WARNING: The holes for the rail supports are drilled a few millimeters at random.

Bought this set a few months ago for a planned project. Evaluating the details tonight, the rails, bolts, bearings and connectors seem ok so far, but the rail supports are GARBAGE! the holes for attaching the base are arbitrarily offset a few millimeters along the X and Y axes and discarded. If the supplier fixes this issue and can send me the correct replacement parts, I will change this rating. Otherwise be warned, at least part of this kit is GARBAGE.

Pros
  • bearing bearing has a certain load capacity, can hold in the ordinary precision rack, strong adaptability.
Cons
  • Ugly packaging

Watch the Price - Linear Roller Bearing

While there are a few complaints, if you choose the right app, this is great value for money. This is a medium precision slide at best, in an application that only requires low precision it should be fine, in a high precision application you will be disappointed. The screw is multi-threaded and seems to have a 10mm pitch, good when you need speed but not so good for accuracy, the nut also has a lot of play but again a relatively cheap thing. The glide shoes are noisy and feel a little rough…

Pros
  • This kit includes an optical axis and lead screw, sleeve bearing, linear rail mount, CNC indexer clutch and ball bearing.
Cons
  • boring packaging

Don't repeat my mistake.

The first thing to do when making a purchase is to select all of the bolts and screws that come with the kit. They are complete rubbish; They took it off before I could tighten them. It was almost comical. I've just looked in the Guinness Book of World Records and unfortunately there isn't a category for "Smallest Linear Bearings That Can Be Physically Produced" but I'm sure if they did they would take first place. They're only a fraction of the size of a tiny ball of solder that you can brush…

Pros
  • The lead screw is widely used for machine tools such as 3D printing.
Cons
  • Something else
