Parker 1.12NLP91.00 Rodless Air Cylinder 1-1/8 in Bore

Product Description

The PARKER 1.12NLP91.00 is a double acting rodless air cylinder designed for pneumatic linear motion in industrial and automation applications. With a 1-1/8 inch bore and 1 inch stroke, it delivers controlled bidirectional movement at operating pressures up to 250 psi. The cylinder features an aluminum body with steel components, keeping weight low at 0.41 pounds while maintaining structural durability. Port connections are 1/8 NPT, and the unit supports head or cap mounting configurations, giving installers flexibility in how the cylinder is oriented and fastened within a pneumatic assembly. Licensed pneumatic or automation technicians typically handle installation and integration.

This cylinder suits compact pneumatic control systems where a traditional rod-style cylinder would require additional clearance. The rodless design keeps the overall envelope small, making it well suited for light-duty pick-and-place, clamping, indexing, or actuator applications in automated equipment. Its 2 inch overall width allows integration into tight machine frames. The 1/8 NPT ports are compatible with common pneumatic fittings found in industrial plumbing and control circuits.

Key Features

• Double acting operation enables powered extension and retraction without return springs
• 1-1/8 inch bore with 1 inch stroke for compact, precise linear motion
• Maximum working pressure of 250 psi for reliable pneumatic performance
• 1/8 NPT ports accept standard pneumatic fittings
• Aluminum body reduces overall assembly weight
• Head or cap mount style provides flexible installation orientation
• Nitrile butadiene rubber seals offer resistance to petroleum-based lubricants in airline systems

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial pneumatic systems requiring a double acting rodless cylinder with a 1-1/8 inch bore, 1/8 NPT porting, and head or cap mounting.

Installation Notes

Installation should be performed by a qualified pneumatic or automation technician. Depressurize and lock out the pneumatic circuit before removing or installing any cylinder. Verify that supply pressure does not exceed 250 psi and that all fittings are torqued and sealed according to the fitting manufacturer specifications. Consult applicable machine safety standards and local regulations before placing the cylinder into service.
