High quality stainless steel

Using these for a small conveyor mechanism. They handle the load well and haven't shown signs of rust.

Solid basic bearings

Good for general miniature applications. Not industrial grade but perfect for hobbyist use and prototypes.

Smooth operation

Replaced the old bearings in my RC car motor. Much quieter and spins longer than the previous set.

Good value assortment

Great variety of sizes for the price. One size was slightly tighter than expected but loosened up after use.
