Good variety pack

Great selection of sizes. I wish there were more of the 3mm size included, but overall good value.

Silent and Fast

Noticed a significant reduction in motor whine after swapping these in. Highly recommend for FPV builds.

Solid performance

Using them in small fans and they work well. Durability seems good so far after a month of use.

5 FAQ

Q: What is the tolerance on the 5mm inner diameter?

A: Standard ABEC-5 tolerances apply, ensuring a precise fit for most motor shafts.

Q: Is the grease suitable for high temperatures?

A: The standard grease handles typical motor heat. For extreme heat, high-temp grease may be applied.

Q: Can I use these for skateboard wheels?

A: These are miniature bearings. Skateboards typically require 608 size bearings, which are larger.

Q: Do these come with spacers?

A: This kit includes bearings only. Spacers are sold separately in our hardware section.

Q: Are these bearings corrosion resistant?

A: They are made of Chrome Steel. For high moisture environments, we recommend stainless steel variants.
