Jaw couplings fail because of the following factors - overload, normal wear, excessive misalignment, insufficient lubrication, vibration and harsh environmental conditions.
These hubs feature sintered iron / cast iron construction for ensuring high compression strength and porosity resistance.
Scan down the keyway or bore column to the 2-inch bore entry. Read across the L190 column for locating the brand's UPC number - 12303. This number is prefixed with the Lovejoy UPC number - 685144.
These couplings are used in pumps, compressors, gearboxes, mixers, blowers and conveyors.
