Sven Gustaf Wingqvist |
Sven Gustaf Wingqvist (1876–1953) was a Swedish engineer, inventor
and industrialist, and one of the founders of Svenska Kullagerfabriken
(S.K.F.), one of the world's leading ball- and roller bearing makers.
Sven Wingqvist invented the multi-row self-aligning radial ball bearing
in 1907.
->1876: Born December 10 in Hallsberg outside Örebro, Sweden. Son of the railway station inspector at Hallsberg S. D. Wingqvist and Anna Lundberg.
->1894: Graduated from Rudbecksskolan in Örebro (Örebro Technical Elementary School).
->1899: Employed as operating engineer at Gamlestadens Textile Industry in Göteborg where he worked many years to find a solution to the problems with frequent break downs in the ball bearings for the main drive shafts. This was caused by the ground conditions with lots of clay that the factory was built on and the shaft bearing supports moved some fractions of millimeters from time to time, hardly measurable, inducing enormous extra forces in the "stiff" bearings that was available at that time.

Wingqvist spend more and more time on the development of bearings in
general, collecting all sorts of technical achievements and new ideas
that was presented continuously on the ball bearing concepts around
Europe. In particular he carefully studied the report presented in 1902
by professor Richard Stribeck working at the Institute of Technology in
Dresden, Germany, where he had compared ball bearings versus plain
bearings from a scientific point of view. Wingqvist soon realized that
the ball bearing techniques had a future and that there was room for
innovations. On his initiative a small workshop was set up within the
premises of Gamlestadens factory where they could carry out tests with
different designs and steel materials. In 1906 he was granted a patent
for a single-row self-aligning ball bearing (Swedish patent reg. No.
24160) but this type of bearing had the disadvantage that it could not
stand very much axial loads. His work continued in order to find the
solution for a self aligning bearing that also could carry some axial
loads.
->1907: On the initiative of Sven Wingqvist and the owners of Gamlestadens Textile Industry, SKF was founded February 16, at first as a subsidiary company to Gamlestadens Textile Industry. He was appointed the managing director as well as technical manager.
Axel Carlander, son of one of the owners of Gamlestadens Textile
Industry, was appointed CEO for SKF. (Axel Carlander held the position
as CEO for SKF until 1937). May 21: SKF sends in the patent application
to PRV for a multi-row self-aligning radial ball bearing. Patent is
granted June 6 with patent reg. No. 25406. Inventor: S.G. Wingqvist. In
the patent application a double-row as well as a triple-row ball bearing
is described. Within the same period of time, patent applications is
sent out by SKF to 10 different countries, among them France, Germany,
England and the USA and patent is granted in all countries within a
short time. The door was now open for the world wide expansion.
