-  * On Torrington inner cam bearings (from XLF member, Vanmor on Oct 8,2013 ((http://xlforum.net/forums/showthread.php?t=1688503)) ) \\ Got a box in today. There were eight BH-117 bearings in individual boxes. \\ However, these said KOYO on them and the bearings say BH-117 but are stamped TORR, not TORRINGTON.  \\ I found out that Timken, who was the former owner of Torrington needle bearings, sold the company to KOYO Seiko of Japan several years ago. \\ At the time of the acquisition, the plants in the USA were just renamed KOYO and still produced the same bearings as always. \\ My only worry is, did these come from China? \\ A lot of Japanese companies have followed the lead of other companies in other countries to make stuff in China and box it as made in Japan. \\ My KOYO bearings say made in USA. So be aware, your next cam bearings may say KOYO on them.+  * On Torrington inner cam bearings (from XLF member, Vanmor on Oct 8,2013 ((https://www.xlforum.net/forum/sportster-motorcycle-forum/sportster-motorcycle-era-specific-and-model-specific/frame-mount-evo-sportster-talk-1986-2003-models/157766-torrington-bearings-stamped-torr?t=1688503)) ) \\ Got a box in today.

   * Seals retain grease & exclude contaminants. Shields do not – they need an auxiliary seal to do that.   * Seals retain grease & exclude contaminants. Shields do not – they need an auxiliary seal to do that.
   * Often ball bearings that are sealed or shielded on both sides are cheaper (because they are more common).   * Often ball bearings that are sealed or shielded on both sides are cheaper (because they are more common).
