H series is the most common linear module, with a traditional double linear guide rail and ball screw design. We use our own brand TPA's linear guide and ball screw by default, but you can choose the brand equipped with linear guide and ball screw according to your needs. Although most application models with small sizes and short strokes have been replaced by the KK series and the G series, the H series is still the most stable model under long strokes, heavy loads, and overhang conditions.
