Browning 767880 Pillow Block Bearing 1-3/4 Inch Id Cast Iron

Product Description

The BROWNING 767880 is a two-bolt pillow block bearing in the VPS 200 Series, designed for shaft support in industrial and mechanical drive applications. It houses a ball bearing insert made from 52100 bearing steel, secured by a set screw locking mechanism on a 1-3/4 inch straight bore. The cast iron housing measures 7-3/8 inches overall length and 4-1/4 inches overall height, with a static load capacity of 5,216 pounds and a dynamic load capacity of 7,889 pounds. Maximum operating speed is 3,000 RPM. Mechanical maintenance technicians and millwrights are the typical installers.

This pillow block bearing is suited for conveyor systems, fan shaft assemblies, pump drives, and general industrial machinery where a rigid, two-bolt mounted bearing support is required. The VPS 200 Series is a standard industrial pillow block configuration commonly found in light-to-medium duty rotating equipment in manufacturing, HVAC mechanical rooms, and process industries. The 1-3/4 inch straight bore accommodates standard shaft diameters in this class of equipment.

Key Features

• 1-3/4 inch straight bore with set screw locking for positive shaft retention
• 52100 bearing steel insert for durability under radial and axial loads
• Cast iron housing resists deformation under sustained static and dynamic loads
• 5,216 pound static load capacity and 7,889 pound dynamic load capacity
• 3,000 RPM maximum speed rating for compatibility with standard motor-driven applications
• Two-bolt mounting with 5-21/32 inch center-to-center spacing for straightforward alignment

Compatibility

Designed as an OEM-style replacement or direct installation pillow block bearing for industrial shaft support applications requiring a two-bolt, 1-3/4 inch bore housing in the VPS 200 Series configuration.

Installation Notes

Installation is typically performed by a millwright or mechanical technician. De-energize and lock out all power to the driven equipment before removing or installing any bearing assembly per OSHA lockout/tagout requirements. Ensure the mounting surface is flat and clean before torquing the two mounting bolts, and verify shaft alignment before tightening the set screws to avoid premature bearing wear. Do not use impact tools directly on the bearing housing during installation.
