ABSTRACT:
An improved load cell block (40) having a pair of slots (56) extending inwardly from first and second ends (46 and 48) to form an upper pair of beams (58), a lower pair of beams (60) and a central portion (62). The lower wall (66) of the slots (56) have a groove (72) formed therein for concentrating bending forces in the lower beams (60). The slots (56) terminate at an end wall (68) that is comprised of a bore (52) formed by drilling to have machining marks that are lateral to the longitudinal axis of the block to reduce the formation of stress cracks.
