Good Quality
Overall very satisfied. One bearing in the pack felt slightly stiffer than the others, but the rest were perfect for my robotics arm.

Highly Recommend
Great for miniature projects where space is tight. The stainless steel ensures they last longer than standard chrome steel options.

Perfect for RC
Used them in my RC car upgrade kit. The sizing was exact and they fit without any forcing. Great value for the price.

Smooth Operation
These bearings are incredibly smooth right out of the package. I used them for a custom drone build and the motor spin-up is noticeably quieter.
Q: What is the hardness rating of these bearings?
A: The stainless steel used typically has a hardness of HRC 58-60, ensuring durability and wear resistance.
Q: Is this suitable for high temperature environments?
A: The standard grease is rated up to 120°C. For higher temperatures, specialized lubrication may be required.
Q: Can I clean the pre-applied grease out?
A: Yes, you can clean them with solvent, but please note this may affect the warranty and requires re-lubrication.
Q: Are they shielded on both sides?
A: Yes, the ZZ designation indicates metal shields on both sides of the bearing to protect against debris.
Q: Do you stock non-standard sizes like 1.5mm bore?
A: We primarily stock standard integer sizes listed in the description. Please contact us for custom sourcing requests.
