Lau 38244901 Bearing
The Lau 38244901 1 inch shaft bearing is a critical replacement component designed for high-performance blower assemblies in residential and commercial furnaces and air handlers. This oil-type sleeve bearing features a 1-inch bore to accommodate standard motor shafts and an 1 27/32 inch outside diameter (OD), measured over the integrated rubber insulator. Engineered for quiet blower operation, the heavy neoprene conductive rubber insulator acts as a vibration dampener and static-free mounting interface, ensuring the unit sits firmly within a spider-type bracket or 1-inch bearing housing. The internal assembly utilizes sintered bronze bushings pressed into steel caps, providing a porous surface that maintains a consistent hydrodynamic oil film. While these units are factory-lubricated, veteran technicians recommend re-lubricating with SAE 20 or 30 non-detergent oil upon installation to ensure the wicking material is fully saturated. To maintain proper axial positioning, these Lau replacement bearings typically require a thrust collar kit for secure shaft alignment in belt-drive or direct-drive HVAC applications.
Key Benefits- Self-aligning design compensates for minor shaft misalignments, reducing wear on the motor and blower wheel.
- Sintered bronze construction allows for self-oiling via drive-type oil cups and internal wicking for extended service intervals.
- Neoprene insulator cushion provides essential vibration isolation to eliminate resonant noise in the ductwork.
- Standardized 1-27/32" OD ensures compatibility with most 9-inch, 10-inch, and 12-inch Lau blower housings.
What oil should be used for maintenance?
Use a high-quality SAE 20 or 30 weight non-detergent oil. Avoid multi-viscosity motor oils or solvents like WD-40, which can degrade the wicking and lead to premature seizing.
Does this bearing include the thrust collars?
No, this specific cartridge bearing requires a separate thrust collar kit to prevent lateral shaft movement during high-velocity rotation.
How do I measure the OD correctly?
The 1 27/32" measurement is taken across the outermost surface of the rubber insulator. If you are replacing a bearing without the cushion, the steel housing diameter will be smaller.
