Description
This steel pinion gear is designed to mesh with plastic spur gears, delivering durable, precise drive in small hobby gear trains. It features a 1/8″ bore, 48 pitch, and 25 teeth, and includes a set screw to secure it to a shaft. A 1/16″ Allen wrench (not included) fits the set screw for tightening.
Constructed from hard nickel-plated alloy steel, it resists wear and maintains smooth engagement with plastic spur gears. The tooth count is stamped on the gear for quick identification, and the 1/8″ bore supports common shaft sizes, making it a reliable upgrade or replacement in drive systems that pair with plastic spur gears.
