Description is wrong.

Description says 1500mm length. Ordered on this basis. Its length is only 300 mm. The description is wrong but the details are correct. The problem needs to be fixed.

Cons
  • Obsolete model

High Quality

I bought these parts for the Z axis of my CNC router. The parts were well packed in sealed plastic bags and protected from damage in transit. All the details were there and the quality seems exceptional. The wiper seals on the carriages add some friction as the carriages move, but the ball drive and stepper motor easily overcome that force. I am very pleased with the fit and performance of these guides.

Pros
  • Industry & Science
Cons
  • Doubt

Carriages are high quality - strong, all deflections are within norm

Carriages are high quality - strong, all deflections are within norm. All the blocks I received were black and silver, not tri-color as you see in the listing. The seller assured me that they are identical in everything except for the color. The packaging comes in a cotton envelope from China with bearings installed on the guides and in plastic bags. There's a lot of grease on everything, so be prepared to wash things first. You should then use the bearing grease of your choice. Also included…
