Browning 764061 Pillow Block Bearing 2-3/16 Inch Id

Product Description

The BROWNING 764061 is a VPB 200 Series pillow block bearing designed for air handling applications in HVAC and mechanical systems. It features a 2-3/16 inch bore diameter and a cast iron housing with a 52100 bearing steel insert, making it well suited for the sustained loads and rotational speeds common in fan and blower assemblies. The bearing carries a static load capacity of 6,601 pounds and a dynamic load capacity of 9,752 pounds, with a maximum rated speed of 2,500 RPM. An eccentric lock collar secures the bearing to the shaft without requiring a keyed bore. Licensed HVAC mechanics and millwrights are the typical installers for this class of component.

This pillow block is engineered for air handling unit (AHU) applications including belt-driven supply and return fans, blower wheel shafts, and similar rotating equipment in commercial and industrial HVAC systems. The two-bolt mounting configuration and 6-15/16 inch center-to-center bolt spacing suit standard AHU frame dimensions. The base-to-center height of 2-1/2 inches and overall height of 4-31/32 inches allow straightforward alignment with existing shaft centerlines during retrofit or replacement work. The straight bore accepts standard shafting without modification.

Compatibility

Designed as a direct replacement or service bearing for air handling unit fan shafts and blower assemblies requiring a 2-3/16 inch bore two-bolt pillow block in the VPB 200 Series. Consult OEM documentation to confirm mounting dimensions and shaft specifications before installation.

Installation Notes

Installation should be performed by a qualified millwright or licensed HVAC technician. De-energize and lock out the unit per OSHA lockout/tagout procedures before removing any rotating components. Ensure the mounting surface is flat and level before torquing the two mounting bolts to achieve proper housing alignment. Tighten the eccentric lock collar in the direction of shaft rotation and verify shaft runout and bearing alignment with a dial indicator before returning the unit to service.
