The double-joint Igubal bearings from Igus can be used in convertible roofs on cars, motorcycle trailers, food processing and packaging equipment, ventilator systems in trains and church organs.
The self-aligning bearings come in spherical ball as well as ball-and-socket varieties, both still retaining the same characteristics as the standard single-ended version. Ball-and-socket joints are simple links for moving applications and can also simplify the design and improve the technical merits of an application, according to the company. The three-part system has a wear-resistant Iglidur polymer liner, which guarantees an excellent service life. It also absorbs micro-vibrations, minimises noise and can be installed rapidly by hand. The retention force is much higher than the assembly force and thus ensures system stability even in extreme applications. The spherical bearing similarly absorbs vibrations, minimises noise and has an excellent service life. These characteristics are created by the Iglidur spherical bearing, which also creates the self-aligning effect.
The new double-joint bearings have already been integrated into a variety of applications, such as in a convertible roof on a car; smooth and quiet operation is an essential requirement of the drive mechanism, without the need for maintenance and additional misalignment compensation. The bearings have also been used in motorcycle trailers; high corrosion resistance and low weight are said to be important attributes for this application. For food processing and packaging applications, zero lubrication and resistance to chemicals are essential requirements for meeting hygiene regulations. The bearings have even been integrated in ventilator systems in railway carriages where cost, weight reduction and corrosion resistance are major concerns. Finally, they have been used in a church organ; a low weight and vibration damping are said to be the main advantages.
