💡 What is a spherical bushing used for in linear slide unit and pillow block shaft applications? A spherical bushing provides a low-friction pivot and self-aligning support for rotating shafts under load. - Ideal for pillow block bearings and linear slide unit guides that need alignment compensation and robust plain bearing support. - Chosen when sealed ball bearing or ceramic options aren’t required and steel-on-steel contact is acceptable for heavy loads. - Great for high-temperature or high-load spots where a simple, handy plain bearing outperforms more complex sealed units.
