Browning 765129 Pillow Block Bearing 2.25 in Id Cast Iron

Product Description

The BROWNING 765129 is a cast iron pillow block bearing designed to support rotating shafts in industrial and mechanical drive applications. It features a 2.25-inch bore and accepts a 52100 steel insert locked in place by an eccentric locking collar for reliable shaft retention under load. With a static load capacity of 8,150 pounds and a dynamic load capacity of 11,789 pounds, this unit handles demanding radial loads in conveyors, fans, pumps, and similar shaft-driven equipment. The overall height is 5.5 inches and the overall length is 9.5 inches. Licensed mechanics, millwrights, and industrial maintenance technicians are the primary installers for this type of bearing housing.

This pillow block is suited for use in both light industrial and heavy-duty mechanical systems where a two-bolt base mount is required. The 7-13/32-inch center-to-center mounting hole spacing and 2-11/16-inch base-to-center height allow for straightforward shaft alignment during installation. Typical applications include conveyor lines, agricultural equipment drives, pump bases, and ventilation fan assemblies where a bolt-down bearing housing with a standard bore size is specified.

Key Features

• 2.25-inch inside diameter accommodates standard shaft sizing common in industrial drive systems
• Eccentric lock collar provides positive shaft retention without set screws damaging the shaft surface
• 52100 steel bearing insert for high load capacity and wear resistance
• 8,150-pound static and 11,789-pound dynamic load capacities suited for heavy radial loads
• Cast iron housing for rigid, vibration-dampening mounting in demanding environments
• Two-bolt base mounting pattern with 7-13/32-inch hole center spacing for standard base plate layouts

Compatibility

Designed as an OEM-style replacement or direct-mount pillow block bearing for industrial shaft applications requiring a 2.25-inch bore two-bolt housing with eccentric locking collar.

Installation Notes

Installation should be performed by a qualified millwright or industrial maintenance technician. Ensure all power to the drive system is fully locked out and tagged out before removing or installing the bearing housing. Align the shaft carefully before fully tightening the base mounting fasteners, and seat the eccentric collar in the direction of shaft rotation to lock. Follow applicable ANSI and OSHA lockout/tagout procedures during service.
