Browning 766189 Pillow Block Bearing 1-11/16 Inch Bore

Product Description

The BROWNING 766189 is a two-bolt pillow block bearing in the VPB 200 Series, designed to support rotating shafts in industrial and mechanical drive applications. The unit houses a ball bearing insert made from 52100 bearing steel and is enclosed in a cast iron housing. The straight bore measures 1-11/16 inches in diameter and accepts shafts locked in place via an eccentric locking collar. Static load capacity is rated at 5,216 pounds and dynamic load capacity at 7,889 pounds, making this unit suitable for moderate-to-heavy radial load applications across a wide range of industrial machinery.

This pillow block is commonly installed on conveyor systems, agricultural equipment, material handling machinery, and general industrial drive trains where a fixed shaft-support point is required. The two-bolt base mount pattern with 5-21/32-inch center-to-center spacing allows straightforward bolt-down installation on steel or fabricated frames. With a maximum rated speed of 3,000 RPM, it accommodates a broad range of low-to-moderate speed shaft applications. Installation is typically performed by millwrights, maintenance technicians, or mechanical contractors during new equipment builds or bearing replacement service.

Key Features

• 1-11/16 inch straight bore with eccentric locking collar for positive shaft retention
• 52100 bearing steel insert provides high hardness and fatigue resistance under load
• Cast iron housing resists deformation under sustained radial and static loads
• 5,216 lb static and 7,889 lb dynamic load ratings for moderate-to-heavy duty service
• 3,000 RPM maximum speed suits low-to-moderate speed drive applications
• Two-bolt mounting pattern simplifies installation and alignment on frame structures

Compatibility

Designed as an OEM-style replacement or new-installation pillow block bearing for industrial shaft-support applications requiring a 1-11/16 inch bore, two-bolt base mount, and eccentric locking collar within the VPB 200 Series configuration.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. De-energize and lock out all associated drive equipment before handling or mounting the bearing. Ensure the mounting surface is flat and that both bolt holes are aligned to the 5-21/32-inch center-to-center dimension before torquing fasteners. Tighten the eccentric locking collar in the direction of shaft rotation to secure the bore; do not overtighten or impact-drive the collar tab.
