Description: Rollin' rollin' rollin', you can now roll around smooth as silk with these radial bearings. Often referred to as "skate bearings" They're good for supporting a rotating rod or as a wheel hub. However, these are higher quality, meant for continuous use so they'll last longer than cheap skateboard bearings. Ideal for use in your CNC project or robot. 

Standard 624ZZ sizing, which means they're 13mm outer diameter, 4mm inner diameter, and 5mm wide. They're pre-greased and shielded so they wont get clogged easily. Comes in a set of 4!
