McQuay Daikin 020648604 Bearing

The McQuay Daikin 020648604 Bearing is a precision-engineered 2 3/16 inch ball bearing designed specifically for heavy-duty HVAC and industrial applications. This deep-groove radial ball bearing features an integrated set screw locking mechanism, providing superior shaft retention and preventing inner ring slippage under high-torque conditions. As a direct OEM replacement bearing, it ensures proper fitment and mechanical alignment in large-scale air handling units and chiller systems where axial and radial loads are significant. The robust construction minimizes rotational friction, reducing heat buildup and extending the operational lifecycle of critical rotating assemblies. Contractors often utilize this Daikin 020648604 HVAC part in pillow block or flange housings (bore size 2.1875") to maintain system stability and efficiency. When replacing legacy McQuay components, using this exact ball bearing with set screw is essential to match the original equipment manufacturer’s tolerances and performance specifications.

• Precision Bore Alignment: Designed with a 2 3/16" bore to match standard industrial shafting exactly for reduced vibration.
• Secure Shaft Retention: High-grade set screws provide a positive lock, ensuring the bearing moves with the shaft without eccentric oscillation.
• Enhanced Load Capacity: Engineered to handle high radial loads common in commercial HVAC fan and blower applications.
• Reduced Friction Design: Precision-ground raceways ensure smooth operation, lowering energy consumption and noise levels.
• Direct OEM Compatibility: Eliminates the risks associated with generic aftermarket parts by adhering to Daikin-McQuay technical standards.

Is this a direct replacement for legacy McQuay part numbers?
Yes, the 020648604 is the current OEM replacement for existing McQuay and Daikin units requiring a 2 3/16 inch bore bearing with set screw retention.

Does this bearing include the housing or just the insert?
This specific part number refers to the bearing insert with set screws. If your application requires a complete pillow block or flange assembly, verify the housing condition separately.

What is the proper torque for the set screws?
Set screws should be tightened to manufacturer specifications to ensure firm contact without deforming the inner ring or damaging the shaft.
