Perfect for my drone build
These bearings are incredibly smooth. I used the 3mm and 5mm sizes for my FPV drone motors and the RPM increase was noticeable. Great value for the assortment.

Solid choice for hobbies
Good variety of sizes. I wish there were more of the 2mm size included as I use those most often, but overall a great kit for the price.

Smooth operation
Used these for a small conveyor belt project. The 8mm and 10mm sizes fit perfectly. Very quiet operation compared to my previous supplier.

Excellent for RC cars
Replaced all the bearings in my 1/10 scale RC car. The ABEC-7 rating is legit, they handle high speeds without overheating. Highly recommend.

Good quality, packaging could be better
The bearings themselves are high quality and spin freely without grit. However, the small sizes were all mixed in one bag. I had to sort them myself.
Q: Do they come pre-lubricated?
A: Yes, all bearings come pre-lubricated with high-quality grease suitable for general purpose use.
Q: Are these bearings shielded on both sides?
A: Yes, the ZZ designation means metal shields on both sides, while 2RS indicates rubber seals on both sides. Please select your preference at checkout.
Q: What is the actual ABEC rating?
A: These bearings are manufactured to ABEC-7 tolerance standards, suitable for high-speed applications.
Q: Is there a warranty if a size is missing?
A: Yes, we offer a 30-day return policy. If any sizes are missing from the catalog kit, please contact us for a replacement or refund.
Q: Can these handle 20,000 RPM?
A: Yes, the ABEC-7 precision and chrome steel material are designed to handle high-speed rotations up to and exceeding 20,000 RPM depending on load.
