September 1, 2020 is the 75th anniversary of Schaeffler Plain Bearings: Helmut Erges established "Mechanische Werkst?tten Helmut Elges GmbH" in Bielefeld on August 1, 1945. The company has been focusing on spherical plain bearings and sliding bearings very early, and is responsible for the development of many products currently available as standard configurations on the market, as well as some current effective sliding bearing standards. Since 1984, INA and FAG-independent companies operating on the market at the time-held equal shares in Helmut Elges GmbH until they were completely merged in 2002 Fowler Group. The ELGES product brand was retired in 2017. Since then, Schaeffler's sliding bearings have been listed under the INA brand.
"Sliding bearings are an indispensable part of our broad product portfolio. Without plain bearings, many applications would not be able to operate stably and reliably. Marcus Eisenhuth, CEO of Schaeffler Europe Industries ) Explained: "We have also worked closely with customers from the early stages of the design process to create added value for each bearing position.
Extensive and proven product portfolio—and all products from a single source
With its wide range of precision products, Schaeffler has been one of the technological leaders in the field of sliding bearings for many years: this series includes spherical sliding bearings with a bore diameter of 1500 mm, sliding bushes and rod ends with a bore diameter of 200 mm, And customer-specific solutions.

In the 1960s, Schaeffler successfully made two important developments: The first was the invention of the sealed spherical plain bearing design, which enabled the company to make breakthroughs in the construction machinery and commercial vehicle industries. The second is the development of ELGOGLIDE polytetrafluoroethylene fabric, which allows the manufacture of maintenance-free spherical plain bearings. At the same time, Algolide also provides special damping properties to enable it to withstand high static shock loads and alternating loads.
The continuous and in-depth development of Schaeffler sliding bearings has opened up new application areas one after another. The maintenance-free option allows users to create environmentally friendly designs and reduce construction and operating costs by minimizing size and eliminating maintenance costs.
Safety and stability: not limited to the construction industry
Used in hydraulic cylinders for mobile construction machinery, grinding rollers in cement mills, continuous casters in steel mills, rotor blade adjustment drives in wind turbines, road rollers, train doors and bogies, and escalators for optimal steering Capable pivot joints, airport baggage claim belts: all these applications require sliding bearings.
In construction projects, sliding bearings are installed on particularly sensitive interfaces, such as the glass roof of Berlin Central Station. This roof structure covers approximately 300 meters of railway platform and consists of a truss frame, which integrates numerous spherical plain bearings and bolt systems from Schaeffler. When external influences (especially wind) act on the steel structure, they provide the necessary length compensation.
On the other hand, at Wembley Stadium, the weight of the roof structure only relies on two bearings: each bearing supports 7,500 tons and has a design life of 100 years.
The Osman Gazi Bridge in Turkey was put into operation in 2016. Schaeffler provided 109 spherical plain bearings and 72 bushings for the connection points of various bridge sections and bridge cables and foundations. The area south of Istanbul is known for its special sensitivity to earthquakes. Therefore, the bridge is designed to continuously compensate for any vibrations, movements and loads that may occur.
The London Eye Ferris wheel is raised from the horizontal assembly position across the Thames to the vertical operation position. With Schaeffler's two large spherical sliding bearings, the contact pressure is as high as 450 N/m2. In operation, these bearings can compensate for the small movements caused by the wind. They have done this work for more than 20 years.
The spherical plain bearing manufactured by Schaeffler in 2019 has an outer diameter of 1900 mm and a weight of 4.7 tons. It is the largest spherical plain bearing in the company's history so far. It was installed on a cutter suction dredger-a work boat used to remove solid matter from the bottom of a body of water and transfer it to land. In response to this special requirement, a customized bearing was designed.
