Browning 767917 Pillow Block Bearing 1-3/4 in Cast Iron

Product Description

The BROWNING 767917 is a cast iron pillow block bearing designed to support rotating shafts in stationary mounted applications. Based on the VPE-228 series, it features a 1-3/4 inch inside diameter bore and an eccentric lock collar for secure shaft retention. The bearing insert is manufactured from 52100 steel, a high-carbon chromium alloy widely used in rolling-element bearing applications for its fatigue resistance. With a static load capacity of 5,139 pounds and a dynamic load capacity of 7,901 pounds, this unit is suited for moderate-to-heavy duty industrial and mechanical systems. Licensed tradespeople and mechanical contractors install this component during equipment assembly or bearing replacement service.

This pillow block is appropriate for use in conveyor systems, fan shafts, pump drives, and similar rotating-equipment assemblies found in industrial, commercial, and mechanical plant environments. The two-bolt base mounting pattern with a 5-21/32 inch center-to-center spacing fits standard mounting plate layouts. The 2-1/8 inch base-to-center height positions the shaft centerline consistently above the mounting surface. Applications requiring 1-3/4 inch bore shaft support with eccentric locking in a compact cast iron housing are the primary target for this bearing unit.

Key Features

• 1-3/4 inch bore inside diameter with eccentric lock collar for positive shaft retention
• Cast iron housing for rigidity and resistance to deformation under load
• 52100 steel bearing insert for high fatigue resistance in rolling-element contact
• 5,139 pound static load capacity and 7,901 pound dynamic load capacity
• Two-bolt mounting base with 5-21/32 inch hole center spacing
• Overall assembled height of 4-1/4 inches with 2-1/8 inch base-to-center height

Compatibility

Designed as an OEM-style replacement or new-installation pillow block bearing for 1-3/4 inch diameter shafts requiring a two-bolt cast iron housing with eccentric lock in standard industrial mounting configurations.

Installation Notes

Installation is typically performed by qualified millwrights or mechanical technicians. De-energize and lock out all connected drive equipment before removing or installing bearing units. Ensure the mounting surface is flat and clean before securing the base bolts, and verify shaft alignment before final tightening of the eccentric lock collar. Do not exceed the rated static or dynamic load capacities for the application.
