Browning 730020 Type E 4-bolt Flange Bearing 1.25in Bore

Product Description

The BROWNING 730020 is a Type E 4-bolt flange bearing designed for mounted tapered roller bearing applications in industrial and mechanical drive systems. With a maximum bore diameter of 1.25 inches and an overall length of 3.75 inches, this bearing unit provides rigid shaft support at fixed mounting points. The cast iron housing offers durability in demanding environments. A 3/8-inch bolt size and 2.875-inch distance between mounting hole centers make it straightforward to position on standard equipment frames. Licensed millwrights, maintenance mechanics, and industrial service technicians are the primary installers of this type of bearing unit.

This bearing is suited for use in conveyor systems, fan shafts, pump drives, and general power transmission equipment where a four-bolt flange mount is required. The tapered roller design handles both radial and axial loads, making it a dependable choice for moderate-to-heavy duty rotating shaft applications. It is commonly installed in manufacturing, agricultural, and HVAC air-handling equipment that uses belt or direct-drive configurations requiring a rigid flange-mount bearing housing.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic. De-energize and lock out all power to the drive system before removing or installing any bearing unit. Ensure the mounting surface is clean and flat before torquing flange bolts, and verify shaft alignment after installation to avoid premature bearing wear. Follow applicable ANSI and OSHA lockout/tagout procedures throughout service.
