💡 What is a piloted flange bearing used for in heavy-duty machinery? A piloted flange bearing supports and locates a shaft while simplifying mounting and alignment in tight-space flange applications. Quick overview: - Handy for conveyors, mixers, gearboxes and drive systems needing sealed ball bearing performance - Keeps shaft alignment in piloted 4-bolt flanges and works well with linear slide unit arrangements - Ideal when you want a relubricatable, sealed bearing that handles radial and light axial loads
