Description

Key Characteristics and Function

• Definition: A precision-turned rod that links the motor’s internal rotor to external air-moving components (such as HVAC fans or industrial blowers).
• Material (SS): Made from stainless steel grades like SS 304 (for general or food/chemical use) or SS 316 (for superior corrosion and seawater resistance).
• Corrosion Resistance: The chromium content in stainless steel forms a passive oxide layer that stops rust, making it ideal for humid, wet, or chemically aggressive environments.
• Common Sizes: Frequently comes in standard residential and commercial diameters like 1/2-inch or 5/8-inch, depending on the power and size of the unit.
• Primary Role: Rotates with the motor to spin the blower wheel, moving air through HVAC systems, air conditioners, refrigeration units, or industrial exhaust systems while resisting bending and shear loads.
