linear bearing 12 mm

linear bearing for shaft 12 mm. Used balls of pematic weapons 4,5 mm. For an epiploon the rubber ring 12 * 17 * 3 mm was used. without rings, he skates under his weight and has an extremely small backlash. if necessary, you can change the size of the body in 4.5 mm steps. do not forget to lubricate the product)
in my opinion this is a very good thing
The sharp corners have been left especially for you to change it for your needs
