Carrier KR11HY194 Pulley
The Carrier KR11HY194 motor pulley is a high-duty, cast iron sheave engineered for demanding HVAC power transmission. With a 6-inch outside diameter and a 1 1/8-inch bore, this fixed-pitch component provides the dimensional stability required for high-torque blower applications. Its heavy-duty cast construction ensures superior heat dissipation and wear resistance compared to standard stamped steel alternatives, maintaining precise belt alignment over extended run cycles.
Designed for 1-groove V-belt systems, the KR11HY194 is a critical replacement part for maintaining design CFM setpoints in commercial and residential air handlers. Proper installation on the 1.125" drive shaft is essential; technicians should verify the set screw is aligned with the shaft keyway to prevent rotational slippage and premature high-side bearing wear. This industrial HVAC pulley helps reduce vibration and noise, preserving the long-term integrity of the drive belt and blower assembly.
Key Benefits- Cast iron construction provides exceptional durability and handles thermal expansion better than lightweight pulleys.
- Precision-machined 1 1/8-inch bore ensures a secure, concentric fit on motor shafts, reducing harmonic vibration.
- The single groove design is optimized for standard V-belt profiles, ensuring maximum surface contact and torque transfer.
- Official Carrier OEM replacement part, guaranteeing exact fitment and performance in compatible rooftop units and air handlers.
Is this an adjustable sheave or a fixed-pitch pulley?
The KR11HY194 is a fixed-pitch cast iron sheave. It does not allow for RPM adjustments via pitch diameter changes; drive speed must be managed via the motor's VFD or by changing the pulley ratio.
How do I ensure this sheave doesn't seize on the shaft?
During maintenance or replacement, clean the motor shaft with an abrasive cloth and apply a light coat of lubricant. Transitioning to a new Carrier KR11HY194 ensures the bore surface is free of previous scoring or oxidation.
What happens if the belt is misaligned with this pulley?
Misalignment causes rapid belt fraying and increased lateral load on the motor bearings. Use a laser alignment tool or straight edge to confirm the 6" diameter sheave is perfectly coplanar with the driven pulley.
