I give this product five stars because it worked great. I have a Homelite Jacobsen 624 snow blower and this bearing is used inside the sprocket and pinion which rotate on a shaft. The original was incomplete and only part of the housing of the original bearings. Homelite or Jacobsen no longer sell this part and they don't provide specs for a person to find a replacement bearing. Well, thanks to my own research and measurements, THIS IS ONE! Anyone who owns snow blowers like mine should find this part here. The Homelite/Jacobsen part number is JA343470.
