we see these bearings most often used to mitigate shaft runout and reduce the harmonic vibration that leads to premature motor winding failure

sharing the same 1" pipe size and 24VDC electrical requirements

ensuring the sensor bulb makes full contact for reliable domestic hot water regulation

Suction line valves (low side) typically require larger diameters

Facilitates sensor maintenance and hot-swapping without depressurizing the hydronic loop

York S1-324-36073-346 ECM Motor 322027-701 we see these bearings mostThe York S1 324 36073 346 ECM Motor is a high efficiency 1 2 HP blower motor designed specifically for compatible York, Coleman, and Luxaire HVAC systems.
