The Volvo Group is a Swedish multinational manufacturing corporation headquartered in Gothenburg. While its core activity is the production, distribution and sale of trucks, buses and construction equipment, Volvo also supplies marine and industrial drive systems and financial services. In 2016, it was the world's second-largest manufacturer of heavy-duty trucks with its subsidiary Volvo Trucks.
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.
The Gothenburg School of Business, Economics and Law at the University of Gothenburg is one of Sweden's leading business schools, located in Gothenburg. It was founded in 1923 as an independent business college and is situated in the centre of the city. In 1961, it was integrated into the state-run university system, still as a separate college, but was then integrated into the University of Gothenburg in 1971.
A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or the directions of the loads (forces) applied to the parts.
In mechanical engineering, a rolling-element bearing, also known as a rolling bearing, is a bearing which carries a load by placing rolling elements between two concentric, grooved rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding.
A thrust bearing is a particular type of rotary bearing. Like other bearings they permanently rotate between parts, but they are designed to support a predominantly axial load.
The Wallenberg family is a prominent Swedish family renowned as bankers, industrialists, politicians, bureaucrats and diplomats, present in most large Swedish industrial groups, like EQT AB, Ericsson, Electrolux, ABB, SAS Group, SKF, Atlas Copco, Saab AB, and more. In the 1970s, the Wallenberg family businesses employed 40% of Sweden's industrial workforce and represented 40% of the total worth of the Stockholm stock market.
Leif Valdemar Johansson is a Swedish businessman. He was President and CEO of the Volvo Group from 1997 to 2011 and Chairman of Ericsson from 2011 until 2017 and is currently Chairman of AstraZeneca plc. In 2012, the Fokus Magazine ranked him as Sweden's 6th most powerful person.
Sven Gustaf Wingqvist was a Swedish engineer, inventor, and industrialist, and one of the founders of Svenska Kullagerfabriken (SKF), one of the world's leading ball bearing and roller bearing makers. Sven Wingqvist invented the multi-row self-aligning ball bearing in 1907.
Assar Thorvald Nathanael Gabrielsson was a Swedish industrialist and co-founder of Volvo.
Erik Gustaf Larson was a Swedish automotive engineer and the co-founder of Volvo. He held a Master of Science (M.Sc.) degree in mechanical engineering from the Royal Institute of Technology in Stockholm.
Björn Gustaf Prytz was a Swedish industrialist in the early 1900s and from 1938 to 1946 Minister Plenipotentiary in London for the Swedish government.
NTN Corporation is one of the most prominent manufacturers of bearings in Japan, second domestically only to NSK Ltd. The company is one of the largest exporters worldwide of friction-reducing products, such as constant-velocity joints.
Auburn Bearing & Manufacturing is a designer and manufacturer of ball and roller thrust bearings and custom machined components and is owned and operated in the small town of Macedon in Upstate New York. Founded in 1898, Auburn Bearing is one of the oldest continuously operating thrust ball bearing manufacturers in the United States. Auburn Bearing & Manufacturing is most known for its line of thrust bearings that incorporate a "V" groove raceway, historically known as the "Auburn Groove," which is specifically designed to reduce rolling friction by containing the ball bearings with four points of contact.
A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers. Despite what their name may imply, spherical roller bearings are not truly spherical in shape. The rolling elements of spherical roller bearings are mainly cylindrical in shape, but have a profile that makes them appear like cylinders that have been slightly over-inflated.
The automotive industry in Sweden is mainly associated with passenger car manufacturers Volvo Cars and Saab Automobile but Sweden is also home of two of the largest truck manufacturers in the world: AB Volvo and Scania AB. The automotive industry is heavily dependent on export as some 85 percent of the passenger cars and 95 percent of the heavy vehicles are sold outside of Sweden. The automotive industry and its sub-contractors is a major part of Swedish industry. In 2011 around 110,000 people were employed and the export income of 150 billion SEK accounted for 12 per cent of Sweden's export income. During 2009 128,738 passenger cars and 27,698 heavy vehicles were built in Sweden. Koenigsegg is also a famous Swedish company which makes some of the fastest cars in the world, but also some of the most expensive. They currently produce models such as the Jesko, Gemera, and CC850.
Ovako AB is a European manufacturer of engineering steel for customers e.g. in the bearing, transportation and manufacturing industries. Since 2018, Ovako has been owned by Nippon Steel Corporation.
A spherical roller thrust bearing is a rolling-element bearing of thrust type that permits rotation with low friction, and permits angular misalignment. The bearing is designed to take radial loads, and heavy axial loads in one direction. Typically these bearings support a rotating shaft in the bore of the shaft washer that may be misaligned in respect to the housing washer. The misalignment is possible due to the spherical internal shape of the house washer.
