DAZZLEEX Synchronous Pulley Kit – Precision Timing Belt Drive Set

Upgrade your mechanical projects with this complete DAZZLEEX Timing Belt Pulley Set, featuring a matched 20-tooth and 48-tooth synchronous pulley pair with an 8mm bore. Precision-machined from high-grade aluminum alloy, this kit delivers smooth, low-noise synchronized transmission for 3D printers, CNC machine tools, plotters, stepper motors, and automatic feeding mechanisms. Everything you need for a quick, secure installation is included — pulleys, belt, and wrench. Made in China.

Key Features

Precision-Machined Teeth: Tightly meshed, regularly spaced teeth minimize slippage and transmission errors, ensuring accurate speed ratios and smooth, quiet operation.
Universal 8mm Bore: Standard inner bore fits most motor and drive shafts directly — no adapters needed. Secure, stable installation with the included wrench for fast assembly.
High-Tensile Synchronous Belt: The included 200mm circumference, 6mm wide belt offers exceptional toughness, wear resistance, and resistance to elongation for long-term continuous operation — reducing maintenance and extending system lifespan.
2.4:1 Speed Ratio (20T / 48T): The 20-tooth and 48-tooth gear combination provides a stable, precise speed ratio ideal for 3D printers, small CNC lathes, milling machines, drilling machines, and plotters.
Aluminum Alloy Construction: Lightweight yet durable high-precision machined aluminum alloy pulleys deliver reliable synchronized transmission across a wide range of mechanical equipment.

Frequently Asked Questions

Q: What types of equipment is this timing belt pulley set compatible with?

A: This synchronous pulley kit is designed for a wide range of mechanical transmission equipment, including 3D printers, small CNC machine tools, milling machines, drilling machines, gear machines, CNC lathes, plotters, and automatic feeding mechanisms. Any device using an 8mm shaft and requiring a 2mm pitch synchronous belt can utilize this kit.

Q: Does the 8mm bore fit my motor shaft directly?

A: Yes. The 8mm standard inner bore is designed to directly adapt to most motor and drive shafts without modification. The set includes a wrench for quick and secure tightening, making installation straightforward and efficient.

Q: What is the speed ratio provided by the 20-tooth and 48-tooth pulley combination?

A: The 20T and 48T pulley combination delivers a 2.4:1 speed ratio (48 ÷ 20 = 2.4), making it ideal for applications that require precise speed reduction and reliable synchronized power transmission.

Q: How durable is the synchronous belt included in the kit?

A: The included synchronous belt features high tensile strength and excellent wear resistance, engineered to resist deformation and elongation during long-term continuous operation. This helps reduce maintenance frequency and extends the overall lifespan of your transmission setup.
