    Can only be used with supplied bearings
  

*by D***S on Reviewed in the United Kingdom on 11 March 2019*

Unfortunately only the bearings that this comes with these rails fit. tried adding a second bearing to the rails and they are no good. However they are great rails and are silent running

### ⭐ 1.0 out of 5 stars







  
  
    very low quality
  

*by P***M on Reviewed in the United Kingdom on 14 March 2020*

Not a great product, the carriage has a lot of rotational movement which means it binds in use. I bought 2 for a 3d printer y axis and found the mounting holes are just under 4 mm which stops the bolts going through, so I had to grind then out to be able to mount the rails.They also don’t run very smooth on the track quite notch along the full length , not sure if this is the track or the carriage.
