While tattoo machines generally provide you with very durable and reliable products in themselves their components are not always so durable, and because many of the components of a tattoo machine are incredibly small in size they can be easily lost or misplaced, which is most commonly the case with the cam and bearing. To ensure that you don’t suffer too greatly from this loss we offer a selection of replacements and spares, including this particular option of the 4.2 extra-long stroke cam and bearing replacement, which has been manufactured using the highest possible quality materials to ensure the continued durability and effectiveness of the product.
