Parker 1.12NLPR91.00 Single Acting Rodless Air Cylinder

Product Description

The PARKER 1.12NLPR91.00 is a single-acting rodless air cylinder designed for linear pneumatic actuation in industrial and mechanical systems. It features a 1-1/8 inch bore and a 1 inch stroke, making it well-suited for compact automation applications where space is limited. The cylinder body is constructed from steel and aluminum, with nitrile butadiene rubber (NBR) seals for reliable performance in standard compressed-air environments. Port connection is 1/8 NPT. Typical installers include pneumatic system technicians and industrial maintenance mechanics working on automated equipment, fixtures, or machinery.

This cylinder is used in applications requiring controlled linear motion without an external rod protruding from the cylinder body. The compact overall length of 2.484 inches makes it a practical choice for tight-clearance assemblies. It supports head or cap mounting configurations, providing flexibility during integration into machine frames, brackets, or tooling plates. Single-acting design means air pressure drives motion in one direction, with a return spring or gravity completing the cycle.

Key Features

• Single-acting rodless design for compact linear actuation
• 1-1/8 inch bore with 1 inch stroke for short-travel applications
• 1/8 NPT port for standard compressed-air line connection
• Steel and aluminum body construction for durability and weight efficiency
• Nitrile butadiene rubber seals for compatibility with standard pneumatic service
• Head or cap mounting style for flexible installation orientations
• 5/16-24 rod thread size for precise mechanical connection

Compatibility

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

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or industrial mechanic. Depressurize the air supply and bleed residual line pressure before removing or installing any cylinder. Verify port alignment and thread engagement before applying system pressure. Follow applicable machine safety standards and lockout/tagout procedures during service.
