Timken TAN17 Bearing Locknut For 85 mm Shafts

The Timken TAN17 bearing locknut is a steel, standard TAN Series nut engineered to securely position bearings, adapter sleeves, and withdrawal sleeves on 85 mm shafts in industrial power transmission systems. Used across conveyors, gearboxes, mining equipment, paper mills, steel mills, and other heavy-duty machinery that utilize spherical roller bearings, it helps maintain accurate bearing retention and resists loosening under vibration and demanding operating conditions. Designed for use with compatible lock washers to provide positive mechanical locking, the TAN17 features right-hand threads (3.340-12 NS Class 3), an outside diameter of 4.411 in (112.04 mm), a face diameter of 4.031 in (102.39 mm), a width of 0.635 in (16.13 mm), and 12 threads per inch; locking type is standard (Not Self-Locking) and it uses lock washer TW117. Manufactured by Timken (MPN TAN17) as part of the TAN Series bearing locknut family, common replacements include TAN17-2 and equivalents SKF AN17 and NTN AN17.
