Unique-Bargains 112A 11-tooth 0.5 modulus wire cap connector 10 pcs

SKU CH-YH0D-4Y5DS MPN 112A

Pack of 10 plastic 11-tooth gears, 0.5 modulus, for DIY motor projects

  • TypeCable Connectors
  • 10-piece pack supports multiple DIY builds
  • 11-tooth 0.5 modulus gear fits small motor projects
  • 5 mm outer diameter suits compact assemblies
  • 2 mm bore matches common hobby shafts
  • New plastic construction resists wear in educational models

DIY Gear Components

This pack supplies ten model 112A plastic crown gears for hobby projects. Each gear has 11 teeth and a 0.5 modulus profile suited to small motor drives. The parts arrive new and ready for assembly in rc cars, robots or windmill models. They serve educators and makers demonstrating gear ratios in classroom or home workshops.

Precision Moulded Plastic

The gears measure 6.5 mm outer diameter with a 5 mm thickness and a 2 mm centre bore. Moulded plastic construction keeps weight low while maintaining consistent tooth form for smooth meshing. The 2 mm hole fits common micro motor shafts without modification. Ten pieces provide spares for iterative prototyping or multi-gear trains.

Upgrade From Improvised Parts

Builders who have been cutting gears from sheet stock or salvaging mismatched components gain repeatable 0.5 modulus geometry. The uniform tooth count ensures predictable speed reduction across identical modules. The jump is worthwhile when a project demands reliable meshing and consistent backlash for accurate motion control.

Questions about this item

What is the 0.5 modulus and 11-tooth count of the 112A gear?

The 0.5 modulus defines the tooth size and the 11-tooth count sets the gear ratio for small motor drives.

What are the 6.5 mm outer diameter and 2 mm hole diameter of the 112A gear?

The gear measures 6.5 mm across the teeth with a 2 mm bore for a matching motor shaft.

How are the 112A press-fit gears installed on a shaft?

Press the 2 mm bore onto the shaft until the 5 mm thick gear seats fully against the shoulder.
