York S1-029-20490-000 Bearing

The York S1-029-20490-000 is an OEM replacement bearing specifically engineered for high-demand HVAC blower motor assemblies and air handling units. Featuring a precision-ground 1-3/16" bore, this heavy-duty 3-bolt flange bearing provides critical support for fan shaft rotation, ensuring concentricity and reducing parasitic load on the motor. The triangular bracket configuration is designed for mounting surfaces where the shaft is perpendicular to the frame, managing both radial and moderate axial thrust. For commercial HVAC maintenance, technicians often find that replacing these flange mounted bearings restores system balance and eliminates the vibration common in aged York air handlers. Because performance depends on a tight tolerance fit, using genuine York parts is standard practice to maintain shaft integrity and prevent premature bearing housing wear. This unit includes a locking collar or set screw mechanism to secure the shaft, preventing slippage during high-RPM operations in constant-run fan applications.

• Precision 1-3/16" Bore: Ensures a secure, zero-play fit on standard blower shafts to eliminate shaft scoring.
• Durable 3-Bolt Housing: The triangular flange provides a stable mounting footprint that distributes bolt stress evenly across the bracket.
• OEM Performance Standards: Engineered to match original factory specifications for York HVAC equipment, preventing compatibility issues at the job site.
• Enhanced Vibration Dampening: High-quality ball bearing inserts reduce harmonic noise and mechanical resonance in air distribution systems.

• Is this bearing pre-lubricated? Yes, most York OEM bearings come factory-sealed with high-temperature grease, though some 3-bolt variants feature a grease zerk for field re-lubrication.
• Should I replace both bearings at once? As a best practice for HVAC blower repair, technicians should replace both the drive-end and non-drive-end bearings simultaneously to ensure even shaft loading.
• Does this include the locking collar? This assembly typically includes the necessary hardware to lock the bearing to the 1-3/16" shaft, maintaining the axial position.
