Reely Polyacetal Rack Gear Module 1.0 250 x 9 x 9 mm (ZH10250HF)

This Reely rack gear is machined from polyacetal (POM), a self-lubricating engineering plastic that offers high mechanical strength, excellent wear resistance, and a low coefficient of friction. Unlike metal racks, it runs quietly and resists corrosion, making it well suited for lightweight linear motion systems, robotics, and model building where precision and smooth operation matter.

Highlights

• Module 1.0 straight-cut tooth profile for compatibility with standard module 1.0 pinions
• Polyacetal (POM) construction provides high dimensional stability and good fatigue resistance
• Self-lubricating properties reduce maintenance and extend service life
• Good chemical resistance for use in demanding environments
• Length 250 mm, width 9 mm, height 9 mm

In daily use

The rack's natural POM colour blends unobtrusively into most mechanical assemblies. It can be mounted using adhesives or screws (not included) to suit your specific linear drive design. With continuous linear gearing, it delivers consistent tooth engagement along its full length, ensuring smooth travel for carriages, gantries, or automated fixtures.
