Genuine HRB
Checked the logo and packaging. Definitely authentic. Running quiet in my 3D printer upgrade.

Good value
Works well for low speed applications. Packaging could be better but the bearing is genuine and functions well.

Perfect fit for my motor
Ordered the 61805 ZZ for a spindle repair. Dimensions were spot on and spin smoothly. Genuine HRB quality.

Solid bearing
Using the 2RZ version for a dusty environment. Seals seem tight. Good quality steel for the price.
