Acroprint 150 Stamp Hammer Assembly – Replacement Part for Mechanical Punch Clocks
The Acroprint 150 stamp hammer assembly is a replacement component used in the popular Acroprint Model 150 mechanical punch clock. Although these clocks are no longer manufactured, thousands remain in service due to their durability and simple mechanical design. The stamp hammer is responsible for pressing the time and date imprint onto the time card, making it a critical wear component in older machines.
Over time, repeated stamping can cause wear to the hammer assembly or rubber platen, resulting in lighter or incomplete impressions. Replacing the stamp hammer restores proper printing pressure and improves readability of time card punches. This assembly is designed specifically for Acroprint 150 series mechanical clocks and does not fit Model 125 units.

Mechanical punch clocks rely on a series of motor-driven gears and stamping components that can be serviced individually rather than replacing the entire machine. Many businesses continue maintaining these clocks because replacement parts allow reliable operation for years beyond original production life.
