Reznor 112042 Coupling
The Reznor 112042 Flexible Coupling is a critical mechanical interface designed for 5/16" shafts, commonly utilized in direct-drive blower assemblies and motor-to-pump linkages across Reznor's unit heater lineup. This flexible coupling 5/16" is engineered to mitigate shaft misalignment, which reduces vibration and prevents premature bearing failure in high-torque HVACR applications. Built with a resilient center member and durable hubs, the 112042 Reznor coupling provides a reliable HVAC motor shaft connector solution that dampens torsional stress during start-up cycles. As a precision-fit Reznor replacement part, it ensures proper power transmission efficiency in specialized industrial heating equipment. When servicing commercial air handlers or gas-fired units, using this 5/16 inch blower coupling maintains factory-spec clearance and noise levels. Its robust construction resists the thermal expansion and contraction cycles typical of gas-fired furnace environments, making it a standard inventory item for technicians performing preventative maintenance on legacy and modern Reznor systems.
Key Benefits for Technicians- Precision 5/16" Bore: Ensures a tight, slip-free fit on standard Reznor motor and blower shafts.
- Vibration Dampening: Absorbs mechanical shocks and minor misalignments to extend the service life of motor bearings.
- Resilient Construction: Designed to withstand the high ambient temperatures found within unit heater cabinets.
- Direct OEM Replacement: Eliminates the guesswork associated with universal couplings, ensuring correct torque transfer and shaft spacing.
Will this coupling fit a 1/2" shaft? No, this is a dedicated 5/16 inch shaft coupling; verify your motor and blower shaft diameters before installation.
Does this coupling include set screws? Most 112042 assemblies come with the required hardware to secure the hubs to the shafts, though verifying the integrity of the existing shaft keyway is recommended.
Can this be used in high-static pressure applications? Yes, the Reznor 112042 is rated for the torque requirements of standard Reznor centrifugal and axial fan configurations.
