Steel Cam 4mm Std X2 (part no. 84) from Ink Machines is the stainless steel cam that converts the motor's rotation into the linear stroke of the needle bar on X2 generation rotary machines. With a 4mm stroke and Standard profile, it represents the longest and most aggressive stroke in the InkMachines range — a powerful, decisive hit. It is aimed at experienced artists working with bold lining, dense packing, and thick skin who want to tune their machine for maximum power.
What does a cam actually do on a rotary tattoo machine?▾
The cam (eccentric) converts the motor's rotational motion into the linear up-and-down movement of the needle bar. The stroke length — here 4mm — determines how far the needle travels: a longer stroke means a stronger hit, suitable for lining and packing, while a shorter stroke gives a gentler hit, good for shading and color. By changing the cam, you adjust your machine for different techniques.
Which machines does this cam fit?▾
It is specified for the X2 generation of InkMachines (e.g., Stingray X2 and Dragonfly X2) and mounts on the standard cam bearing (part no. 67). It does not work on the old Stingray model, which requires a more powerful motor. Always check compatibility with your exact machine version on tatuat.ro before ordering.
Why a steel cam instead of the standard material?▾
Steel is denser and heavier than the material of standard InkMachines cams. The extra mass increases inertia in the stroke, so the needle hits the skin with greater force. This is an advantage for penetrating thick skin, dense ink deposition, and bold lining where you want deep, saturated lines in one pass.
What styles is the 4mm cam recommended for?▾
It is suitable for American traditional and neo-traditional (thick, bold lines), packing on large areas, color packing for maximum saturation, and work on thick skin (back, shoulders, thighs), where shorter stroke cams do not provide enough penetration.
Does the steel cam put more strain on the motor?▾
Yes. The greater mass requires more energy from the motor to maintain speed, which is why it is specified for the X2 model, designed for these forces. On a machine with an undersized motor, you may experience speed loss under load, excessive heating, and accelerated wear.
How do I maintain the cam and the machine?▾
The cam is an internal part, so it does not come into direct contact with the skin, but it remains part of a tool used in an environment that must be kept clean. Mount and dismount it with clean hands on a disinfected surface, periodically check the fixation and free movement of the needle bar, and during work, protect the machine with barrier films/sleeves. Follow the manufacturer's instructions for maintaining your InkMachines machine.
