Description [Hide]
Pololu has a series of low-friction caster balls. This means it's got some pretty nice design points, and with a 3/8" plastic ball, it offers a nice, low-friction ride at a height of 0.4" to 0.6"
The kit features black ABS housing, a 3/8" diameter plastic roller, and two spacers (1/16" & 1/8" thick), and a pair of #2 nut/bolt sets.
And weighing only 1 gram, it's light!
