💡 What is a spherical plain bearing used for in linear slide units and shaft alignment? It provides a low-maintenance steel-on-steel pivot that tolerates angular misalignment and heavy radial loads, so it's handy in tough motion systems. Good overview: - Fits linear slide units, pivot joints, and shaft alignment tasks in industrial machines. - Preferred when heavy shock loads, misalignment, or contamination would reduce sealed ball bearing life. - Useful in agriculture, construction equipment, and heavy-duty automation needing rugged plain bearings.
