Overview
The Fafnir LSAO 2-15/16 is a heavy-duty pillow block mounted ball bearing unit designed for demanding industrial applications. This two-bolt base bearing features a solid cast iron housing and eccentric self-locking collar, pre-lubricated and ready for immediate installation. The LSAO 2-15/16 model excels in applications with heavy loads relative to shaft diameter or where considerable shock loads are present.
