Nils Arvid Palmgren (30 April 1890 – 14 November 1971) was a Swedish engineer and inventor, best known for creating the Spherical roller bearing[1]. His work at SKF and his contributions to bearing life theory remain fundamental in mechanical engineering and tribology.
Palmgren was born in Falun, Sweden. He completed secondary education in Stockholm in 1909 and passed his reserve officer's exam in 1911. In 1916 he graduated as a civil engineer in road and water construction from the KTH Royal Institute of Technology. He later received a Doctor of Technology degree from KTH in 1930.
Career
Palmgren began his career at the Swedish Road and Water Construction Authority in 1916. In 1917 he joined SKF as a research engineer. In 1919 he patented the self-aligning spherical roller bearing in 19 countries, with Swedish patent no. 53,856. This invention revolutionized mechanical design by allowing bearings to accommodate misalignment and heavy loads.
