Parker MC4550M4 Male Button Shock Absorber M45 X 1.5

Product Description

The PARKER MC4550M4 is a male button shock absorber designed to decelerate and stop moving loads in industrial automation, pneumatic, and hydraulic systems. The unit features a 0.5 inch rod diameter, a 1.75 inch outside diameter, and a 1.91 inch stroke length, with an overall length of 7.69 inches. The M45 x 1.5 threaded body allows for secure, adjustable mounting in machine frames, end-of-stroke positions, and actuator assemblies. It weighs 2.69 pounds. Maintenance technicians and automation engineers typically specify and install this component in production machinery, transfer lines, and material handling equipment where controlled deceleration is required.

This shock absorber is suited for industrial applications where end-of-stroke impact energy must be absorbed and dissipated rather than transferred to the machine structure. Typical installations include pneumatic cylinder end stops, linear slide deceleration points, and automated assembly equipment. The male button contact style is appropriate for applications where a flat, centered contact point is needed to engage moving platens, carriages, or tooling. It is installed by machine builders, millwrights, and industrial maintenance technicians working on new builds or retrofits.

Key Features

• Male button absorber type provides flat, centered contact for consistent deceleration of platens and carriages
• 0.5 inch rod diameter and 1.91 inch stroke length accommodate moderate-energy industrial stop applications
• 1.75 inch outside diameter fits standard machine frame bores and mounting blocks
• M45 x 1.5 threaded body allows adjustable depth positioning within mounting fixtures
• 7.69 inch overall length suits deep-threaded mounting configurations
• Single-unit packaging with no minimum order quantity requirement beyond one piece

Compatibility

Designed as an OEM-style replacement or direct-install shock absorber for industrial automation and pneumatic machinery requiring an M45 x 1.5 threaded male button unit with a 1.75 inch outside diameter and 1.91 inch stroke.

Installation Notes

Installation should be performed by a qualified millwright, automation technician, or mechanical maintenance professional. De-energize and lock out all pneumatic, hydraulic, and electrical energy sources before removing or installing the shock absorber. Verify thread engagement depth and ensure the mounting surface is clean and free of debris before torquing the body into position. Confirm stroke alignment with the moving load contact point before returning the system to service.
