The balls are made with high-quality materials and have a smooth surface finish that reduces friction .They come in a convenient quantity and are compatible with different types of bearings. The only downside is that they may not fit all types of equipment, so it's important to double-check the specifications before purchasing. Overall, I would recommend these bearing balls for anyone looking for a reliable power transmission product..
