Parker MA4550 Male Button Shock Absorber 1.91 in Stroke

Product Description

The PARKER MA4550 is a male button shock absorber designed to decelerate and cushion moving loads in industrial automation and motion control applications. With a 0.5-inch rod diameter, 1.75-inch outside diameter, and a 1.91-inch stroke length, this unit is built to absorb kinetic energy and reduce impact forces at the end of travel. The 1-3/4-12 thread size allows for secure, direct mounting into compatible fixtures. The steel rod and steel body construction, finished in black oxide, deliver corrosion resistance and durability in demanding service environments. Overall length is 7.69 inches. Licensed millwrights, maintenance technicians, and automation engineers are the typical installers.

This shock absorber is suited for use in manufacturing, assembly line, and industrial machinery applications where repetitive end-of-stroke cushioning is required. The male button configuration makes it appropriate for installations where the absorber contacts a moving carriage or actuator at the end of its travel path. It operates reliably across a temperature range of 10 degrees F to 150 degrees F, making it suitable for both indoor and light cold-environment installations. It is sold individually and ships as a single unit per package.

Installation Notes

Installation is typically performed by qualified maintenance technicians or automation engineers. Depressurize and de-energize all associated pneumatic, hydraulic, and electrical systems before beginning installation or removal. Ensure thread engagement meets the fixture manufacturer's minimum requirement and that the absorber is properly torqued per the equipment OEM specification. Do not exceed the rated stroke or operating temperature limits during service.
