Igus inc. introduces igubal, the only all-thermoplastic line of rod ends, spherical and pillow block spherical bearings, as a lightweight alternative to metal. The igubal system of self-lubricating, engineered polymer, self-aligning bearing elements are molded in standard sizes for easy retrofitting. The self-alignment feature eliminates the need for absolutely precise placement of shafts and housings, saving time and aggravation during the installation process. All igubal parts are made from high-performance polymers, offering many benefits over traditional steel counterparts, including contaminant resistance, vibration dampening and an 80% decrease in weight.

The low-friction igubal race is insert-molded into the housing for a money-saving, two-piece structure, rather than the usual three-piece design. The housing is made of an impact-resistant, reinforced thermoplastic. The bearing is also made of a low-wear thermoplastic compound. The insert-molding process allows for very small clearances between the two parts, yet the spherical bearing has the necessary freedom of movement within the housing to compensate for any shaft misalignment.

Without the third element, the race between the housing and the bearing, the self-lubricated inner diameter of the igubal bearing takes the brunt of the wear caused by any shaft rotation. This means longer life and less part replacement. The thermoplastic nature of igubal provides a lightweight, maintenance-free, strong, shockload-resistant alternative to steel, with service temperature tolerances between -40„a F and 176„a F. In addition, igubal is highly resistant to corrosion, chemicals and contaminants, for the smoothest possible long-term performance. Applications include agricultural and construction equipment, as well as exercise, marine and packaging equipment, and any lift or variable alignment applications.
