Linear Guide Rail,2 pcs SBR12 500mm Linear Rail+4 Pcs SBR12UU Blocks For CNC Machine

I took to ChatGPT to figure out a solution for a project screen above my bookcases. Something I could discreetly slide back out of sight and pull out when I wanted to use. Linear Guide rail was the solution....Upon receiving, well packaged and looked incredibly well made.The blocks slide effortlessly and you can increase the tension resistance.Because of how the blocks slide, they in theory can wiggle / lean slightly so you can either tighten the resistance or in my scenario, ensure the two linear rails are accurately positioned apart and attached to whatever you're connecting it with to ensure they stay in an upright position.They look incredibly strong and I'm only apply 10kgs to two blocks but no doubt they can handle so much more weight as per the spec (I had to use ChatGPT to convert the spec to actual weight per block just to validate as I'm a newb to these).Really pleased with the quality and they met my need perfectly. Would recommend and I'll consider for any future projects.

Rails work well no play in the bearings.
