Armature Bar - Liner (Steel)

The Armature Bar – Liner (Steel) is a core moving component in a coil tattoo machine, designed to create the quick, responsive motion needed for clean line work. As the coils energize, they pull the armature bar downward; when the circuit breaks, the springs snap it back up. That rapid cycle drives the needle bar and ultimately determines how the machine hits.

This liner armature bar is made from 1018 steel, chosen for its strong magnetic response and durability in coil machine setups. It measures 1.875″ overall length (1.5″ bar length with a 0.375″ nipple) and 3/8″ width, and is available in black oxide, nickel-plated, or raw steel finishes. Built in the USA by Lucky Supply MFG, it’s a dependable replacement or build component for artists tuning liner machines.
