Reely ingranaggio cilindrico in poliossimetilene modulo 1,0, 25 denti, foro 6 mm (SH1025HF)

Precision motion in model building and robotics demands gears that run quietly, resist wear, and keep their shape under load. This Reely spur gear in polyacetal (POM) delivers that with a module of 1.0 and 25 teeth, offering a pitch diameter of 25 mm and an outside diameter of 27 mm. The 6 mm bore fits common shafts, while the involute tooth profile with a 20° pressure angle ensures smooth meshing with compatible gears.

Who is it for

Model builders, robotics enthusiasts, and makers who need a reliable, low-friction gear for light mechanical drives. It suits custom transmissions, servo linkages, and small automation projects where metal gears would add unnecessary weight or noise.

Main features

• Material: Polyacetal (POM) – low friction, high wear resistance, good dimensional stability.
• Module 1.0, 25 teeth – pitch diameter 25 mm, outside diameter 27 mm.
• Bore diameter 6 mm – fits standard shafts.
• Involute tooth profile, 20° pressure angle – smooth, efficient power transfer.
