Durable plastic drive pulley designed for DIY and educational builds. It features a 7.1mm outer diameter and a 1.97mm inner bore, which provides an ideal tight fit on 2mm shafts, such as those found on classic yellow or metal hobby DC Motors. The practical U-shaped groove is specially molded to accept common office rubber bands, small silicone belts, or O-rings, ensuring smooth and slip-free power transmission.

 

Reliable Power Transmission for your STEM Projects

Proper power transmission is the key to any successful robotics and DIY build. This small but practical plastic pulley allows you to transfer motion from your motor, easily altering the speed or torque of your mechanical system.

Key Features

  • Precision Fit: The 1.97mm inner bore guarantees a tight fit on 2mm shafts without slipping, preventing energy loss during rotation.
  • U-Groove Design: The groove is perfectly shaped to accommodate common rubber bands, string, or O-rings for seamless drive transfer.
  • Compact Build: Made from durable plastic material, it remains extremely lightweight so as not to overload small motors.

Frequently Asked Questions (Q&A)

Q: Does this fit small 3V-6V hobby DC Motors?
A: Yes, as long as you select the version with the 2mm inner bore, it fits perfectly onto the standard 2mm shafts found on most hobby DC motors (like the classic yellow gear motors).

Q: What kind of belt can I use?
A: The groove width (1.3mm) is designed to easily accept standard office rubber bands, durable string/twine, or specific miniature silicone drive belts.
