Complete guide: Inkmachines nr. 41B - X2 Eccenter assy (Preset SHORT 2.6MM) - 1pcs
This is the original Ink Machines replacement part that sets the needle stroke on Dragonfly rotary machines. It comes pre-set from the factory on the short version, 2.6 mm — the stroke, i.e., the distance the needle travels, is the parameter that most influences the machine's style and behavior. The SHORT eccentric assembly is oriented towards fine lines, details, dotwork, and micro-realism, where you want a shallow and controlled penetration. Being an internal mechanical component, replacement requires some skill and the right tools.
How to use
- Make sure the machine is turned off and prepare the tools: the ring pliers No. 55 (mandatory for changing this assembly) and the smallest hex key, 0.9 mm.
- Using the ring pliers No. 55, remove the retaining ring and push out the connecting pin to free the old assembly.
- Loosen the eccentric on the motor shaft with the 0.9 mm hex key. Note: on the standard eccentric there are two screws — use only the one for the motor shaft, not the one for the bearing shaft.
- Mount the new X2 assembly on the motor shaft and make sure the screw reaches the flat part of the shaft, then tighten it well.
- Check if the connecting rod aligns correctly with the groove in the piston — this is important; if it doesn't align, the machine will not function properly.
- Align the upper bearing with the hole in the piston, insert the connecting pin, and put the retaining ring back in place.
- Briefly start the machine and check its operation; if the connecting rod does not align, you may need to readjust the motor position or consult the manual or repair service.
- Optionally, if you want an intermediate value, the stroke can be adjusted from 2.6 to 4.5 mm with the precision tool kit No. 90.
Tips from us
- Choose the SHORT 2.6 mm version when working on fine and ultra-fine lines, dotwork, micro-realism, intricate details, or sensitive areas — the short stroke gives you the best control over depth.
- If you also do fills or color packing, keep a STANDARD 3.7 mm or LONG 4.5 mm assembly handy; the system allows you to change the stroke without buying another machine.
- With the precision tool kit No. 90, you can fine-tune the stroke between 2.6 and 4.5 mm if you want intermediate values, not just the factory preset.
- Handle the retaining rings only with the No. 55 pliers — they are small and easy to lose or deform; it's useful to have a spare ring.
- After assembly, run the machine for a few seconds without a needle to confirm smooth and aligned operation before working on skin.
- When reordering the part, note the reference no. 41B and model 375580 to ensure you receive the exact correct X2 assembly.
Warning: This is an internal mechanical replacement part for professional rotary machines, not a consumable. Perform the installation with the machine turned off and follow the manufacturer's manual: tighten only the screw for the motor shaft, on the flat part of the shaft, and check the alignment of the connecting rod with the piston. Incorrect installation (misaligned connecting rod or improperly tightened screw) can lead to malfunction. If you cannot achieve correct alignment, consult the manual or send the machine for service. The component does not come into contact with the skin, but continue to follow your usual hygiene and barrier protection protocol for the parts of the machine that touch the skin or the client.
Frequently asked questions
For which styles is the SHORT 2.6 mm stroke recommended?▾
The short 2.6 mm stroke is oriented towards fine and ultra-fine lines, dotwork, micro-realism, intricate details, and working on sensitive areas. The shallower and controlled penetration gives you maximum precision where you need finesse.
Does it fit my machine?▾
It is the X2 eccentric assembly (reference no. 41B), and the manufacturer's description says it fits Dragonfly machines. Verify that you have a Dragonfly machine and use reference no. 41B / model 375580 to ensure it's the correct part. If you have doubts about the exact version of your machine, ask us before ordering.
What tools do I need to install it?▾
You need the ring pliers No. 55 to remove the ring and connecting pin, and the smallest hex key, 0.9 mm, to loosen the eccentric on the motor shaft. Optionally, the precision tool kit No. 90 allows you to fine-tune the stroke.
