Norgren MN-4 Air Cylinder Mounting Nut 1-1/16 in Bore

Product Description

The NORGREN MN-4 is a replacement mounting nut designed for use with pneumatic air cylinders. It secures the cylinder to a mounting surface, providing a stable and reliable connection in compressed-air-driven systems. Sized for a 1-1/16 inch bore cylinder with 3/4 inch double-action configuration, this hardware component is a standard service part in pneumatic assemblies. It is installed by industrial maintenance technicians, millwrights, and pneumatic system specialists in light and medium-duty automation and motion-control applications.

This mounting nut is suited for double-action pneumatic cylinder installations where both extend and retract strokes are powered by compressed air. It fits cylinders with a 1-1/16 inch bore diameter and is appropriate for use in manufacturing, packaging, material handling, and similar industrial environments. The MN-4 is a direct accessory part intended for use during cylinder installation, rebuild, or replacement workflows.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic system assembly. De-pressurize the pneumatic circuit completely and lock out the air supply before beginning any mounting hardware service. Use appropriately sized hand tools and follow the cylinder manufacturer torque guidelines for threaded mounting components. Ensure threads are clean and free of debris before installation to prevent cross-threading or improper seating.
