TOL has various meanings in the Architectural category. Discover the full forms, definitions, and usage contexts of TOL in Architectural.
Term describing deviation from the prescribed dimensional specifications for bore, OD and ring widths of standard bearings; the slighter the deviation, the smaller the tolerance and the closer the bearing comes to precision. The Annular Bearing Engineering Committee has standardized the tolerances for ball bearings, and the Roller Bearing Engineering Committee has developed similar tolerances for roller bearings; higher numbers mean greater precision.
