Parker MC4550-4 Male Button Shock Absorber 1.91 in Stroke

Product Description

The PARKER MC4550-4 is a male button-style shock absorber designed to decelerate moving loads and dissipate kinetic energy in industrial automation and motion control applications. It features a 0.5-inch rod diameter, a 1.75-inch outside diameter, and a 1.91-inch stroke length, making it suited for compact installations where controlled deceleration is required. The 1-3/4-12 threaded body provides a secure, vibration-resistant mount in actuator end caps, brackets, and tooling plates. Licensed maintenance technicians, machine builders, and automation engineers typically specify and install this component in pneumatic and mechanical systems requiring repeatable cushioning performance.

This shock absorber is appropriate for use in industrial machinery, assembly line equipment, pick-and-place systems, and other automated handling applications where end-of-travel impact control is critical. The male button end style transfers deceleration force directly through contact with a moving carriage, gripper, or tooling surface. With an overall length of 7.69 inches, it fits standard mounting configurations common in mid-range automation equipment. It is sold as a single unit and is intended for professional installation in controlled production environments.

Key Features

• Male button end style for direct contact deceleration of moving loads
• 0.5-inch rod diameter provides a robust interface for mid-range load capacities
• 1.91-inch stroke length allows effective energy absorption over a compact travel range
• 1-3/4-12 threaded body enables secure, adjustable positioning in mounting hardware
• 1.75-inch outside diameter suits standard industrial shock absorber mounting bores
• 7.69-inch overall length supports typical actuator and bracket clearance requirements

Compatibility

Designed as an OEM-style replacement or direct-fit shock absorber for industrial automation assemblies requiring a male button type unit with a 1-3/4-12 thread, 0.5-inch rod diameter, and 1.91-inch stroke.

Installation Notes

Installation should be performed by a qualified mechanical or automation technician. De-energize all pneumatic, hydraulic, and electrical circuits and relieve any stored pressure before servicing or replacing shock absorbers. Use appropriate thread sealant or locking compound as required by the equipment manufacturer, and verify that the thread engagement depth meets the mounting hardware specification. Do not exceed the rated stroke or load capacity, as overloading can cause premature failure or equipment damage.
