## Customer Reviews

### ⭐⭐⭐⭐⭐ Arrived today and working perfectly for our application. No issues at all!
*by W***A on September 19, 2024*

So, there are no adjustments on these bearings, but the actual fit straight out of the packing is certainly good enough for this particular application. I'm not sure I'd use these for an ultra high precision application due to the lack of adjustability but I can't honestly say anything negative about these, as the price was so low, I'm actually surprised they're of decent quality.The mounted up easily and the slide showed little resistance and to this, I'm really pleased.I would purchase these again for use in basic operations as I believe they'll last a long time and provide good service for the next few years. Perhaps drilling and tapping a zerk fitting would prove worthwhile.These are a good value and a worthwhile product to have in your shop.

### ⭐⭐⭐⭐⭐ Well made
