L090B Insert | L090B Coupling Insert - L090B Spider (Bronze) filter_D40B48H Dimension (a): 1-7/8"L090B insert is a precision coupling insert precision machined from high quality bronze. L090B inserts are also commonly referred to as L090B spiders. Bronze jaw coupling inserts go between two L090 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 L090B bronze inserts are ideal for high torque but low speed applications.
