Bearing Blaster

Created on 31 Oct 2018

Are you on a buggy team? Do your hands ache from cleaning bearings? Fear no more!

The Bearing Blaster cleans multiple ball bearings simultaneously. It spins and washes bearings with acetone, flushing out any loose particles or excess lubricant in the mechanism. It saves mechanics time and effort, while safely containing the mess.
