Daikin-McQuay GC10116 Shaft

The Daikin-McQuay GC10116 Shaft is a critical industrial-grade drive component engineered for high-demand HVACR applications. This OEM replacement shaft features a 1.25" outer diameter (OD) and an extended length of 70.25", providing the necessary reach and structural integrity for large-scale commercial air handlers and blower assemblies. Built from high-tensile steel, the GC10116 is designed to handle high-torque loads while maintaining precise alignment to prevent premature bearing failure and vibration-related system fatigue.

For technicians performing HVAC blower shaft replacement, the GC10116 ensures a drop-in fit that adheres to original equipment manufacturer tolerances. Using a genuine McQuay drive shaft is essential for maintaining the rotational balance and operational efficiency of the motor-to-fan connection. Whether you are addressing a sheared shaft or performing preventative maintenance on a Daikin-McQuay air handling unit, this specialized component provides the durability required for continuous 24/7 industrial environments.

• Precision Dimensions: Exact 1.25" OD x 70.25" L specifications guarantee compatibility with specified Daikin and McQuay systems without needing field modifications.
• Industrial Build Quality: Constructed from robust materials to resist deflection and withstand the high mechanical stresses of commercial HVAC operations.
• System Longevity: Helps maintain peak equipment performance by ensuring smooth power transmission and reducing stress on connected mechanical components.
• OEM Reliability: As a Genuine Daikin-McQuay part, it meets the exact metallurgical and engineering standards of the original equipment.

• Is this shaft compatible with all 1.25" blower assemblies? No, while the OD is standard, the 70.25" length and specific machining are designed for specific Daikin-McQuay equipment models. Always verify your model and serial number.
• Does this include the keys or mounting hardware? This SKU generally includes the shaft itself; it is recommended to inspect existing keys and bearings for wear and replace them during the shaft installation.
• How do I prevent future shaft failure in my AHU? Ensure proper belt tension and sheave alignment during installation, as over-tensioning is a leading cause of shaft fatigue and bearing failure.
