Great deal great customer service

I used this to build a horizontal manual mill machine. They work very well and provide sturdy support for the spindle. Accurately machined with consistent sizes and spacing. Would recommend them, especially at the price point.

Decent quality bearing set. Needed to clean bearings well before use.

Got what I paid for and what I expected. They were not straight right out of the box, but loosening and then re-tightening the mounting bolts helped straighten them enough for my small hobby diy CNC.

Fast delivery and works well

Great product

I haven’t had the chance to use this yet but after inspecting it I find that it will work adequately

Highly recommend these. I'm using them on a sled in conjunction with a bandsaw. The supported rails are a must for my use - I tried the rails with brackets and they allow too much play. Very happy with this purchase.

I have studied, researched and looked far and wide at multiple options and then I discovered this system.On a line of one to ten, I rate this a full ten. It was the perfect choice for my application where I required precision movement for sake of accuracy for making large timber cuts with my electric chain saw. It solved my problem with the utmost satisfaction. As for load bearing capacity with four carriage blocks the weight distribution is excellent for guiding the chainsaw and bar for making plunge cuts. With a secondary horizontal linear rail system it guides the horizontal cut making for a superb cut. Highly recommend the quality that was put into this system. I purchased the metric bolts from ACE HARDWARE and was amazed at the ease and precision the bolts inserted so well. The quality of the carriage blocks are what you would expect. The stainless steel rails allow the carriage to glide with ease.Highly recommend. Hope this helps.

The rails were nice and straight, no bowing, and the SS tracks are well polished. The linear bearings need some adjustment to get them to run relatively smooth. Even after adjustment, the bearings seem rough until you put a load on them after which they run nice and smooth.These work well for my purpose (linear guide rails), but I would hesitate to use them for high precision or low load applications (CNC, printing) simply due to the way the bearings behave without a load.
