Browning 765811 Pillow Block Bearing 1-7/16 in Air Handling

Product Description

The BROWNING 765811 is a two-bolt pillow block bearing designed for air handling applications in commercial and industrial HVAC systems. Built around a 1-7/16 inch bore, this unit houses a 52100 bearing steel ball insert secured by a set screw lock type. The cast iron housing delivers the structural rigidity required in fan shaft and blower wheel assemblies. Static load capacity is rated at 3,493 pounds and dynamic load capacity at 5,782 pounds, making it well-suited for continuous-duty fan and blower service. Maximum speed is rated at 4,000 RPM. Mechanical contractors and HVAC technicians install this bearing during new equipment builds and replacement service on air handling units.

This pillow block bearing is used in air handling units, fan coil assemblies, centrifugal blowers, and similar rotating equipment found in commercial and light industrial settings. The straight bore and set screw locking design accommodate standard-diameter fan shafts and allow for straightforward shaft positioning during installation. The VPS 200 series construction is engineered for the vibration and load cycles typical of air handling fan applications. Contractors replacing worn or failed bearings on AHU fan decks will find the mounting footprint and bore size directly relevant to common shaft configurations in this class of equipment.

Compatibility

Designed as an OEM-style replacement pillow block bearing for two-bolt air handling fan shaft applications requiring a 1-7/16 inch bore and 5 inch bolt hole center-to-center spacing.

Installation Notes

Installation should be performed by a licensed mechanical contractor or qualified HVAC technician. De-energize and lock out the fan motor and disconnect all power before removing the existing bearing or working on the shaft assembly. Ensure the shaft and housing mounting surfaces are clean and free of debris before seating the bearing. Set screws should be tightened to the shaft per the manufacturer torque specification on the bearing insert documentation; do not over-tighten in a way that deforms the shaft.
