Review on 🖨️ ReliaBot Linear Carriage Printer Machine: Superior Printing Performance and Precision by Calvin Chavva

I purchased these in addition to the other two rails I have on the rails I previously purchased. They were of a different type, with a gray border. They come in a sealed tear resistant pouch with a liberal coating of light machine oil. Looks like a bag of ramen spice :D The bag is small enough to prevent the plastic strip securing the same size BB as the guide from slipping off and allowing the BB to escape. At first they were fine, although one had a little more resistance than the other. Towards the end of my installation, one of them started to noticeably drag, although I didn't see any dirt, debris, or any reason for it. The remaining bearing block was still acceptable. Upon closer inspection, it was found that the red plastic finish coat/paint on each block was able to push through the body of the blocks at the edge of the track. I don't know if that was the reason as bb looked perfect. However, I will go back and buy the appropriate type. They just look a little cheaper to make.
