Description
The York S1-001-07110-702 Steel 1/4″ Square x 4″ Long Key is a mechanical drive element used in rotating assemblies to lock hubs, pulleys, or blower components onto motor shafts. It is installed within fan and blower drive system where the torque transfer between the shaft and the mounted part must remain secure during operation in HVAC systems. It fits into matching keyways to prevent slippage and maintain precise alignment of rotating equipment. It operates as part of the mechanical transmission interface in machinery, supporting stable rotational motion, reduced mechanical consistent air flow-driven performance across heating and cooling equipment.
