York S1-028-15471-000 1" Shaft Rubber Isolator Bearing

The York S1-028-15471-000 Shaft Rubber Isolator Bearing is a vibration-damping part that is used in HVAC equipment to hold rotating shafts and reduce noise and damage. The elastomeric isolator has a 1" shaft interface that absorbs mechanical vibration between motors, fans or blower assemblies and their mounting structure. It is installed in air handlers, rooftop units, or packaged systems and maintains alignment and reduces bearing and housing stress. This bearing is used to reduce vibration and transmitted forces, leading to a smoother operation, moving parts, and a quieter performance of heating and cooling systems.
