Acetal MOD 0.8 Gear Rack (118 Tooth, 41 Hole)

This MOD 0.8 pitch, 118 tooth gear rack is the same one used in the goBILDA® Servo-Driven Gear Rack Kits. The repeating 4mm holes make it easy to fasten to goBILDA® components to build a linear motion assembly. Because it is acetal, it is low-friction and has impressive wear characteristics.
