Browning 767335 Pillow Block Bearing 2-3/16 in Cast Iron

Product Description

The BROWNING 767335 is a cast iron pillow block bearing designed to support rotating shafts in industrial and mechanical drive applications. This unit accepts a 2-3/16 inch bore and features an eccentric lock collar for secure shaft positioning without set screws. The bearing insert is manufactured from 52100 steel, a high-carbon chromium alloy commonly specified for bearing applications requiring good fatigue resistance. With a static load capacity of 6,601 pounds and a dynamic load capacity of 9,752 pounds, the 767335 is suited for moderate-to-heavy radial load conditions. Licensed millwrights, maintenance mechanics, and industrial equipment technicians typically install and service this type of unit.

This pillow block is used in conveyor systems, fan and blower assemblies, pump drives, and general power transmission equipment across industrial and commercial facilities. The two-bolt mounting base with 6-15/16 inch center-to-center spacing simplifies installation on standard mounting surfaces. The base-to-center height of 2-1/2 inches and overall length of 8-13/16 inches allow straightforward shaft alignment in typical drive train configurations. The overall height of 4-31/32 inches suits enclosed or open-frame equipment frames where vertical clearance is a design consideration.

Compatibility

Designed as an OEM-style replacement or new-installation pillow block bearing for industrial power transmission systems requiring a 2-3/16 inch bore, two-bolt cast iron housing, and eccentric locking collar.

Installation Notes

Installation is typically performed by licensed millwrights or qualified maintenance technicians following OSHA lockout/tagout procedures before any shaft or bearing work. The mounting surface should be clean, flat, and properly torqued to fastener specifications supplied by the equipment manufacturer. Align the bearing housing with the shaft centerline before tightening the eccentric lock collar to prevent pre-loading the insert. Verify lubrication type and re-lubrication intervals according to the equipment OEM guidelines for the operating speed and load conditions.
