Unique-Bargains 123A Wire Cap Connectors 10pcs 12T .5M 7mm OD 5mm TH 2mm ID

SKU CH-S4CX-BMMQ7 MPN 123A

Pack of 10 plastic gear connectors with 12 teeth and 0.5 modulus for DIY robotics and model projects

  • TypeCable Connectors
  • 10 pieces included for multiple DIY projects
  • 12-tooth design fits model 123A specifications
  • 5 modulus suits small motor applications
  • 7 mm outer diameter matches standard gear sizing
  • 2 mm hole diameter works with common shafts

Plastic Crown Gears for DIY Projects

This pack contains ten model 123A plastic crown gears with twelve teeth each. They are designed for science DIY projects such as RC model cars, electric robots and windmills. The gears also serve well for educational demonstrations of gear ratios and other small motor hobby tasks. Each gear is brand new and ready for immediate use.

Hobbyists and Educators Building Small Mechanisms

The gears suit builders who need a small quantity of lightweight plastic gears for low-torque experimental models. They are not intended for high-load drivetrains, continuous industrial duty or applications requiring metal gears. Buyers who need larger diameters, different tooth counts or higher strength materials should look at other gear ranges.

Ten Gears Provide Spares for Iterative Builds

With a 0.5 modulus, 7 mm outer diameter, 5 mm thickness and 2 mm bore, each gear fits small motor shafts common in hobby robotics. The ten-piece pack gives enough parts for multiple prototypes or replacements during testing. Headroom is limited to light-duty motion transfer; the plastic construction will strip under sustained heavy torque.

Questions about this item

What motor shaft diameter is needed for the 2 mm hole on these 123A gears?

The 123A gears have a 2 mm hole diameter, so they fit a 2 mm motor shaft directly.

Will these .5 modulus gears mesh with other .5 modulus gears I already own?

Yes, the .5 modulus matches other .5 modulus gears, and the 12 tooth count will engage correctly.

How can I verify the gears are the correct 123A model after opening the pack?

Count 12 teeth and check the 7 mm outer diameter and 5 mm thickness to confirm the 123A specification.
