Lau 60331501 Bushing
The Lau 60331501 is a precision-engineered H Series Split Taper Bushing designed specifically for demanding HVACR applications requiring high torque transmission and reliable shaft mounting. This heavy-duty tapered hub features a 1 1/8" bore and an integrated 1/4" x 1/8" keyseat, ensuring a secure, non-slip connection between the motor shaft and rotating components such as centrifugal blowers or 24-inch to 48-inch fan propellers. The split-barrel design provides a superior concentric fit, distributing clamping force evenly across the shaft to minimize vibration and prevent premature bearing wear in high-static pressure systems.
Constructed from high-grade steel for industrial durability, this split taper bushing is widely utilized for blower wheel replacement and power transmission in commercial air handlers. The H-style geometry facilitates simplified installation and removal using standard cap screws, which act as jackscrews during disassembly to prevent damage to the hub or shaft. This component is essential for technicians performing HVAC motor shaft mounting where precise alignment and robust mechanical locking are critical for system efficiency and noise reduction.
Key Benefits- Optimized Power Transmission: The 1 1/8" bore and 1/4" keyway provide high-torque capacity for heavy fan loads.
- Vibration Dampening: Precision concentricity reduces shaft runout, extending the lifespan of motor bearings and belts.
- Field-Serviceable Design: Split-taper configuration allows for rapid removal without specialized pullers, even after long periods of operation.
- Broad Compatibility: Engineered to fit Lau H-style hubs and a wide range of industrial sheaves and propellers.
What is the recommended installation torque for this H-series bushing?
For standard H-series split taper bushings, cap screws should typically be tightened to 95 lb-in (approximately 8 lb-ft). Always use a torque wrench to prevent over-tightening, which can lead to flange breakage.
Do I need to lubricate the shaft or bushing before installation?
No. The split taper design relies on friction. Applying oil, grease, or anti-seize to the tapered surfaces or shaft can lead to over-stressing the material and eventual failure of the hub.
Can this bushing be used on a shaft without a keyway?
While the split taper provides significant clamping force, the 1/4" x 1/8" keyway is required for high-torque HVAC applications to ensure the Lau 60331501 does not slip during startup or peak operation.
