Guide & full description
Complete guide: Inkmachines nr. 71-B - Alu bearing rod - 1pcs
The aluminum bearing rod no. 71-B is an original Ink Machines replacement part, part of the drive mechanism of the brand's rotary machines (also listed under parts for the Dragonfly and Stingray models). Its role is to guide the linear movement of the needle bar with minimal friction, thanks to the integrated bearing, and it replaces the old plastic rod. It is intended for artists who maintain their own Ink Machines machine and need to replace a worn component in the drive system. Sold individually (1 piece).
How to use
- First confirm that the issue is from the rod: with the machine off, manually move the needle bar and check if you feel lateral play in the bearing or points of resistance in the stroke.
- Turn off and completely disconnect the machine from the power source before any disassembly.
- Partially disassemble the drive mechanism with the appropriate size Allen/hex keys; if you encounter circlips, use dedicated pliers to remove them.
- Remove the old rod and clean the housing of debris and old oil.
- Lubricate the new rod with dedicated Ink Machines oil before assembly.
- Install the rod by sliding it into its housing, without forcing — the part should go in smoothly and aligned.
- Reassemble the mechanism in reverse order of disassembly and tighten without over-stressing the threads.
- Test: first manually move the needle bar (smooth movement, no play), then start the machine at low voltage and listen for noise and vibrations before using it for work.
Tips from us
- Periodically lubricate the bearing area with dedicated oil — dry friction is the main factor that shortens the part's lifespan.
- Never force the rod during assembly; resistance means misalignment or debris in the housing, not that the part is too tight.
- Keep the old part as a visual reference until you confirm the new one works correctly.
- Order the original part (no. 71-B) to be sure of the dimensional fit with your machine's mechanism.
- When you open the machine, have the other maintenance consumables (oil, possibly rod washer no. 71) handy so you don't have to disassemble it twice.
- After assembly, run the machine idle for a few seconds to distribute the oil before the first session.
Frequently asked questions
What exactly does this part do in the machine?▾
It is the aluminum rod with integrated bearing from the drive mechanism. It helps convert the rotary motion of the cam into the linear reciprocating motion of the needle bar, guiding it with minimal friction thanks to the bearing. The aircraft-grade aluminum keeps the component lightweight without sacrificing strength, which reduces motor strain.
Does it fit my machine?▾
The part is designed specifically for Ink Machines rotary machines and is listed under parts for the Dragonfly and Stingray models. It is not interchangeable with machines from other manufacturers. To be safe, check the part number (71-B) against your machine's mechanism before ordering — the original part guarantees exact dimensional fit.
How do I know it needs to be replaced?▾
Typical signs are: perceptible lateral play of the needle bar when moved manually, increased mechanical noise, inconsistent needle stroke without having changed the cam, visible grooves on the rod surface, or abnormal vibrations felt in the grip. Replacement is recommended at the first signs of bearing play or surface wear.
Why aluminum and not plastic or steel?▾
This version replaces the old plastic rod. Aluminum (here aircraft-grade alloy) is about three times lighter than steel, thus reducing the mass of moving components and motor strain, offers a good strength-to-weight ratio, and does not easily seize in contact with other metals. The integrated bearing eliminates sliding friction that would otherwise heat up and make the mechanism noisy.
How do I maintain it to make it last?▾
Regular lubrication with dedicated Ink Machines oil, cleaning debris from the bearing area, and avoiding operation at excessive voltage. In intensive professional use, such a part typically lasts around 1-3 years, depending on maintenance; lack of lubrication is what wears it out fastest.
What is the difference from rod washer no. 71?▾
They are different and complementary parts. The rod washer (no. 71) is a simple spacer washer that distributes axial forces, while the bearing rod (no. 71-B) is a complete component that ensures linear guidance with minimal friction. They are not interchangeable — check which part is worn before ordering.
