These 624ZZ Radial Ball Bearings are small and lightweight yet highly efficient Bearings made for smooth radial motion. They offer a 4mm bore with a 13mm outer diameter and 5mm thickness, as is perfect for mounting motors or accessories onto Linear Shafts, leadscrews or other rod-like structures. These bearings are designed with high-strength metal alloys, with shielding on each side to keep the balls clean and rolling smoothly, resulting in a long lifespan of consistent smoothness and mechanical accuracy despite the relatively simple nature of the design.

Typical Applications for 624ZZ Radial Ball Bearings:

While many of our Radial Bearings are stocked for general purpose applications, we have stocked these 624ZZ bearings specifically for our Prusa i3 in-house 3D Printers, which uses two of these bearings as belt idlers. However, that doesn’t mean you can’t use them for other applications, and they can realistically be used for almost any use case requiring low-friction radial motion involving 4mm linear shafting or 13mm outer diameter mounting.
