Spherical Plain Bearing

AST Bearings’ website features a variety of white papers covering a range of spherical plain bearings, free of charge. These white papers include spherical plain bearings requiring lubrication (steel-on-steel) and maintenance-free spherical plain bearings, which are broken down into categories according to the sliding contact surfaces: steel-on-PTFE composite material, steel-on- PTFE fabric and steel-on-copper alloy. The white papers offer valuable and detailed information, such as design characteristics, materials, applications, temperatures and more for every product.

Lubricant Selection: What Every Design Engineer Needs to Know

Simply stated, lubrication refers to the age-old science of friction reduction. People have been using lubricants for thousands of years, experimenting with waxes and oils from vegetables, fish, and animals to move heavy materials with equipment designed to gain mechanical advantage. In more recent years, the discovery of petroleum oil in the 1800s ushered in a new era of lubrication developments as people learned how to refine this oil and use it for a variety of purposes. Machinery could now be developed to operate faster and under heavier loads by using lubricants to create a barrier that eliminates friction and metalon- metal contact.

The Ultimate Shaft-To-Hub Connection

Polygon Shapes - Multi-Faceted Problem Solvers Kinematically ground polygonal shapes have been used as drive connections for more than 45 years. What is now referred to as Polygon Systems was developed by Fortunawerke, Stuttgart, West Germany, who patented a grinding machine capable of producing matched polygonal shaft and bore diameters.
