OrangeA Linear Rail SBR Linear Guideway Rail and 4X Square Type Carriage Bearing Blocks for Automated Machines and Equipments

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.

I wasn't expecting what I received. These rails are professional quality that can more than likely accommodate a ton of load, honestly, 2,000 pounds. I don't know for sure, but man, these babies are perfectly chromed and glide so smooth. I have a Snap-On 9 drawer from the 1950s loaded with 200 lbs or more weight, and the rails and slides let you move the chest with a single finger.

I would not use these on a CNC machine, but for making tight tolerance slides for other applications, they are just fine.The linear motion bearings can be a bit rough when they roll, catching at points and rolling fine at others, like the balls have flat spots, but can’t visually see anything wrong with them.

These linear rails came well packed and shipping was fast. They appear well made and heavy duty. These are the second set I have gotten and would buy them again. The surface hardening is really tough. If they must be cut forget the hacksaw they need to be cut with an abrasive wheel. A dremmel will do the job. It took 2 discs to get through it.

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.

Items were received, measured for length, one was cut down to the exact measurement of 2000 mm; installed the next day.One of the SBR16UU Bearing Blocks, failed the 5mm hole thread requirement. I am going to oversize the thread to a 6 mm with "Tap and Die" set later. I am keeping it for a spare asset.Another SBR16UU Bearing Block had "frozen" rolls bearings (balls); however, I planned ahead after reading previous reviews. I ordered and received four spare SBR16UU Bearing Blocks. Minor delay in getting it running but the previous reviews were very helpful.

Ordered these, to use as rails for a loft on a tiny house. They work great. They are solid and well built. Will use again.

Decent quality.I was looking for linear rails for a project that needed sub milometer resolution.Two of the bearing blocks were binding up. Customer service sent out new ones.
