What Parts Make Up a Tattoo Machine?

Rotary and coil machines move the needle differently, so each requires different tattoo machine parts. With both corded and electric options, rotary machines operate using an electric motor and cam system. Their motors vibrate less than coil machines, which helps maintain consistent speed. In addition to the motor, core rotary tattoo machine parts are the O-rings and drive bars. 


Rather than a motor, coil machines offer precise, strong, punchy movements because a mechanism lets electromagnetic coils propel the needle. Internally, there are more moving coil tattoo machine parts than rotary tattoo machine parts. Coil machines allow artists to customize speed, hit, and stroke by adjusting the coils and springs. Other coil tattoo machine parts that need maintenance are the frame, tube, and grip.

Common Replacement Parts and When to Swap Them

With regular maintenance, you can keep your trusted equipment working reliably. Important parts of a tattoo machine to replace are the cams, motors, cord holders, and O-rings. Tattoo artists should replace O-rings regularly (every one to two weeks) while cleaning.


For the motor and cams, pay attention to how your machine changes while you work. A new rotary machine feels smooth, but the cam will start to wear over time. If you notice inconsistencies or friction, swap out for a new cam. Over time, you may also notice reduced consistency from an aging motor. Fortunately, you can swap in a new motor instead of buying a new machine. To make motor replacement easy, refer to a tattoo machine parts diagram. 


After upgrading your equipment, keep your workstation organized with magnetic cord holders. 

Quick Tips for Maintaining Your Machine

Keep your Pro tattoo machine parts clean, stored properly and replaced in a timely manner. This ensures the safety and longevity of your machine. 

  • To clean your machine, disassemble it, wipe it down with 70% isopropyl alcohol wipes and lubricate it before reassembling. For coil machines, deep clean every few weeks by breaking it down and cleaning under the coils.  

  • Routinely check rotary tattoo machine and tattoo coil machine parts for wear. Keep springs, grommets, drive bars, O-rings, and connection pins in mind, and replace them regularly.

  • After cleaning, store the machine in a clean, dust-free location. 


When it's time to replace worn tattoo machine parts, shop Peak machine parts and replacement components at Ultimate Tattoo Supply.

Frequently Asked Questions

Which parts of a tattoo machine most commonly need replacing?

For rotary machines, replace O-rings, cams, drive bars, and connection pins regularly. With time, you may also need to upgrade to a new motor. For a coil machine, keep a consistent maintenance schedule for the frame, tube, grip, coils and springs. When disassembling a coil tattoo machine to clean the parts, watch for worn screws and replace them as needed. For easy disassembly, refer to a coil tattoo machine parts diagram. 

How often should you replace O-rings on a tattoo machine?

Update O-rings as part of your tattoo machine parts maintenance check. Replacing the O-rings every one to two weeks will ensure ideal working conditions for your machine. However, O-rings can break at any time, so always keep extras handy at your workstation as part of a tattoo machine parts kit. 

How do I choose a cam size for my tattoo machine?

The cam affects stroke size in rotary machines. The stroke changes based on the cam wheel's rotation length. By swapping cam wheels, you can adjust stroke length without changing machines. Shorter strokes are best for shading and blending, while longer strokes create bold lines. Choose the cam size based on the strokes you need, and swap it out as needed. 

How do you know when it is time to replace tattoo machine parts?

When cleaning, look for wear on the parts of a tattoo machine. Regularly swap out certain rotary tattoo machine parts like O-rings and tattoo coil machine parts like springs. Replace other parts, such as cams or the motor, when your machine doesn't run smoothly. 

Do Peak tattoo machine parts work for other brands?

Compatibility among Peak tattoo machine parts and other brands depends on the part type. Some parts, like replacement cams, are only compatible with specific machines. Other tattoo machine parts, such as the Peak Magnetic Cord Holder, can be used with any corded machine. To verify compatibility, each Peak tattoo machine part product page lists the compatible machines.
