💡 What is a spherical plain bearing used for in shaft alignment and linear slide unit applications? It’s a handy choice when you need pivoting support and misalignment tolerance. - Provides pivoting support for rotating shafts and linkages in conveyors, presses, and hydraulic systems. - Handles heavy radial and shock loads; often chosen over sealed ball bearing when alignment varies. - Useful in linear slide unit assemblies and machines that need steel-on-steel contact; can be preferred to ceramic options in high-load, high-temp settings.
