Browning 767881 Pillow Block Bearing 1-15/16 in Bore

Product Description

The BROWNING 767881 is a two-bolt pillow block bearing unit in the VPS 200 series, designed for industrial shaft support applications. It features a 1-15/16 inch straight bore with a set screw lock type and houses a 52100 bearing steel ball insert inside a cast iron housing. With a static load capacity of 5,216 pounds and a dynamic load capacity of 7,889 pounds, this unit is built for moderate-to-heavy radial load service. Rated to a maximum of 3,000 RPM, it suits a wide range of rotating equipment found in manufacturing, material handling, and HVAC fan drive systems. Licensed millwrights, industrial mechanics, and HVAC technicians are the typical installers.

The 767881 pillow block is suited for mounting on flat surfaces where a two-bolt footprint is required. The 6-15/16 inch center-to-center distance between mounting holes accommodates standard machine frames and equipment bases. The 2-1/2 inch base-to-center height positions the shaft centerline for common drive configurations. It is appropriate for use in conveyor systems, blower assemblies, fan shafts, and similar rotating equipment in both commercial and light industrial settings. The straight bore accommodates standard shaft tolerances when properly locked with the included set screw interface.

Compatibility

Designed as an OEM-style replacement or direct-install pillow block bearing for industrial rotating equipment requiring a two-bolt, 1-15/16 inch bore unit in the VPS 200 series footprint.

Installation Notes

Installation is typically performed by a licensed industrial mechanic or millwright. Before mounting, de-energize and lock out the drive equipment per OSHA lockout/tagout procedures. Ensure the mounting surface is clean, flat, and free of burrs before torquing fasteners. Set screw locking should be performed with the shaft properly aligned to avoid inducing bearing preload; do not over-tighten the set screws beyond the fastener specification for the screw size used.
