Straightside presses derive their name from the vertical columns or uprights on either side of the machine. The columns together with the bed and crown form a strong housing for the crankshaft, slide and other mechanical components.

A major advantage of the straightside press compared to the gap-frame machine is freedom from angular misalignment under load. Maintaining true vertical motion throughout the press stroke is critical to minimize tool wear and obtain accurate part tolerances.

Many high-volume close-tolerance stampings are made in straightside presses. These include electrical connectors, snap-top beverage cans, spin-on oil filter cartridge bases and refrigeration compressor housings.

Many high-volume close-tolerance stampings are made in straightside presses. These include electrical connectors, snap-top beverage cans, spin-on oil filter cartridge bases and refrigeration compressor housings. Tiny computer connectors are stamped at press speeds up to 1,800 strokes per minute (SPM) or more. Often two to eight or more parts are completed per hit. Precision stampings are also produced at low speeds. For example, large refrigeration compressor housings may be stamped at press speeds of approximately 12 SPM. The housing consists of two mating halves, which must fit together precisely in order to properly align the internal parts.
