Complete guide: Inkmachines nr. 41B - X2 Eccenter assy (Preset LONG 4.5MM) - 1pcs
This eccentric assembly (original part no. 41B, X2 variant) is the component that converts the motor's rotation into the up-and-down movement of the needle, on InkMachines Dragonfly rotary machines. It comes preset to a long stroke of 4.5 mm, designed for artists who seek power in filling and intense color saturation. Being a replacement part, it allows you to reconfigure the machine you already have without buying a new device.
How to use
- Prepare the necessary tools: ring pliers No. 55 (mandatory for replacing this assembly) and the smallest 0.9 mm hex key. Also have the precision tool set No. 90 on hand if you wish to adjust the stroke later.
- With the machine turned off and disconnected, use the ring pliers to remove the retaining ring, then push out the connecting pin.
- Loosen the old eccentric from the motor shaft using the 0.9 mm hex key. Caution: on the standard eccentric there are two screws — one for the motor shaft and one for the bearing shaft; use ONLY the one for the motor shaft.
- Mount the new assembly 41B onto the motor shaft. Make sure the screw reaches the flat part of the shaft and tighten it well.
- Check that the connecting rod aligns correctly with the groove in the piston. This step is important: if it does not align correctly, the machine will not function properly and you may need to readjust the motor position.
- Align the upper bearing with the hole in the piston, insert the connecting pin, and put the ring back in place with the pliers.
- Optionally, with the precision tool set No. 90, you can adjust the stroke between 2.6 and 4.5 mm, depending on the work you have to do.
- Run the machine for a few seconds and check for smooth operation before starting an actual session.
Tips from us
- The 4.5 mm LONG stroke is for intensive color packing, dense and uniform fills, traditional bold and neo-traditional — i.e., work that requires deeper penetration and maximum ink saturation.
- Do not use 4.5 mm for fine lines: too deep penetration can cause blowouts. For lining, shorter strokes (2.6 mm or 3.7 mm) are more suitable.
- If you work a lot on different styles, the InkMachines idea is to have multiple strokes and switch them — a single machine practically becomes multiple tools.
- The longer stroke produces slightly more noise and vibration than the short one, because the amplitude of movement is greater — this is normal, not a defect.
- Adapt the speed and voltage to the longer stroke; for delicate shading you will need more control than on a medium stroke.
- Keep the small parts (retaining ring, connecting pin) organized on a clean surface during assembly — they get lost very easily.
Warning: Perform the replacement only with the machine turned off and disconnected. Do not force or overtighten the screws — use the correct hex key (0.9 mm) and the proper screw for the motor shaft. Check the alignment of the connecting rod with the piston before running the machine; incorrect installation can damage the mechanism. Although this part is internal and does not directly touch the skin, the machine remains equipment that works in a bloodborne environment: after reassembly, protect the machine body with a disposable film/barrier during tattooing and keep the components clean.
Frequently asked questions
What is the 4.5 mm LONG stroke ideal for?▾
It is designed for deep penetration and maximum ink saturation: intensive color packing, dense and uniform fills, traditional bold, neo-traditional, and work on tougher skin areas. The longer stroke covers more surface with each movement, thus reducing the number of passes for filling.
Can I use the 4.5 mm stroke for fine lines?▾
It is not recommended for fine lines. Deeper penetration can lead to blowouts and blurry lines. Shorter strokes (2.6 mm or 3.7 mm) are more suitable for lining. Each stroke has its optimal range of use.
Which machines is this assembly compatible with?▾
It is the X2 eccentric assembly (original part no. 41B) for InkMachines Dragonfly rotary machines, according to the manufacturer's description. It is an original replacement part, one piece. If you have doubts about your exact model, check the part number (41B) and the name in your machine's manual before ordering.
What tools do I need to install it?▾
You need ring pliers No. 55 to remove and put back the retaining ring, and the smallest 0.9 mm hex key for the screw on the motor shaft. For subsequent stroke adjustment, you need the precision tool set No. 90.
Can I adjust the stroke after installing it?▾
Yes. Although it comes preset to 4.5 mm (LONG), the assembly can be adjusted with the precision tool set No. 90 in the range of 2.6 - 4.5 mm, depending on the technique you want to use.
