Exactly as described

Replaced old bearings on 3D printer. The flange mounting holes lined up perfectly with my existing brackets.

Good quality but tight fit

Needed some break-in time on the shaft, but once loosened up, they move very smoothly. Good value.

Perfect for CNC Router

Smooth operation on my gantry system. The extra length provides much better stability than standard bearings.
