SUFFIXES

(Spherical Roller Bearings)

Radial Internal Clearance Suffixes appear after the basic Consolidated number on both our boxes and one face of our Spherical Roller Bearings. Torrington uses suffixes F1, F2, F3, F4 and F5 to define similar Radial Internal Clearances for their Spherical Roller Bearings. The use of this Table will enable you to interchange Torrington suffixes to Consolidated suffixes.
