We can customize linear actuators according your required installed length when fully retracted and the stroke length that can be extended. For example, for a linear actuator with a stroke of 200mm, the installation length when fully retracted is generally 375mm. We can increase the installation length according to your installation requirements, such as increasing its installation length to 400mm, 450mm or 500mm. We can also customize linear actuators with stroke lengths in the range of 0-200mm according to your stroke length requirements, such as customized stroke lengths of 95mm, 125mm, 175mm and so on.
