The BARDEN Corporation, part of SCHAEFFLER Group, is a world leader in the design and manufacture of super precision ball bearings. 

The 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. 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 application.

BARDEN super precision bearings come in inch or metric dimensions with diameters ranging from 4mm (5/32") OD up to 300mm (11½") 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. 

The BARDEN deep groove ball bearings have full shoulders on both sides of the raceways of the inner and outer rings. They can accept radial loads, thrust loads in either direction, or a combination of loads. Available in many sizes,with a variety of cage types.

The BARDEN range of angular contact ball bearings are ideally suited for high speed applications where both axial and radial loads are to be supported, and system rigidity requires preloading. They have a nominal contact angle ranging from 10° to 25°and are available with machined phenolic cages and with separable (B type) or non-separable (H type) outer ring. The H type non-separable bearings (offered in 1900HC, 100HC, 200HC and 300H series)  use a larger complement of balls than is possible in the same size deep groove bearings resulting in a greater capacity and higher speeds because of the phenolic one-piece cage. The B type separable angular bearings utilize cages to retain the balls when the outer ring assembly (including cage and balls) is separated from the inner ring. This type of bearing has the same high speed capability as the H type bearing providing advantages for certain applications. Separable bearings simplify assembly of units where bearings are located in blind holes. The separable feature also permits dynamic balancing of a rotating component with inner rings mounted in place, apart from the outer ring and housing.

Metal cables are are stranded wires used in a wide variety of applications in aviation and many other industries. The term "wire rope" is also used when the cable diameter is larger than 3/8" (9.52 mm), with smaller gauges designated as cables or cords. They are specified in terms of their construction by the number of strands times the number of wires in each strand. For example, “7x19” means the cable with seven (7) strands, and 19 wires in each strand. 7x19 is the most flexible cable, approximately twice as flexible as its 7x7 counterpart.

Aircraft cables are encountered on or around the aircraft including flight control surfaces and tie-downs or other uses. In contrast to the commercial (industrial use) cables, aircraft  cables undergo extensive testing and are lubricated providing substantially better fatigue life. They conform to MIL-DTL-83420 specification. Sourced by leading manufacturers such as CONTINENTAL CABLE or CENTRAL WIRE Group of Companies (CWI) they are offered with or without coating (jacket) in different constructions, materials (such as galvanized carbon steel or stainless steel), diameters in inches and pre-cut or cut-to-order lengths in feet. Many of the offered aircraft cables are also included in U.S. DoD Qualified Products List (QPL) which relates to products, components, or materials, often used in aerospace or military applications, which have been examined, pre-tested & found to conform with all applicable standards or qualification requirements set by a certifying organization or government entity. 

Different flight control cables, general use cable, cable assemblies and related parts from various manufacturers (*) are also offered either as OEM or FAA-PMA approved parts including our own labelled (AVIATIONEU NEW ERA) product lines aircraft and industrial (general use) cables for applications when no compliance to MIL specifications is required. For additional information please consult the Product Description section and the supplied documentation.

(*) OEM aircraft cables & assemblies are offered from TEXTRON AVIATION and are intended for use on Cessna, Beechcraft and Hawker aircraft. FAA-PMA approved aircraft cables and parts are offered from McFARLANE® AVIATION and other manufacturers for use on different aircraft.
