350mm Linear Rail - Stainless Steel
We've bought dozens of different rails, and they are all totally hit or miss on quality. We have finally been able to find a good source for really nice hard chrome plated rail! This means they will not rust or corrode, look beautiful, and they run very smooth. If you don't want to take the gamble on AliExpress, this is for you!
Rails come with a nice thick oil on them. For complete silence we recommend lubricating with grease!
- PS hard chrome ≠ stainless steel, but "hard chrome" doesn't mean anything to a lot of people, so we call it stainless just for simplicity.
Not everyone coming here may be familiar with the projects so here's some useful links:
- Github where the project lives
- Discord where we discuss the project and many other wonderful things with wonderful people
