York S1-026-12850-000 Ball Bearing

The York S1-026-12850-000 Ball Bearing is a precision-engineered OEM replacement part designed specifically for heavy-duty rotation in blower motors, fan assemblies, and inducer systems. This 3/4" ball bearing is the gold standard for restoring mechanical efficiency in York and Johnson Controls residential and commercial units. In the field, we see these bearings most often used to mitigate shaft runout and reduce the harmonic vibration that leads to premature motor winding failure. By ensuring a low-friction interface, this HVAC ball bearing allows for consistent RPMs and optimized airflow, essential for maintaining the static pressure requirements of high-efficiency systems.

When you are dealing with a noisy fan or a seized inducer, utilizing a direct OEM HVAC part like the S1-026-12850-000 ensures the 3/4-inch bore and outer diameter tolerances match the original housing perfectly. This eliminate the need for shimming or field modifications often required with generic alternatives. This component is built to withstand the thermal cycling common in heat pump and furnace applications, providing the mechanical rotation support needed for 24/7 operation.

• Precision 3/4" Bore: Ensures a secure, slip-free fit on standard blower and motor shafts to eliminate vibration.
• OEM Compatibility: Specifically engineered for York and Johnson Controls equipment, maintaining factory specifications for load and speed.
• Reduced Friction Design: Lower rotational resistance minimizes the electrical load on the motor, extending the component lifecycle.
• High-Temperature Durability: Constructed to handle the internal temperatures of air handlers and furnace assemblies without grease breakdown.

Common Questions

Is this bearing compatible with 3/4" shaft blower motors?
Yes, as long as the motor is part of a supported York or Johnson Controls assembly. Always verify the shaft tolerance and housing diameter against the S1-026-12850-000 specifications before installation.

Does this part include the isolator?
Many technician kits for the S1-026-12850-000 include the necessary isolator for dampening vibration, which is a critical step when replacing bearings in older air handlers.

Can I use this for both fan and inducer motors?
This specific 3/4" bearing is sized for larger blower fan assemblies. Inducer motors often use smaller diameter bearings, so checking the part number on the motor identification plate is highly recommended.
