Thomson 1"-ID LINEAR BEARING FLANGE UNITS THP SFB-16
The Super Ball Bushing® bearing has been the industry standard for self-aligning linear bearings for over twenty years. This bearing provides three times the load capacity or 27 times the travel life of conventional linear bearings. Besides the dramatic increase in load capacity, the Super Ball Bushing® bearing is self-aligning, lightweight and adjustable with a low coefficient of friction. It is a quick and easy replacement for high friction plain bearings. The wear-resistant, engineered-polymer retainers and outer sleeves reduce inertia and noise in critical, high speed applications.
