Description
The York 026-41939-005 Hub Square is a mechanical coupling between motor shafts and driven components in HVAC systems requiring secure rotational power transmission. This features a square bore configuration that prevents slippage under operational torque loads common in blower assemblies, fan wheels, and compressor drives. This structure handles continuous rotation, vibration, thermal expansion, and mechanical load. Factory-specified dimensions ensure exact fitment to designated models, maintaining proper shaft depth and alignment vital for balanced operation. Set screws or keyway provisions lock the hub firmly onto drive shafts bearing damage and component.
