York S1-028-12012-700 Sheave
The York S1-028-12012-700 Sheave is a precision-engineered OEM replacement pulley designed for high-demand HVACR mechanical drive systems. Featuring a specific 1.1875" bore (1-3/16 inch), this fixed pitch sheave is critical for maintaining the correct blower RPM and ensuring optimal static pressure within your air handler or rooftop unit. This single groove sheave (BK110 series) typically accommodates 4L, A, 5L, or B section V-belts, providing the durable power transmission required for industrial applications. As a veteran technician knows, using a standard aftermarket pulley can lead to shaft slippage or vibration; this genuine York blower pulley ensures exact alignment and consistent airflow. Built to withstand the torque requirements of commercial blowers, the S1-028-12012-700 eliminates common drive-train noise and reduces premature bearing wear by maintaining a balanced rotational mass. When replacing this component, verify your shaft diameter to ensure the 1.1875 inch bore provides a true interference-free fit.
Key Benefits- Precision Bore Sizing: The 1.1875" bore ensures a secure fit on standard motor and blower shafts, preventing parasitic vibration and keyway damage.
- Optimized Power Transfer: Designed as a single groove fixed sheave, it maintains a constant drive ratio for stable air volume delivery.
- Heavy-Duty Construction: Engineered to original York technical specifications for resistance to groove wear and thermal expansion in high-cycle environments.
- System Compatibility: Direct OEM replacement for various York, Luxaire, and Coleman equipment, ensuring the drive package operates within motor amperage limits.
What belt profile is compatible with this sheave?
The S1-028-12012-700 is typically configured for B-section V-belts but can also accommodate A-section belts depending on the required pitch diameter and tensioner adjustment.
How do I prevent the set screw from backing out?
Always ensure the set screw is tightened directly onto the shaft key or flat spot. Technicians often use a high-temp thread locker for high-vibration air handling applications.
Can I use this for a variable speed application?
No, this is a fixed pitch sheave. For adjustable airflow requirements, you should utilize a variable pitch driver sheave on the motor side while maintaining this fixed pulley on the driven shaft.
