ABEC1 - Grade 5 ceramic sealed bearings.

Ceramic bearings are lighter, harder, more spherical, longer lasting, and have less rolling resistance than steel bearings. Wondering what bearings you need to replace your existing balls? You have a couple of choices: a) disassemble your system and use a micrometer on the bearing. b) give your product manufacturer a call or email asking them for bearing sizes.

All dimensions are in inches.
