High quality miniature bearings

I use these for precision robotics projects. The dimensions are accurate and the metal shields keep dust out effectively.

Exactly as described

Ordered the 6902 ZZ size. They arrived quickly and matched the specifications listed. Will buy again.

Perfect for my drone build

These bearings fit perfectly into my motor housings. Smooth rotation and no noticeable play. Great value for the price.

Reliable for small motors

Using these in several 3D printer extruder upgrades. They run quietly and seem very durable so far.

Good but grease is thick

The bearings are well made, but the factory grease is a bit thick for high RPM applications. I cleaned and re-lubed them.

5 FAQ

Q: Are these bearings made of stainless steel?

A: No, these are made of Chrome Steel GCr15 for durability and load capacity. They are not corrosion-resistant stainless steel.

Q: Can I remove the shields to clean the bearings?

A: The ZZ metal shields are non-removable without damaging the bearing. We recommend purchasing open bearings if cleaning is required.

Q: Is the grease suitable for high temperature environments?

A: The standard grease is rated for typical operating temperatures. For extreme heat, high-temperature lubrication may be necessary.

Q: Do these come with rubber seals instead of metal shields?

A: This specific listing is for the ZZ variant, which features metal shields. Rubber sealed versions are available in a different listing.

Q: What is the maximum RPM for the 6903 size?

A: Maximum RPM varies based on load and lubrication. For light loads, the 6903 can typically handle up to 30,000 RPM.
