Schaeffler Technologies AG & Co. KG, also known as the Schaeffler Group (Schaeffler-Gruppe in German), is a German manufacturer of rolling element bearings [2] for automotive, aerospace and industrial uses. [3] It was founded in 1946 by brothers Dr. Wilhelm and Dr.-Ing. E. h. Georg Schaeffler. [4]
Aerospace bearings are the bearings installed in aircraft and aerospace systems including commercial, private, military, or space applications. Materials include M50 tool steel (AMS6491), carbon chrome steel (AMS6444), the corrosion resistant AMS5930, 440C stainless steel, silicon nitride (ceramic) and titanium carbide-coated 440C.
In the 1930s, a research engineer named Edmund K. Brown invented a new kind of needle bearing, which eventually became the majority of the company's business. [3] After World War II, in which the US had a large need for needle bearings for military aircraft like B-29 bombers, the production of bearings became the company's central product line.
A US Army soldier wearing MOLLE gear Universal Camouflage Pattern. Modular Lightweight Load-Carrying Equipment, or MOLLE (pronounced / ˈ m ɒ l. l iː / MOL-lee), is the current generation of load-bearing equipment used by a number of NATO armed forces, especially the British Army and the United States Army since the late 1990s.
Flat thrust bearings, the most common spiral groove bearings, are so named because one consists of a flat surface that opposes the grooved surface. Variations in this type of bearing come from the nature of the spiral surface and the type of fluid flow. The following is a list of the different types of flat thrust bearings: With transverse flow
A ball bearing. 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.
The IDF load-bearing system or Ephod ("apron" or "avantail" in Hebrew) is the direct result of the long experience acquired over the years with the "commando web gear" originally worn by Israeli recon paratroopers during the War of Attrition, who made crude but comfortable Khaki or Olive Green waistcoats and assault vests incorporating many small canvas or Nylon pouches.
