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.
Q: Is the inner diameter exact?
A: Yes, they follow ISO standard dimensions for the 61800 series.
Q: Are these bearings pre-lubricated?
A: Yes, all units come with standard grease lubrication from the factory.
Q: What is the difference between ZZ and 2RZ?
A: ZZ has metal shields for low friction, 2RZ has rubber seals for better protection against dust.
Q: Do you ship internationally?
A: Yes, we ship globally via standard courier services.
Q: Can I use these for high speed applications?
A: They are suitable for moderate speeds. For very high RPM, consider ceramic hybrid options.
