Browning 766553 Set Screw Insert Bearing 1 in Bore

Product Description

The BROWNING 766553 is a set screw locking insert bearing designed for use in rotating shaft applications across industrial and mechanical systems. Sold under the RUBRS-116 series designation, this bearing features a 1-inch straight bore and a 2-17/32-inch outer diameter. The insert is manufactured from 52100 steel, a through-hardened alloy common in precision bearing applications. Dynamic load capacity is rated at 2,801 pounds and static load capacity is 1,651 pounds, making it suitable for moderate-to-heavy radial load conditions. The rubber grommet housing provides vibration dampening and helps protect the bearing from minor misalignment and shock loading in service.

This insert bearing is intended for use in conveyor systems, agricultural equipment, material handling machinery, and general industrial drive assemblies wherever a set screw locking style is appropriate. The RUBRS 100 series is commonly installed in applications requiring a rubber-housed bearing unit that can absorb vibration and reduce transmitted noise. Licensed millwrights, maintenance technicians, and industrial mechanics are the typical installers. The bearing suits both OEM build applications and field replacement work on existing machinery with 1-inch shaft diameters.

Key Features

• 52100 steel insert for through-hardened durability under radial load
• Rubber grommet housing absorbs vibration and dampens shock loading
• Set screw locking mechanism secures the bearing to a 1-inch straight bore shaft
• 2,801-pound dynamic load capacity and 1,651-pound static load capacity
• Maximum rated speed of 3,500 RPM
• 1-inch race width provides stable contact geometry across the shaft

Compatibility

Designed as a replacement or OEM-style insert bearing for applications requiring a 1-inch straight bore, set screw locking, rubber grommet housed unit within the RUBRS 100 series.

Installation Notes

Installation should be performed by a qualified millwright or industrial maintenance technician. De-energize and lock out the drive system before removing the existing bearing or mounting the replacement unit. Set screws should be tightened with the appropriate hex key to the shaft flat or turned surface per standard mechanical assembly practice — do not overtighten to the point of shaft deformation. Verify shaft diameter and surface finish are within tolerance before pressing or sliding the insert onto the shaft.
