Browning 766558 Eccentric Locking Insert Bearing

Product Description

The BROWNING 766558 is an eccentric locking insert bearing designed for industrial and mechanical power transmission applications. Built around a 52100 steel insert and housed in a rubber grommet, this bearing features a 1 inch straight bore, a 2-17/32 inch outer diameter, and a 1 inch race width. It delivers a dynamic load capacity of 2,801 pounds and a static load capacity of 1,651 pounds. The nylon cage and rubber grommet housing make this unit well suited for applications requiring vibration dampening and reliable shaft retention. It is installed by maintenance mechanics and industrial technicians in rotating machinery and conveyor systems.

This insert bearing is appropriate for light to medium industrial equipment where eccentric locking collar retention is preferred over set-screw designs. The rubber grommet housing absorbs vibration and reduces noise transfer to the mounting structure. Typical installations include conveyor frames, agricultural equipment, fans, and light manufacturing machinery. It is rated to a maximum of 3,500 RPM, making it suitable for moderate-speed shaft applications. The RUBRE 100 series designation identifies this as a rubber-housed insert bearing intended for use in applications where a standard pillow block or flange housing is not required.

• Rated to 3,500 RPM maximum for moderate-speed applications
• 2,801 pound dynamic load capacity and 1,651 pound static load capacity

Compatibility

Designed as an OEM-style replacement or direct-fit insert bearing for applications requiring a 1 inch straight bore, eccentric locking type bearing in the RUBRE 100 series configuration.

Installation Notes

Installation should be performed by a qualified maintenance mechanic or millwright. De-energize and lock out the machine before removing the existing bearing or installing the replacement. Ensure the shaft diameter and surface finish are within specification before seating the bearing. Do not hammer directly on the bearing races during installation; use a proper bearing installation sleeve or press.
