Greenheck 360422 Bearing

The Greenheck 360422 Bearing is a critical power transmission component designed for high-performance air handling applications. This PB3/4 pillow block bearing features a 3/4-inch bore diameter and utilizes a stamped steel housing with a zinc-plated finish for enhanced corrosion resistance in light-duty environments. Engineered for precision, the Greenheck 360422 incorporates an eccentric locking collar to provide a secure, non-slip attachment to the fan shaft, minimizing vibration and ensuring concentric rotation. This OEM Greenheck replacement bearing is the professional standard for maintaining belt-drive centrifugal fans and blowers where smooth, quiet operation is non-negotiable. The internal ball bearing insert is permanently lubricated and equipped with single-lip NBR seals and slingers to protect against dust and debris infiltration. By replacing worn components with this 3/4 inch fan bearing, contractors can effectively restore system efficiency and prevent premature shaft wear in commercial HVAC equipment.

Key Benefits

• Precision Shaft Alignment: The spherical bearing seat allows for initial self-alignment, reducing swivel torque and preventing mechanical binding during startup.
• Durable Housing Construction: The two-piece zinc-plated stamped steel housing provides a lightweight yet rigid mounting base suitable for standard HVAC bolt patterns.
• Vibration Dampening: Specifically tested for "air handling quality" to ensure noise reduction and extended life cycles in high-RPM fan applications.
• Reliable Locking Mechanism: The eccentric collar provides superior holding power on the shaft compared to standard set screws, reducing the risk of fretting corrosion.

Common Questions

How do I ensure the eccentric collar is installed correctly?
Slide the Greenheck 360422 onto the shaft and rotate the collar in the direction of shaft rotation until it engages the inner race, then tighten the set screw to lock it in place.

Can this bearing be used in high-moisture environments?
While the zinc-plated housing offers moderate corrosion protection, this PB3/4 bearing is best suited for dry air handling units. For wash-down areas, consult our team for cast iron or stainless steel alternatives.

Is this a direct replacement for all Greenheck 3/4" shafts?
This is an OEM replacement part for specific light-duty fans. Always verify the bolt hole spacing and load requirements, as some high-horsepower blowers may require cast iron pillow blocks.
