Parker MC4550-2 Male Button Shock Absorber 1.91 in Stroke

Product Description

The PARKER MC4550-2 is a male button shock absorber designed to decelerate moving loads and dissipate kinetic energy in industrial automation and motion control applications. The unit features a 0.5 inch rod diameter, a 1.75 inch outside diameter, and a 1.91 inch stroke length, making it suited for moderate-force deceleration tasks. The 1-3/4-12 threaded body allows direct mounting into compatible actuator housings or machine frames. Overall length is 7.69 inches. Licensed mechanical technicians and automation specialists are the typical installers on factory and machine-tool environments.

This shock absorber is applied in industrial machinery, assembly automation, conveyor end stops, and pneumatic or hydraulic actuator systems where controlled deceleration is required. The male button style end fitting allows the absorber to contact moving components directly without additional hardware. Typical installations include end-of-travel cushioning on linear slides, robotic work cells, and material handling equipment where repetitive cycle loads must be managed consistently.

Key Features

• Male button absorber type for direct-contact deceleration without additional end fittings
• 0.5 inch rod diameter provides a robust working surface for moderate impact loads
• 1.91 inch stroke length delivers controlled energy absorption over a usable travel range
• 1-3/4-12 threaded body for secure, direct mounting into machine frames or actuator bores
• 1.75 inch outside diameter suits standard mounting block and bracket configurations
• 7.69 inch overall length supports installation in applications requiring adequate clearance

Compatibility

Designed as an OEM-style replacement or direct-fit shock absorber for industrial automation equipment accepting a 1-3/4-12 threaded male button style unit with a 1.75 inch outside diameter and 1.91 inch stroke.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with industrial motion control equipment. De-energize and lock out all pneumatic, hydraulic, and electrical energy sources before servicing any actuator or end-stop assembly. Thread engagement should follow standard machine thread practices to ensure secure retention without cross-threading. Verify stroke alignment with the intended load path to prevent side-loading the rod during operation.
