Browning 767660 Pillow Block Bearing 1.5 in Cast Iron

Product Description

The BROWNING 767660 is a cast iron pillow block bearing designed to support rotating shafts in industrial and mechanical drive applications. It accepts a 1.5 inch inside diameter shaft and delivers a static load capacity of 4,467 pounds and a dynamic load capacity of 7,340 pounds. The bearing insert is manufactured from 52100 steel, a high-carbon chromium alloy widely used for rolling element bearings. Shaft retention is handled by an eccentric locking collar. This unit is suited for conveyor systems, fans, pumps, and general power transmission equipment where a two-bolt pillow block mount is required.

This pillow block is used in commercial and industrial installations where a fixed-position mounted bearing is needed along a shaft. The 5.375 inch distance between mounting hole centers and 1.9375 inch base-to-center height fit standard pillow block mounting footprints. The 3.9375 inch overall height and 7.125 inch overall length accommodate equipment frames sized for this bearing class. Millwrights, maintenance technicians, and mechanical contractors handle this type of installation in manufacturing, agricultural, and HVAC blower drive contexts.

Key Features

• 1.5 inch bore accepts standard mid-range shaft diameters
• Static load capacity of 4,467 pounds and dynamic load capacity of 7,340 pounds
• 52100 steel bearing insert for durability under radial and axial loading
• Eccentric collar locking mechanism for positive shaft retention
• Cast iron housing provides rigidity and resistance to shock loading
• Two-bolt base mount with 5.375 inch center-to-center hole spacing

Compatibility

Designed as an OEM-style replacement or direct-fit pillow block bearing for two-bolt mounted shaft applications requiring a 1.5 inch bore, cast iron housing, and eccentric collar locking in industrial power transmission systems.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. De-energize and lock out all power to the drive system before removing the existing bearing or mounting this unit. Align the shaft carefully before tightening the eccentric collar to avoid preloading the bearing. Verify that mounting surfaces are flat and fasteners are torqued according to the equipment manufacturer's specifications.
