Flowserve SSA-5.5-2.6-1.87-TO-2.25-1.78 Shaft Sleeve Adapter is a 5.5-inch-long two-end coupling that transitions from a 2.6-inch outer diameter with a 1.87-inch bore (keyed) to a 2.25-inch outer diameter with a 1.78-inch bore. The 2.6" OD/1.87" ID end is keyed for secure torque transmission, while the opposite end provides a 2.25" OD and 1.78" ID bore to accept the matching sleeve. This Flowserve component is used in pump and mechanical assemblies where you need to connect shaft sleeves at these two size steps.
