This is an original Ink Machines spare part: the spring lid along with its fixing screw. The role of the assembly is to cover the return spring chamber and keep it in proper compression, so that the needle bar returns consistently to the retracted position after each cycle. It is useful for artists who service their own rotary machine — when replacing the spring, during internal cleaning, or when the original part is worn or lost. It is delivered as a complete assembly (lid + screw).
What does the product include?▾
The complete assembly: the spring lid and the fixing screw, delivered together. The actual return spring is not included and must be ordered separately if needed.
Which machines is it compatible with?▾
This is an original Ink Machines part for machines that use the lid + screw system for the return spring. The description indicates compatibility with the X2 models, and the category also lists Dragonfly variants. Check your exact model before ordering, as some generations may have a different spring retention system.
Can I buy just the screw separately?▾
No. The lid and screw are sold exclusively as a set. The size, thread, and length are calibrated to work together; a generic screw, even with similar dimensions, may tighten improperly or damage the thread.
What happens if I work without a spring lid or with a worn one?▾
The return spring is no longer held in the correct compression. Incomplete needle retraction, vibrations, increased noise, and the spring may come out of its chamber. In practice, the machine becomes unsafe for precision work.
How do I maintain and sanitize it?▾
Being a metal part (lid with corrosion-resistant finish, stainless steel screw), it withstands disinfection with isopropyl alcohol and medical-grade solutions. Clean it after each session to prevent ink residue buildup and check its condition during every major machine service.
Can I adjust the spring tension using the lid?▾
No. The lid only keeps the spring in constant compression; it does not adjust tension. Return tension depends on the spring's characteristics. If you want a different return behavior, change the spring, not the lid.
