Lau 38220401 Bearing
The Lau 38220401 Bearing is a professional-grade 5/8" shaft diameter pillow block sleeve bearing engineered for high-demand HVAC blower assemblies and air handling units. Featuring a two-bolt mounting flange with 3-1/2" centers, this unit is built with a re-oilable porous bronze bushing encased in a pressed steel ball unit. The heavy neoprene cushion provides critical vibration isolation and static-free operation, making it a preferred choice for technicians seeking to eliminate disruptive resonant noise in commercial and residential fan systems. Its self-aligning capability compensates for minor shaft deflections, reducing side-load stress and preventing premature sleeve bearing failure. Designed for efficiency, the interlocking steel housing ensures structural integrity during high-RPM cycles. This HVAC blower bearing is compatible with various Lau Industries fan components and is essential for maintaining proper axial and radial load distribution. For a complete overhaul, verified technicians often pair this with a thrust collar kit to maintain specific shaft positioning under continuous lateral pressure.
Key Benefits
- Vibration Dampening: Integrated heavy neoprene liner absorbs mechanical harmonics for quiet operation.
- Precision Alignment: Self-aligning pressed steel housing automatically adjusts to shaft misalignment issues.
- Thermal Efficiency: Re-oilable porous bronze bushing retains lubricant longer to minimize friction-induced heat.
- Universal Mounting: Standard two bolt mounting flange with 3-1/2" hole centers fits most industrial blower frames.
- Static Protection: Constructed to provide a static-free environment, preventing electrical arcing in sensitive fan assemblies.
Common Questions
What are the signs that a blower bearing needs replacement?
Technicians should look for excessive noise and vibration, grinding sounds during startup, or visible shaft play (clunking). Overheating at the bearing housing often indicates lubrication failure or premature wear of the bronze bushing.
Is the Lau 38220401 compatible with all 5/8" shafts?
While it fits any standard 5/8 inch shaft diameter, you must verify the 1-3/16" base-to-center height and 3-1/2" mounting bolt spacing to ensure total pillow block bearing alignment with the existing motor mount.
Does this bearing require a thrust collar?
In most blower applications where axial movement must be restricted, a separate thrust collar kit is required to lock the shaft position against the sleeve bearing surface.
