The Plastic Double Sided Gear Rack 72 Teeth features a 144mm length, 9mm width, 10mm height, with 2mm tooth pitch, in durable yellow plastic. This Gear Rack stands out from the 50-tooth and 82-tooth racks lineup through its 2mm pitch — half the tooth spacing of the 4mm pitch variants — making it the finest-pitch and most positionally precise option in the rack family, requiring a matching 2mm pitch pinion gear for correct tooth engagement.
The 72 teeth plastic gear rack’s 2mm pitch means a 20-tooth pinion advances the carriage only 40mm per full revolution compared to 80mm per revolution on a 4mm pitch rack — this finer resolution halves the travel per step, giving twice the positional precision for the same motor movement, which is valuable in applications like camera focus racks, miniature CNC pen plotters, and compact robotic joints where controlled, small-increment positioning matters more than fast coarse travel. This double sided gear rack’s 9mm narrow width suits tight-clearance mechanisms where the wider 16mm or 20mm body of the larger rack variants would not physically fit.
this linear gear rack’s 144mm body gives approximately 130mm of usable carriage travel — the shortest range in the rack lineup — making it suited exclusively for compact short-stroke applications where full 144mm body length cannot extend further without a rack extension. Available from StemVolt, offering quality robotics parts and DIY kits at competitive prices.
