688ZZ Ball Bearing (8x16x5)
Measuring 8x16x5mm, these can be pretty handy. They suit an 8mm shaft and any of our full-size wheels, or could be used as a support bearing on an 8mm leadscrew.
These bearings are made of quality chrome steel, which ensures they are durable and long lasting. They are also double shielded (shielded on each side), in order to keep dust and other particulates out.
