L110B inserts are also commonly referred to as L110B spiders. Bronze jaw coupling inserts go between two L110 hubs, prevent a steel on steel contact, and allow for a slight misalignment between two shafts. When replacing a coupling assembly, it is essential to note that the oil impregnated L110B bronze inserts are ideal for high torque but low speed applications.
