10cm Large Plastic Pulley Wheel – 100mm Diameter x 20mm Width with 6mm Shaft Bore for Robotics, DIY Lifting Systems, and Science Projects

Product Description

The 10cm Large Plastic Pulley Wheel is a robust mechanical component designed for applications requiring significant torque transfer or high-displacement motion. Featuring a generous 100mm diameter and a 20mm width, this pulley is engineered to handle larger drive belts, ropes, or elastic bands compared to standard hobby pulleys. Its 6mm centre bore makes it perfectly compatible with high-torque DC geared motors and standard 6mm steel rods. At Robogears, we recommend this pulley for building heavy-duty conveyor systems, complex lifting mechanisms, and school science projects that demonstrate the mechanical advantage of pulley systems.

Detailed Key Features

• Significant Mechanical Advantage: The 100mm large diameter allows for substantial speed reduction or torque increase when paired with smaller motor-side pulleys.

• Precision 6mm Bore: Specifically sized for a secure fit on 6mm shafts, ensuring reliable power transmission without wobbling.

• Wide 20mm Profile: The 2cm width provides a stable track for wider belts or multi-strand ropes, preventing them from slipping off during operation.

• Durable Plastic Construction: Moulded from high-strength plastic that offers excellent wear resistance while remaining lightweight to reduce rotational inertia.

• Versatile Mounting: Can be used as a primary drive pulley on a motor or as a free-spinning idler wheel in a complex mechanical linkage.

All Technical Details

• Mechanical Design: Single-groove profile optimised for round or flat-bottomed belts.

• Surface Finish: Low-friction groove surface to minimise belt wear and heat buildup during continuous use.

• Load Handling: Designed to support moderate loads typical in STEM robotics and tabletop automation projects.

• Stability: Precision moulded to maintain balance at various rotational speeds.
