Must be treated with extreme care. July 11, 2011
Reviewer: F500 from Sydney, Australia  
This bearing was as brittle as chalk and did not even survive the mounting process which consisted of being placed by hand into a split housing, the cap placed by hand over the bearing and the cap bolts tightened (much like the cap on a engine connecting rod).   I can't see how these bearings can be used as replacements for steel ball bearings in any application as most bearings are press fitted to some degree and if they can't survive fitting by hand then they certainly won't survive a press fit.   Purchasers should be aware of the brittle nature of these bearings and that they can not survive anything more than a clearance fit by hand and held in place by Loctite.
