6 For more than six decades the Barden name has been synonymous with Bearings of exceptional quality and Precision and Barden Bearings are renowned worldwide for their high reliability and long operating life in challenging applications. Barden offers thousands of bearing variations which are used in virtually every sector of industry where there is the need to meet critical tolerances, high speeds and performance under demanding operating conditions. These include key components for the aerospace and defense sectors, vacuum pumps, food processing, robotics and medical equipment, including x-ray and CAT scanners and high speed dental handpiece s success has been built on a solid foundation of manufacturing and engineering design expertise, a highly skilled workforce and the ability to design bespoke engineered solutions for its ReachOriginally founded in 1942 by Theodore Barth and Carl Norden in the United States.

7 The Barden Corporation has built an enviable reputation for producing some of the world s most precise Bearings and is now a key strategic member of the multinational Schaeffler Group. The Group specializes in bearing technologies and Precision Products for aerospace, industrial plant and automotive industries and has over 74,000 employees at more than 180 locations worldwide. The Barden Corporation boasts state-of-the-art facilities at its manufacturing plants in Danbury, USA and Plymouth, UK, both of which have some of the world s most sophisticated machine tools, production equipment and inspection systems installed.

8 As a supplier to some of the most prolific blue chip companies across the globe, quality is of the utmost importance throughout the organization. stringent standards are applied to every element of the business, from the customer interface and design, through to production, packaging and s ProductsThe Barden product line is comprised largely of radial, single and double row, angular contact (separable and non-separable) and deep groove, Super Precision ball Bearings . All Products in the range can meet and will usually exceed ABEC 9 (ISO P2) standards , while full traceability back to raw materials can also be provided.

9 Barden s product offering also includes large and small diameter thin section ball Bearings . Produced in standard cross sections and configurations, these Bearings can be customised to meet the unique needs of each Super Precision Bearings come in inch or metric dimensions with diameters ranging from 4mm (5/32") OD up to 300mm (11 ") OD. A variety of seals, shields and metallic/non-metallic cage designs are available to meet most requirements. Many Barden Bearings operate comfortably at speeds reaching 2 million dN (bore in mm x RPM), or above.

10 Precision StandardsPrecision ball Bearings are manufactured to tolerance standards defined by the Annular Bearing Engineering Committee (ABEC) of the American Bearing Manufacturers Association (ABMA). These standards are accepted by the American National standards Institute (ANSI) and can be seen as broadly equivalent standards for the International Organization for Standardization (ISO).ABEC standards define tolerances for several major bearing dimensions and characteristics, which are divided into envelope dimensions (bore, OD and width) and bearing geometry.
