INA-Werk

INA-Werk was a camera maker in Germany shortly after the Second World War. The firm was founded by Wilhelm and Georg Schaeffler, and began by making wooden hand-carts.[1] In 1954, the brothers patented a mechanical device for displaying rugs or similar items in sequence in a shop window.[2] Georg Schaeffler designed needle roller bearings which became the company's main product and the companies of the Schaeffler Group, including INA, still make bearings for many applications.[3]
INA is known for only one camera, the Navax 35 mm camera made in 1956. The camera has a metal focal-plane shutter, which perhaps employs INA's expertise in linear bearings.
