  • I bought several of these to use for a garden novelty which consists of a auto engine metal radiator cooling fan which spins on a 3/8" metal rod. After trying various bearings which would last outdoors only a few months I tried these. These bearings (2/shaft) have been spinning 24/7 for at least 6 months now without the least sign of slowing down. This is outdoors through snow sleet and rain and here in the Midwest we have plenty of wind. Excellent product.