How do I maintain the assembly and the machine after installation?▾
Perform any intervention with the machine turned off and disconnected, on a clean surface. Do not overtighten the screws. Periodically check the alignment of the connecting rod with the piston and smooth operation. During tattooing, cover the machine with a disposable film/barrier and keep the components clean and dry between sessions.
Product description
Inkmachines nr. 41B - X2 Eccenter assy (Preset LONG 4.5MM) Fits all Dragonfly machines. Pre-set to Long stroke 4.5mm Can also be adjusted with the No.90 Precision tool kit From 2.6 - 4.5mm Note that you will also need the No. 55 - Circlip pliers to replace this assembly. Hint! Use the Circlip Pliers to remove the Circlip and push out the Connecting pin. Loosen the excenter from the motor shaft with the smallest allen key 0.9mm. There are two screws on the standard excenter, one for the motor shaft and one for the bearing shaft. You only need to use the one for the motor shaft. Install the new assembly on the motor shaft and make sure that the screw ends up on the flat part of the shaft and tighten it securely. Check that the Connecting rod aligns properly with the groove in the Piston. This is important, if it does not align correctly it will not run properly and you might have to readjust the location of the motor. In that case please refer to the manual or send for service. If ok align the upper bearing with the hole in the piston and insert the Connecting pin and install the Circlip.

Frequently Asked Questions What is the LONG 4.5mm stroke ideal for? The LONG 4.5mm stroke is ideal for: intensive color packing, dense and uniform fills, traditional bold style, neo-traditional, work on areas with resistant skin, and any technique requiring deep penetration and maximum ink saturation. It is the preferred eccentric for intensive filling sessions. Is the 4.5mm stroke too long for lines? Yes, the 4.5mm stroke is not recommended for fine lines as deeper penetration can cause blow-outs and blurry lines. For lining, the SHORT 2.6mm or STANDARD 3.7mm eccentric are much more suitable. Each eccentric has its optimal use domain. Does the LONG stroke produce more noise? The longer stroke produces slightly more noise and vibration than the short stroke, as the movement amplitude is larger. The difference is minimal due to InkMachines precision design but can be perceptible. All variants are designed for quiet operation within the context of their performance. Can I use the LONG stroke for delicate shading? The LONG stroke can be used for shading but requires more control and experience to achieve delicate gradients. Speed and technique must be adapted to compensate for deeper penetration. For delicate shading, the STANDARD 3.7mm eccentric is usually a safer choice. How much does the LONG 4.5mm eccentric cost? The X2 eccentric assembly LONG 4.5mm InkMachines no. 41B is available at approximately 38 EUR, the same price as SHORT and STANDARD variants. The investment transforms the Dragonfly X2 into a powerful filling machine without purchasing separate equipment. How do I change the eccentric from STANDARD to LONG? The change involves partial disassembly of the Dragonfly X2 machine to access the eccentric compartment, removing the STANDARD assembly and installing the LONG one. The process takes 15-30 minutes. Consult the InkMachines guide for detailed step-by-step instructions. Does the LONG eccentric wear the machine faster? The longer stroke generates slightly larger forces in the drive mechanism, which theoretically can marginally accelerate wear. In practice, the difference is insignificant due to material quality and the robust Dragonfly X2 design. Regular maintenance is more important than the eccentric variant used. What power supply voltage do you recommend for the LONG stroke? The LONG stroke usually requires slightly higher voltage than the SHORT stroke to compensate for increased resistance and maintain optimal performance. The exact setting depends on cartridge type, work style, and personal preferences. Start at medium voltage and progressively adjust based on results. Is the LONG eccentric the most popular? Popularity varies depending on artists' predominant style. The STANDARD 3.7mm eccentric is the most versatile and popular for general use. LONG 4.5mm is preferred by artists specializing in traditional, neo-traditional, and intensive color work. SHORT 2.6mm is the favorite of artists specializing in finesse. Can I order a complete set of eccentrics? Yes, you can purchase all three eccentric variants (SHORT 2.6mm, STANDARD 3.7mm, and LONG 4.5mm) individually from tatuat.ro. Having the complete set gives you total versatility, allowing you to adapt the Dragonfly X2 machine to any tattoo style and any client requirement.
