Exactly what I expected. Ball bearings are low quality, but was to be expected.

Used smaller before. These are substancial.

I bought these rails to fabricate a custom TV mount for a VERY large flatscreen we bought. I wanted to be able to slide the tv to the side to be able to access a hidden area behind the tv where the receiver, etc would be stored. The tv weighs in at 97 lbs, and I am able to slide it back and forth on these with a light touch of only 1 finger. They seem to be well constructed and are well worth the price.

Lieferung Schnell und Problemlos. Es wurde zus?tzlich zu den Lagerb?cken ein Ersatzlager zum Austauschen Mitgeliefert. Top

Very well made!

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.

Perfect bearings slide smoothly, does as it should

These things are rock solid and extremely heavy duty. would definitely buy again, and in fact, I did.

I used this product for a slab flattening jig with my router. Even with a very dusty environment, the bearing slides easily, maybe even too easily as I went off the end of the rails once, but that is really my bad. I wish that there were female threads at the end of the rails inline with the rail axis to facilitate adding a stop to prevent going off the end. When it went off the end, a single ball bearing did dislodged and was lost, but that still didn't prevent it from moving smoothly on the rails even after that.
