allows flexible installation in tight spaces. At 2.5 inches overall length and 3.75 inches overall width, the unit fits into compact machinery frames and automated assembly fixtures. It is appropriate for both OEM equipment builds and field replacement in existing pneumatic systems.

Key Features

• Double acting design enables bidirectional force output using compressed air
• 2.5-inch bore provides substantial actuation force at rated pressure
• 250 psi maximum working pressure supports standard shop-air systems
• 1/4 NPT port fits common pneumatic fittings and manifold connections
• Aluminum body with NBR seals balances light weight with durability
• Head or cap mount style allows versatile installation orientations

Compatibility

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

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or industrial mechanic. Depressurize and lock out the air supply before removing an existing cylinder or installing this unit. Verify port orientation and mounting configuration before securing the cylinder to the frame. Follow applicable OSHA and local machine guarding codes when integrating this cylinder into automated equipment.
