Great for RC Cars

Used the 688ZZ bearings for my drone motors. They spin very smoothly and handle high RPMs without heating up.

Perfect Fit

Used the 684 deep groove bearings for my 3D printer upgrade. Exact dimensions and very quiet operation.

Good Assortment

The kit has a good variety of sizes. I wish there were a few more 685 sizes included, but overall satisfied.
