Browning 767583 Pillow Block Bearing 1-3/16 in Id Cast Iron

Product Description

The BROWNING 767583 is a two-bolt pillow block bearing in the VPS 100 Series, designed to support rotating shafts in industrial and mechanical drive applications. The bearing features a 1-3/16 inch straight bore and a 52100 bearing steel insert secured by a set screw locking mechanism. It carries a static load capacity of 2,567 pounds and a dynamic load capacity of 4,381 pounds, making it suited for moderate-to-heavy radial load conditions. The cast iron housing provides rigid support and resists deflection under load. This unit is installed by millwrights, maintenance mechanics, and industrial technicians working on conveyor systems, fans, pumps, and general power transmission equipment.

The BROWNING 767583 fits applications requiring a standard two-bolt pillow block with a 1-3/16 inch shaft diameter. It is commonly used in conveyor drives, agricultural equipment, material handling systems, and HVAC fan assemblies where reliable shaft support is needed. The 4-23/32 inch center-to-center bolt spacing and 1-11/16 inch base-to-center height suit standard mounting plates and channel frames found in these installations. Maximum operating speed is rated at 3,000 RPM.

Key Features

• 1-3/16 inch straight bore accepts standard shaft diameters without machining
• 52100 bearing steel insert for high hardness and fatigue resistance under radial load
• Set screw locking type secures the bearing insert to the shaft
• Cast iron housing resists deformation and provides stable shaft alignment
• 2,567 lb static and 4,381 lb dynamic load capacities for moderate-to-heavy duty use
• Two-bolt mounting pattern with 4-23/32 inch hole centers simplifies installation on standard frames

Compatibility

Designed as an OEM-style replacement pillow block bearing for applications requiring a two-bolt, 1-3/16 inch bore unit in the VPS 100 Series.

Installation Notes

Installation should be performed by a qualified mechanic or millwright. Disconnect and lock out all power to the drive system before removing or installing any bearing. Align the pillow block carefully to the shaft centerline before tightening mounting hardware to avoid preloading the bearing. Set screws should be tightened to the shaft with the appropriate hex key; do not over-tighten, as this can damage the shaft or bearing insert.
