Great bearings, too good for my use? Designed for use in wheelbarrow wheels that we use on boat carts. The original bearings are terrible - they last about 1 year before falling apart. They are way better and cheaper! However, the bushings they are pressed into are not machined with high precision. Some bushings simply fail, others cannot be pressed in. About 1 in 10 cases fits well. Where they fit, they're smooth and durable; Great! Otherwise they are useless.
