Cam Kit-ul nr. 85 from Ink Machines is a set of four replacement cams for the Stingray and Stingray X2 rotary machines. The cam is the part that converts the motor's rotation into the linear, up-and-down movement of the needle, and its geometry (eccentricity) determines the stroke length — that is, how the machine works and the type of work it is suited for. With four cams at hand, you can reconfigure the same machine for lining, shading, or packing without buying multiple machines. The set is aimed at tattoo artists who work on a Stingray machine and want flexibility in choosing the stroke.
What does the Cam Kit nr. 85 set contain?▾
The set includes 4 original Ink Machines cams: No. 80 (black, 3,5 mm stroke standard), No. 81 (blue, 3,5 mm stroke smooth), No. 82 (green, 3 mm stroke medium), and No. 83 (red, 2,6 mm stroke short smooth).
Which machines is the set compatible with?▾
According to the manufacturer, the nr. 85 set is intended for Stingray and Stingray X2 machines. Check your model before ordering to ensure compatibility.
What stroke should I choose for lines versus shading?▾
As a general rule: a shorter stroke — No. 83 (2,6 mm) or No. 82 (3 mm) — offers more control for linework and details, while a longer stroke of 3,5 mm (No. 80 or No. 81) is more suitable for shading and packing. Best is to test both variants on practice skin.
What is the difference between No. 80 and No. 81, if both are 3,5 mm?▾
Both have the same 3,5 mm stroke, but differ in the character of the movement: No. 80 is "standard", and No. 81 is "smooth". The difference is felt in the machine's feel, so the choice depends on your working preference.
Do I need tools to change the cam?▾
The manufacturer strongly recommends the Precision Ink Machines tool set for changing the cam and also provides an instructional video. Using the right tools reduces the risk of damaging the parts.
How do I maintain the cams and how long do they last?▾
The cam is an internal mechanical part, so it does not wear out like needles. Keep it clean and dry and check it periodically for signs of wear — increased noise, unusual vibrations, or abnormal play — and replace it when performance drops. During sessions, always protect the machine with barrier film.
