pfrederi 18,714 #1 Posted May 28 (edited) Been renovating some old school cast iron spindle units. The upper bearing were in good shape but I was planning on replacing except all I could get new was made in China. (These are the older shafts and the bearings are odd 3/4" ID 40mm OD. Later WH units used more common 17mm ID 40mm OD) So I opened up the bearings and some other used ones I had accumulated and a new China bearing. Interesting differences From left to right Pacamor (Japan) steel ball carrier 9 balls General bearing company plastic carrier 8 balls (No origin marked) Nice (USA) plastic carrier 8 balls HBC (China) (New) steel carrier 8 balls So what bearings to use???? Since eh old spindles have grease fittings into the housing I guess i should leave off the inner cover?? Edited May 28 by pfrederi 2 Share this post Link to post Share on other sites
ri702bill 9,534 #2 Posted May 28 I believe the open sides face the center, the seals to the outsides. 1 Share this post Link to post Share on other sites

peter lena 9,309 #4 Posted May 29 @pfrederi see the OPPORTUNITY ? its not the bearing its the wrong / generic lubrication in them ! wide rubber side grease shields , is the saving grace ! every bearing failure I have had was ELIMINATED ,WITH A CLEAN OUT, AND LUCAS XTRA HD GREEN CHASSIS GREASE , WAL MART $ 8 , ALL MY MOWER DECKS , AND RELATED DRIVE POINTS , operate quietly , easily , no WHYINING , rate at 550 deg flash point , polyurea rated , personally buy bearings on one standard , wide rubber side shields . no noise or failures . staring right at you , pete 1 Share this post Link to post Share on other sites
oliver2-44 10,781 #5 Posted May 29 (edited) Back at work we had large hydraulic pumps. The electric motor shared a bearing with the hydraulic pump where they bolted together. The bearings had one more ball than a common bearing. This gave the bearing a higher load rating. Those bearings cost a lot more than the standard bearing.

pfrederi 18,714 #6 Posted May 29 Good Info Thank you I have two of the 9 ball Pacamor bearing so I will repack them and then I am wondering new Chinese or repack the Nice (USA) bearing for number 3???? 1 Share this post Link to post Share on other sites

Actually I was making fun of being 55 years old looking back at stupid stuff I've done... My grandpa's logic: the level of balls is in direct and oppositional correlation with the limit of brains.... 1 Share this post Link to post Share on other sites
