Reely polyasetaali hammaspyörä moduuli 0,5, 25 hammasta, 4 mm poraus (SH0525HF)

Precision motion systems often fail because of gear wear, friction, or dimensional mismatch. This Reely spur gear solves those problems with a polyacetal (POM) body that offers low friction and high wear resistance, ensuring smooth, reliable operation in model building, robotics, and precision mechanics.

Who is it for

Model builders, robotics enthusiasts, and engineers who need a durable, precise gear for module 0.5 drivetrains. It is ideal for applications where a 4 mm shaft is used and 25 teeth are required.

Main features

• Material: Polyacetal (POM) – low friction, high wear resistance
• Module: 0.5
• Number of teeth: 25
• Bore diameter: 4 mm
• Tooth profile: Involute, 20° pressure angle

Specifications
