Customer Reviews for VEVOR Linear Guide Rail Set, SBR20 2200mm, 2 PCS 86.6 in/2200 mm SBR20 Guide Rails and 4 PCS SBR20UU Slide Blocks, Linear Rails and Bearings Kit for Automated Machines DIY Project CNC Router Machines

This was a reorder of an earlier purchase of linear rails and bearing blocks. The first set of rails/blocks were used for making a router sled. This set of rails/blocks were also well made. The only difference was this set of bearing blocks were threaded for M-5 bolts, about 12 mm deep. The first set of bearing blocks were sized for M-6 bolts (assuming same depth).There is no problem with that, just be aware there may be a difference. All the bearing blocks use an Allen wrench bolt for locking the blocks to the rail.

Nervig war die sehr lange Lieferzeit. Die F_rungen war sehr gut verpackt und erf_len ihren Zweck.

very strong two piece linear rail tracks just waiting for other parts to arrive to finish projects

Quality! making linear motion for printing press rollers. Working very well.

Bought these to upgrade an ancient cable drive ShopBot for my guitar-making hobby. For this application they look like they will work great, far better than the screen door rollers and unistrut used on the bot originally, and better than my previous upgrade to v-groove bearings and steel angles. For sure good enough for my occasional woodworking needs. Like a previous reviewer, I received four bearings not listed in the description, so now I have spares! I don_ think I_ put these rails on something that I rely on for a living unless I bought spares, and they seem a little noisy but hey, when the router is running I won_ hear it anyway.

I got these to mount a router for slab milling. There is no play in the bearings, and they are very sturdy. lightening fast shipping.

Gute Qualit?t und f_ meinen Zweck einwandfrei!

Barras de gran calidad y los patines no tienen holguras, son muy muy robustas, las barras redondas son de acero 20mm de di_etro y van montadas sobre unas bases de aluminio tambi_ muy robustasyo personalmente os las recomiendo. y llegaron puntualmente

Very heavy duty, will work perfectly for router copier that I_ making.It would be nice if they had mounting holes drilled in the base, but not a show stopper for me. I can drill my own mounting holes.

Il prodotto risponde alle mie esigenze, lo consiglio vivamente.Ho trovato anche un cuscinetto di riserva.Grazie
