Rotary Tattoo Machine Bearing Part for The Beretta Silencer Liner Shader Parts (4.0mm)

This is a bearing part designed for rotary tattoo machines that use the armature bar drive. This will fit our Hildbrandt Silencer and Beretta rotary machines. This will also fit the 1st generation Stealth. Also known as a cam, cam wheel, motor bearing and flywheel. The size of the bearing affects the speed of the stroke and therefore a smaller bearing will result in a faster machine and a larger bearing will result in a slower machine. The 2mm bearing is more suitable for lining, 3mm for shading and 4mm for shading.
