10PCS Miniature Radial Ball Bearings | 8 mm Bore Diameter | 12 mm OD

great

These bearings were used to replace worn sleeve bearings for small lathe handwheel shafts. The small size outer race was appropriate for the minimal clearance available. The application is shaft stabilization in low speed application and for that purpose, these bearings are entirely satisfactory.

As described!

Bearing sizes were accurate. Smooth rolling action

nice bits

Well made, runs smooth, don't know the longevity yet.

Received a packet of 10 pcs. They all seem to work fine but have only used two in an application so far. No issues.

Measured with calipers, dimensions are all completely accurate which is great. 8 out of the 10 roll very smoothly and I will be using them. Of the other 2, one grinds a bit and locks up every rotation, the other spins freely but grinds very roughly. I need smoothness so I won't be using those 2.

Es sind halt Kugellager, die scheinen zu funktionieren. Ich hatte aber erhebliche Probleme damit, 2 mm Achsen (40 mm lang) einzuschieben. Hier gehts um Toleranzen im 100stel mm Bereich. Nachdem ich die Achsen nahe der Schnittstelle leicht angefeilt habe, ging es. Eine Kontaktaufnahme mit dem Hersteller "sourcing map" scheitert an deren unsäglichem Webinterface. Es ist mir mit mehreren Versuchen nicht gelungen, dem Ding begreiflich zu machen, dass ich kein Bot bin.

It came so fast ... good item.

Conforme à la description.

Piccoli ma pratici e funzionali, ottimi per cinematica.
