The most common problem affecting actuator movement is mechanical jamming caused by core component wear and impurity intrusion, accounting for more than 60% of all actuator movement failures.
Specifically, this type of problem is particularly prominent in complex industrial environments such as those with dust, high temperatures, and corrosive media: for example, dust in the production environment can invade the interior of the actuator, embed in the sealing lip and accumulate in the guide sleeve, accelerating the wear of sealing components while causing actuator movement jamming and positioning failure; high-temperature environments may also be accompanied by issues such as spring elastic attenuation, further affecting the normal operation of the actuator. In addition, internal component aging (such as gear tooth breakage and bearing damage) and assembly problems (such as loose wiring) are also important inducing factors, but the core remains mechanical jamming caused by "component wear + impurity intrusion" as the most common.
