The key components of motorized linear stages are transmit screw, lead screw, organism material, processing precision as well as overall adjustment level, which have great influence to the quality of motorized linear stages. Transmit screws mostly use ball screw, rubbing leadscrew and trapezoidal leadscrew. Ball screw rod and nut may easily realize rolling transmission, steady movement, high efficiency and speedy course through steel balls. Slipping transmission occurs between screw rod and nut of rubbing leadscrew and trapezoidal leadscrew. Rubbing leadscrew may use slight lead to enhance system resolution. Trapezoidal leadscrew with large transmit moment may realize self-locking specially for better effect when it uses as a vertical axis (high bearing, outage self-locking).

Lead screws have great influence to load bearing, straight movement, travel range of motorized linear stages. At present commonly used lead screw patterns are mainly cross-roller lead screw, linear slide lead screw, linear bearing lead screw and support linear bearing lead screw.

Organism material and processing precision have certain influence to the quality of motorized linear stages. Generally we use stainless steel and aluminum material. Organism processing equipment and technique are crucial to guarantee organism processing precision. Overall adjustment must have matched working equipment and detection instrument as its technological level also has influence to the quality of motorized linear stages. Normal use and maintain of motorized linear stages are quite important. Long-term overload movement and too high or too low environment temperature will affect motorized positioning precision, even worse will cause motorized linear stages to be unable to work. Upper rigid cover must be installed in dusty place. Lubricating fat or oil chosen according to screw rod, lead screw and working condition must be regularly complemented.
