Browning 766184 VPB-220 Pillow Block Bearing 1.25in Cast Iron

Product Description

The BROWNING 766184 is the VPB-220 series pillow block bearing unit designed for industrial shaft support applications in rotating equipment. It houses a 52100 bearing steel ball insert with a 1.25-inch straight bore, secured by an eccentric lock collar. The cast iron housing provides rigid, vibration-resistant mounting across a wide range of mechanical drive systems. With a static load capacity of 3,493 pounds and a dynamic load capacity of 5,782 pounds, this unit is built for moderate-to-heavy radial loads. Licensed millwrights, maintenance mechanics, and industrial service technicians typically install this bearing in conveyor, fan, pump, and drive shaft applications.

The VPB-220 pillow block is suited for both light industrial and commercial mechanical systems requiring a two-bolt, base-mounted bearing block. It fits horizontal and low-angle shaft orientations where rigid housing is needed. The 5-inch center-to-center bolt spacing and 1-7/8-inch base-to-center height make it compatible with standard mounting plates and fabricated steel frames common in HVAC mechanical rooms, material handling equipment, and agricultural machinery. The eccentric locking design allows field adjustment of shaft position without specialty tooling.

Key Features

• 52100 bearing steel ball insert for durability under radial and light thrust loads
• Eccentric lock collar for secure shaft retention without keyways
• Cast iron housing rated for static loads up to 3,493 pounds and dynamic loads up to 5,782 pounds
• Two-bolt base mount with 5-inch hole center-to-center spacing
• Maximum rated speed of 4,000 RPM
• Straight bore at 1.25 inches for standard shaft fitment

Compatibility

Designed as an OEM-style replacement or new-installation pillow block bearing for industrial rotating equipment requiring a 1.25-inch straight bore, two-bolt base mount housing in the VPB 200 series configuration.

Installation Notes

Installation is performed by qualified millwrights or maintenance mechanics. De-energize and lock out all connected equipment before beginning shaft or bearing work, following OSHA lockout/tagout procedures. Ensure the mounting surface is flat and the bolt holes are properly aligned before torquing fasteners to avoid housing distortion. The eccentric collar should be tightened in the direction of shaft rotation to prevent backing off during operation.
