The 90T Blue timing pulley in a 4-pack from Makeblock is a precisely manufactured component made of anodized aluminum, ideal for various robotics and technology projects. With 90 teeth and an outer diameter of 58.21 mm, this timing pulley is specifically designed for MXL timing belts. Its open design with star-shaped bracing ensures an optimal balance between stability and weight savings. The central hole of 8 mm allows for easy mounting on compatible shafts, with an additional flange recommended for 4 mm or 8 mm shafts. The twelve side-mounted, slightly opened 4.2 mm mounting holes on a bolt circle provide versatile fastening options, making it an excellent choice for modular constructions. This timing pulley is part of the modular Makeblock system, which supports creative building projects in STEM education and allows for easy integration with other Makeblock components.
