Sprockets and Chain


Chain - Delrin (0.25" x 12")
These plastic chains come in 1ft lengths preassembled with 48 individual and snapable bits, they have a tensile strength of 55 lbs, and 0.25” tooth spacing. Actobotics is a robotics building system based around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to the two standardized hole patterns, nearly all Actobotics components can be intuitively connected together. The wide range of components makes building complex electromechanical prototypes or finished projects a reality. Features: Length - 1 foot Documents: Product Page (615150) ..

Cable Carrier - 10x15mm (0.5m Length)
No, this isn’t a tank tread, this is a 0.5m long Cable Carrier with 10x15mm bits composing its main body and two screw fasteners at each end for efficient mounting. Sometimes called a “drag chain,” each carrier can be used in projects with a large number of moving parts to protect internally installed cables, pipes, or tubes so they can be bent and moved while remaining protected. Cable carriers can most commonly been found in 3D printers and CNC machines but they can be used in any situation where you need cables or tubes to bend without risk of them being damaged or wearing out prematurely. ..
