Electron 2AC124 2-Groove V-Belt Sheave, 1-3/16" Bore

This is a cast V-groove sheave marked ELECTRON, with a cast part mark read as AC124 and a stamped 1-3/16 inch bore. The record carries it as model 2AC124. A sheave of this kind is keyed to a shaft and carries V-belts to transmit power between an electric motor and driven equipment.

In common industry sheave numbering, the leading digit is the number of grooves, the letters give the groove type and belt section, and the last digits give the nominal outside diameter; for example a 2AK124 is a two groove sheave of about 12-1/4 inch OD for A or 4L belts. The marks on this part have not been matched to a published catalog, so groove count, groove section and outside diameter should be measured before ordering belts or matching it to a drive.

Maintenance mechanics, HVAC and air handler service technicians, farm equipment repairers and machine builders use cast finished-bore sheaves of this size on blowers, fans, pumps, compressors and other belt driven equipment running on a 1-3/16 inch shaft.
