We've just had some steel shafts made up for a machine at work, they were supposed to be 50mm, a quick try of the 50mm bearing indicated something wasn't right.
Without digital verniers the manual type indicated something like 50.25mm (definitely not 2inch =50.8mm)
I tried some emery tape and made sure there weren't any burrs with a file.
Several questions. What is the accepted tolerance for bearing fitting ?
When you buy shaft, 50mm what do you get, 50 mm that a bearing should fit straight onto, or 50 mm that requires machining to a bearing tolerance ?
