💡 What is a spherical plain bearing used for in linear slide units and pillow blocks? Spherical plain bearings let shaft assemblies handle angular misalignment and carry both radial and axial loads, so they're handy in machines that move, pivot, or wiggle under load. Quick take: - Fits applications where sealed ball bearing or ceramic options may not be needed - Used in linear slide unit guidance, pillow block bearing mounts, conveyors - Common in automation, gear linkages, and pivoting suspension joints
