Parker MC4550M3 Male Button Shock Absorber M45 X 1.5

Product Description

The PARKER MC4550M3 is a male button style 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 provides controlled energy absorption to reduce impact forces on machinery components. The M45 x 1.5 threaded body allows for direct mounting into compatible fixtures and brackets. Overall length measures 7.69 inches. Weighing 2.69 pounds, the MC4550M3 is suited for moderate-duty linear deceleration tasks where repeatability and consistent stopping force are required. Installation is typically performed by industrial maintenance technicians or automation system integrators.

The MC4550M3 is intended for use in industrial machinery, automated assembly lines, conveyor systems, and robotic end-of-travel stop applications. The male button contact face transmits load force directly into the absorber body, making it well suited for applications where a plunger or fixed-mount contact point is needed. This unit fits residential and light commercial automation setups as well as heavier industrial environments where a compact, threaded shock absorber is required.

Key Features

• Male button absorber type provides a direct contact face for end-of-travel load deceleration
• 0.5 inch rod diameter with 1.91 inch stroke length for controlled cushioning travel
• 1.75 inch outside diameter with M45 x 1.5 threaded body for secure fixture mounting
• 7.69 inch overall length suits installations requiring a longer body profile
• 2.69 pound unit weight compatible with standard industrial mounting hardware

Compatibility

Designed as an OEM-style replacement or direct-fit shock absorber for industrial automation and motion control systems requiring an M45 x 1.5 threaded male button shock absorber with a 1.91 inch stroke and 1.75 inch outside diameter.

Installation Notes

Installation should be performed by a qualified industrial maintenance technician or automation engineer. De-energize all pneumatic, hydraulic, and electrical systems and relieve residual pressure before servicing or replacing shock absorbers. Thread engagement should be sufficient to fully seat the absorber body without over-extension; do not exceed the rated stroke during operation. Verify alignment of the contact face with the load to prevent side-loading the rod.
