Genuine Japan quality

I have used many bearings before, and these feel superior. High-speed performance is stable without overheating.

Perfect for my drone build

These bearings spin incredibly smoothly. I noticed less friction immediately after swapping out the old ones. Genuine Japan quality is evident.

Good value for the set

Quality is good and sizes are accurate. Packaging could be a bit more protective, but the bearings themselves arrived undamaged.

Solid bearings for hobby use

Work well in high-speed applications. I deducted one star only because I wish there were more of the 608Z size included.

5 FAQ

Q: What is the maximum RPM rating?

A: The max RPM varies by specific bearing size and load. Generally, these are rated for high-speed miniature applications.

Q: Are these bearings waterproof?

A: These feature metal shields (ZZ) which protect against dust and debris, but they are not fully waterproof seals. Avoid submersion.

Q: Is the pre-applied grease high temperature resistant?

A: The bearings come with standard high-speed grease suitable for normal operating temperatures. For extreme heat, additional lubrication may be needed.

Q: Can I use these for skateboard wheels?

A: Yes, provided the size matches your wheel hub. The 608Z size is commonly used for skateboards.

Q: Do you sell these in individual sizes?

A: This listing is for an assorted set. Please check our other listings for single-size packs if you need specific quantities.
