Browning 767745 Pillow Block Bearing 1.25 Inch Bore Cast Iron

Product Description

The BROWNING 767745 is a cast iron pillow block bearing in the VPLS 100 Series, designed to support rotating shafts in fixed mounting applications across industrial and mechanical systems. It features a 1-1/4 inch straight bore with a set screw locking mechanism securing a 52100 bearing steel ball insert. The housing measures 6-3/16 inches in overall length and 3-5/32 inches in overall height. Static load capacity is rated at 2,567 pounds and dynamic load capacity at 4,381 pounds, making it suited for moderate-to-heavy radial load applications. Licensed millwrights, maintenance technicians, and industrial mechanics install this type of bearing during equipment builds and preventive maintenance programs.

This pillow block is appropriate for use in conveyor systems, fan shaft assemblies, pump drives, agricultural equipment, and general industrial machinery where a two-bolt, base-mounted bearing housing is required. The VPLS 100 Series is sized for 1-1/4 inch shaft diameters running at speeds up to 3,000 RPM. Mounting hole center-to-center spacing is 4-5/8 inches, and the base-to-center height is 1-9/16 inches, allowing straightforward layout on standard mounting plates or fabricated bases.

Compatibility

Designed as an OEM-style replacement or direct-fit pillow block bearing for industrial shaft assemblies requiring a 1-1/4 inch straight bore, two-bolt housing in the VPLS 100 Series configuration.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic. De-energize and lock out all power to the driven equipment before removing or installing any bearing assembly in accordance with OSHA lockout/tagout procedures. Ensure the shaft is clean and free of burrs before sliding the bearing into position, and torque set screws to the fastener manufacturer's specification using a calibrated hex key or torque wrench. Align the housing squarely on the mounting surface before tightening mounting bolts to prevent pre-loading the bearing and reducing service life.
