Parker SC300M4 Male Button Shock Absorber M20 X 1.5

Product Description

The PARKER SC300M4 is a male button-style shock absorber designed to decelerate moving loads and dissipate kinetic energy in industrial automation and machine control applications. The unit features a stainless steel rod measuring 0.19 inches in diameter and a steel body with a black oxide finish. The outside diameter is 0.66 inches, overall length is 4.62 inches, and stroke length is 0.59 inches. The M20 x 1.5 thread mount allows for secure, direct installation into standard threaded bores. Maintenance technicians and machine builders working with pneumatic or motion control systems install this component as part of end-of-travel cushioning assemblies.

This shock absorber is suited for light-duty industrial applications where controlled deceleration of small actuators, slides, or moving tooling is required. The male button configuration is common in compact automation fixtures, pick-and-place equipment, and pneumatic cylinder end-stop applications. Operating temperature range spans 32 degrees F to 150 degrees F, making it appropriate for standard indoor manufacturing environments. The black oxide finish provides a degree of corrosion resistance for typical shop and factory floor conditions.

Key Features

• Male button absorber type for direct threaded installation in machine fixtures
• Stainless steel rod for corrosion resistance at the contact surface
• Steel body with black oxide finish for durability in industrial environments
• M20 x 1.5 thread size for compatibility with standard metric threaded mounts
• 0.59 inch stroke length suitable for light-duty end-of-travel cushioning
• Rated for operation from 32 degrees F to 150 degrees F

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial automation systems requiring a male button shock absorber with M20 x 1.5 threading and a 0.66 inch outside diameter.

Installation Notes

Installation is performed by qualified machine builders or maintenance technicians familiar with industrial motion control systems. Isolate all pneumatic pressure and electrical power to the machine before servicing end-stop or cushioning assemblies. Use appropriate metric tooling to torque the threaded body into the mounting fixture without overloading the rod or body. Verify stroke alignment with the moving load to prevent side-loading the rod during operation.
