Bearings

Per http://www.shopsmith.net/forums/showthread.htm?t=3235&highlight=timken+bearings '''Note: Original equipment bearings from Shopsmith all have standard or normal radial clearance. Most power tool bearing specifications fall into the standard range. If a bearing part number does not identify a radial clearance number it is normally considered to be a standard clearance.'''
