Browning 730015 Pillow Block Bearing 3 Inch Type E

Product Description

The BROWNING 730015 is a Type E nonexpansion pillow block bearing designed for heavy-duty shaft support in industrial and mechanical drive applications. Built around a tapered roller bearing insert made from 52100 bearing steel, this unit handles radial and thrust loads with a straight bore measuring 3 inches in diameter. The cast iron housing provides rigidity and durability in demanding environments. With an overall length of 12 inches and a base-to-center height of 3.125 inches, this pillow block is suited for installations requiring a fixed bearing position. A two-bolt mounting pattern and set screw locking mechanism secure the unit firmly to the mounting surface. Maximum operating speed is 1500 RPM.

The BROWNING 730015 is used in industrial conveyor systems, material handling equipment, pump drives, fans, and other power transmission applications where a fixed, nonexpansion bearing mount is required. The Type E nonexpansion design is typically paired with an expansion-type bearing on the opposing shaft end to accommodate thermal shaft growth. This unit is appropriate for both new installations and direct replacement of worn or failed pillow block assemblies in comparable drive systems.

Key Features

• Tapered roller bearing insert for high radial and thrust load capacity
• 52100 bearing steel insert for wear resistance and long service life
• Cast iron housing rated for heavy-duty industrial use
• Straight bore with set screw locking for secure shaft engagement
• Two-bolt mounting configuration with 9.75 inches center-to-center bolt spacing
• Type E nonexpansion design for use as the fixed bearing point on a shaft

Compatibility

Designed as an OEM-style replacement or new-installation pillow block bearing in the PBE920 series, suitable for shafts with a 3 inch straight bore diameter in industrial power transmission applications.

Installation Notes

Installation is typically performed by a millwright or mechanical technician following standard power transmission practices. De-energize and lock out all power to the driven equipment before removing or installing the bearing unit. Ensure the mounting surface is flat and clean before torquing the mounting bolts, and align the shaft carefully to avoid imposing bending loads on the bearing insert. As a nonexpansion bearing, this unit should be paired with an expansion-type pillow block at the opposite end of the shaft to allow for thermal growth.
