Parker 1458040075 Air Cylinder Rod Eye Knuckle

Product Description

The PARKER 1458040075 is a rod eye knuckle accessory designed for use with Parker air cylinders. This fitting attaches to the cylinder rod end to provide a pivoting connection point, allowing the cylinder to transmit linear force while accommodating minor angular misalignment in the load path. It is used in pneumatic actuation systems found in industrial machinery, automation equipment, and process control applications. Licensed industrial mechanics and millwrights typically install this component as part of a cylinder mounting and linkage assembly. The part weighs 3 pounds and ships as a single-piece unit.

This rod eye knuckle is intended for use with Parker 3MA and 4MA Series air cylinders. These series are commonly deployed in light to medium-duty industrial pneumatic circuits where clevis or pivot-style rod end connections are required. The accessory provides the pivot joint that allows the cylinder to articulate freely without binding, which is critical in applications where the load is not perfectly aligned with the cylinder centerline.

Key Features

• Pivot-style rod end connection accommodates angular misalignment in the load path
• Designed specifically for Parker 3MA and 4MA Series air cylinders
• Sold as a single-piece unit with no minimum order beyond one piece
• Attaches to cylinder rod end for clevis-style linkage configurations

Compatibility

Designed for use with Parker 3MA and 4MA Series air cylinders as specified by the manufacturer.

Installation Notes

Installation is typically performed by a licensed industrial mechanic or millwright working on pneumatic actuation systems. De-energize the pneumatic circuit and bleed all line pressure before removing or installing any cylinder accessory. Ensure the rod end threads are clean and that the knuckle is fully engaged and secured before returning the system to service. Follow applicable OSHA and plant safety lockout/tagout procedures during installation.
