A long-stroke pneumatic cylinder is a linear actuator designed to deliver extended travel distances—typically exceeding 1000mm—while maintaining compact dimensions and reliable performance. Unlike conventional rod cylinders that grow proportionally with stroke length, long-stroke solutions like rodless cylinders offer space-efficient alternatives for applications requiring significant linear displacement.

Stop tubes are critical internal components that prevent piston collision with cylinder end caps by providing controlled deceleration space, absorbing kinetic energy, and maintaining proper cushioning air flow in long-stroke pneumatic cylinders exceeding 24 inches. 

Cylinder drift caused by internal seal bypass can be systematically analyzed through pressure decay testing, visual leak detection methods, and performance monitoring to identify worn piston seals, damaged cylinder bores, or contaminated sealing surfaces that compromise holding force.

Rodless cylinder dust bands function as engineered sealing barriers that prevent contaminants from entering the cylinder bore through precise lip design, material selection, and pressure differential management, extending cylinder life by up to 300% in harsh environments.

External shock absorbers for cylinder applications require precise sizing based on kinetic energy calculations, deceleration distance requirements, and load characteristics to provide controlled energy dissipation and prevent damaging end-of-stroke impacts while maintaining optimal cycle times.