Can I change the stroke to another value?▾
Yes. The assembly comes pre-set on SHORT 2.6 mm, but it can be adjusted with the precision tool kit No. 90 between 2.6 and 4.5 mm. Additionally, you can completely switch to the STANDARD 3.7 mm or LONG 4.5 mm versions by replacing the eccentric assembly, depending on the style of the session.
Is it suitable for large fills?▾
It is not the ideal choice for large fills or intensive color packing, because the shallower penetration requires more passes for saturation. For fills, the STANDARD 3.7 mm or LONG 4.5 mm versions are more suitable; SHORT excels at details and lines.
How do I maintain and sanitize the part?▾
Being an internal component, it does not come into contact with the skin. Keep it clean and follow the manufacturer's maintenance recommendations for the machine's mechanism. For parts that touch the skin or the client, continue to apply your usual sterilization and barrier protection protocol.

Frequently Asked Questions What tattoo styles is the 2.6mm stroke recommended for? The SHORT 2.6mm stroke is ideal for: fine and ultra-fine lines, dotwork, micro-realism, work on sensitive areas (face, fingers, neck), intricate details, and any style requiring controlled shallow penetration. It offers maximum precision and minimal skin trauma. Can I change the eccentric from SHORT to STANDARD or LONG? Yes, this is one of the Dragonfly X2's greatest advantages - the ability to change stroke length by replacing the eccentric assembly. You can switch from 2.6mm (SHORT) to 3.7mm (STANDARD) or 4.5mm (LONG) based on session needs. The change requires partial machine disassembly. How much does the SHORT 2.6mm eccentric cost? The X2 eccentric assembly SHORT 2.6mm InkMachines no. 41B is available at approximately 38 EUR. The same price applies to STANDARD and LONG variants. Investing in multiple eccentrics allows adapting the machine to any tattoo style without purchasing separate machines. What practical difference does 2.6mm stroke make versus 3.7mm? The 2.6mm stroke penetrates less deeply and more delicately, ideal for fine lines and sensitive areas. The 3.7mm stroke offers moderate penetration, suitable for most general work. In practice, the 1.1mm difference is significantly felt in depth control and needle behavior upon skin contact. Is the SHORT 2.6mm eccentric suitable for fills? The 2.6mm stroke is not ideal for large fills or intensive color packing as the shallower penetration requires more passes for saturation. For fills, the STANDARD 3.7mm or LONG 4.5mm eccentric is more suitable. The SHORT stroke excels at details and lines, not extensive fills. How long does changing the eccentric take? Changing the eccentric assembly usually takes between 15 and 30 minutes, depending on the artist's experience with the Dragonfly X2 machine. The process involves partial machine disassembly, removing the old eccentric, installing the new one, and verifying operation. With practice, the operation becomes faster. Is the SHORT eccentric quieter than LONG? Generally, the shorter stroke produces slightly less noise and vibration because the movement amplitude is smaller. The difference is not dramatic but can be perceptible. All eccentric variants are designed for quiet operation in the Dragonfly X2 machine. Which eccentric do you recommend for beginners? For beginners, we recommend the STANDARD 3.7mm eccentric which offers the best balance between versatility and performance. Once the artist develops their style and preferences, they can add the SHORT 2.6mm eccentric for fine work or LONG 4.5mm for fills. Progressively, all three become essential. Is the eccentric compatible with the Stingray X2? The eccentric assembly no. 41B is designed for the Dragonfly X2 machine. The Stingray X2 has its own eccentric system with different specifications. Verify compatibility before purchase if you have another InkMachines model. Do not assume interchangeability between models. Is it worth having all three eccentrics? Yes, for a versatile professional artist, having all three eccentrics (2.6mm, 3.7mm, 4.5mm) transforms the Dragonfly X2 into a complete machine capable of covering any tattoo style. The total investment of approximately 114 EUR for all three is much less than purchasing separate machines.
