Spot-on

everything i order from this company works well i have never received a inferior product from this brand and these Barings are great for so many 3d printing projects that require them.

Bought these to use on a hoist carrier, better quality than I thought they would have been from the previous reviews on here. These are an ABEC7 quality, which are not the highest but not the lowest either. All measurements are within tolerance and fitted well. They have a little bit of movement on the inner race but for what I need them for is OK. I needed a bearing for my CNC as well so used one of these and it’s all working well with no backlash, so would deffo buy again.

Free running bearings and look solid.

I can't give ia even one star - product is bad quality, outer ring is loose against inner ring and wobble against each other, also inner ring slightly bigger diameter - so when but on the rod it also loose and wobbles - - as to compare with my old bearing which do not wobble and fit perfectly on the inner rod - can't use it as when combined two bearings on the rod - it creates the blockage as they are loose. I wish I can return - but already damaged them installing them in the knuckle and trying to take them out, and remaining pairs are same bad

Giving it 3 stars as the photo shows not all bearings the same size. 29 at 4x12x4. And what appears to be one 4x13x5. Chinese packing gone astray. Fortunately I did not need all 30 for my project

The ID is meant to be 6mm but is about 6.1mm. Useless.
