Pollard Ball and Roller Bearing Company with its headquarters at Ferrybridge, West Yorkshire was a manufacturer of ball and roller bearings founded by John King. Formerly it had been known as Ferrybridge Industries and was originally a small family motor repair firm, Whitehouse Motor Industries, Ford dealers. [1] [2] [3] Ferrybridge owned Pollard Bearings Limited. [4]
Subsidiaries were established in France, Canada and USA. [5] In 1964, 30 percent of the trade was direct with the motor industry in Germany, Italy, France, Sweden, and the US.
In May 1969 government pressure exerted through the Industrial Reorganisation Corporation required the sale of all the capital of Pollard to Ransome & Marles. The grounds for the pressure were given to be as follows:
AB SKF is a Swedish bearing and seal manufacturing company founded in Gothenburg, Sweden, in 1907. The company manufactures and supplies bearings, seals, lubrication and lubrication systems, maintenance products, mechatronics products, power transmission products, condition monitoring systems and related services globally.
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.
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.
Hardy Spicer is a brand of automotive transmission or driveline equipment best known for its mechanical constant velocity universal joint originally manufactured in Britain by Hardy employing patents belonging to US-based Spicer Manufacturing. Hardy and Spicer soon became partners. Later Spicer became Dana Holding Corporation.
John Leonard King, Baron King of Wartnaby was a British businessman, who was noted for leading British Airways. He was also directly involved with the "dirty tricks" campaign waged by British Airways against Virgin Atlantic.
A linear-motion bearing or linear slide is a bearing designed to provide free motion in one direction. There are many different types of linear motion bearings.
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.
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.
Ransome & Marles Bearing Company Limited was a British company which made ball bearings and roller bearings. It was founded during the First World War to make bearings for aircraft and other engines. Before the war most bearings had been imported, chiefly from Germany.
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.
Hyatt Roller Bearing Company was a manufacturer of roller bearings from 1892 to 1916, when it was acquired by General Motors. It continued as a distinct division of GM for many years. The company struggled at first, then entered a phase of profitable growth under the leadership of Alfred P. Sloan. The innovative design of Hyatt's roller bearings made them more durable and efficient than others. They were widely used in early automobiles by various manufacturers, and in industrial vehicles and equipment.
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.
The Industrial Reorganisation Corporation was an entity established by the Government of the United Kingdom to reorganise British industry.
