### ⭐ 1.0 out of 5 stars







  
  
    High failure rate.
  

*by N***L on Reviewed in the United Kingdom on 6 December 2020*

I bought these for my 3d printer.  I've already had 1 fail after about 20hrs of printing.  The bearing has a lot of play in it and started squeaking.  I replaced the bearing but it now seems like one on another axis is also going the same way.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Unfortunately these didn't last very long for me.
  

*by C***N on Reviewed in the United Kingdom on 9 May 2020*

Sadly i cannot recommend these pulleys. I purchased them to use on the x-axis of my Anet A8 3D printer. Its been used a lot over the past few weeks and I've had four bearing failures. Each bearing has lasted about 25-30 hours of actual printing time. I have an adjustable tensioner on this axis and initially I thought I'd got the tension set too high, so i turned it down after the first failure but that didn't stop another three failing. I'm going to use the last one I have to repair the printer so I can make an idle pulley mount that can take more substantial bearings.

### ⭐ 1.0 out of 5 stars







  
  
    Failed within hours
  

*by W***L on Reviewed in the United Kingdom on 1 March 2021*

These are the second brand of these bought for a 3d printer, and again the bearings have all failed within a few hours of printing.  Avoid.
