Stainless Steel Motion Axle Rods

This pack contains five stainless steel circular rods measuring 400mm in length and 3mm in diameter. They serve as motion axles for mechanical transmission projects in hardware and mold applications. The silver tone finish suits general engineering and hobbyist builds.

Material Properties in Use

Stainless steel construction provides inherent corrosion resistance for reliable operation in standard environments. The solid bar design ensures dimensional stability under normal rotational loads without added cooling requirements. Net weight of 80g for the full set keeps inertia low for responsive motion.

Five Rods for Spares and Builds

The five-piece bundle supplies enough shafts for multi-axis assemblies or replacement stock. No additional hardware or software is included with the rods. Builders must source collars, bearings or couplings separately to complete a drivetrain.

Questions about this item

How do I install the 400mm stainless steel rod into a mechanical transmission assembly?

Cut or file the rod to the exact length required, then press-fit or secure it with set screws in the drilled hubs; the common mistake is skipping the deburring step, which leaves metal shavings that jam bearings.

What maintenance or replacement will the 5-piece rod set need over time?

Inspect each 3mm diameter rod periodically for surface scoring or corrosion; replace any piece that shows pitting or bend, as stainless steel cannot be economically re-hardened once damaged.

What is the first limit that appears when the rod runs continuously at high speed?

The 3mm diameter reaches its critical whirl speed first, causing lateral vibration that degrades positional accuracy before the material itself yields.
