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.

Fast shipping and great product
Exactly what I needed for my RC car motor. Installation was easy and the fitment was precise across all sizes in the pack.

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.
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.
