Frequently Asked Questions

AI
Stainless steel offers superior strength and wear resistance for heavy-duty motion, while aluminum is preferred for lightweight applications where corrosion resistance is key but extreme load is not a factor.
The bore size must exactly match your motor or drive shaft diameter. Even a fraction of a millimeter difference can lead to slippage or the inability to mount the component securely.
Many use standard diameters like 8mm, but you must verify the total length and the tolerance grade to ensure the bearings slide smoothly without excessive play.
