Browning 730007 PBE920X2 Pillow Block 2in Id Cast Iron

Product Description

The BROWNING 730007 is a Type E nonexpansion pillow block bearing unit in the PBE920 series, built for heavy-duty shaft support in industrial and mechanical drive applications. The housing is cast iron with a 52100 bearing steel tapered roller insert. It accepts a 2-inch bore straight shaft secured by a set screw lock. The unit measures 8.875 inches overall length with a 4.5-inch height and a base-to-center distance of 2.25 inches. Rated to 2000 RPM, it is sized for demanding power transmission loads where a rigid, nonexpansion mounting point is required. Licensed HVAC, mechanical, and industrial maintenance technicians regularly specify this type of unit for fan shafts, conveyor drives, and blower assemblies.

This pillow block is suited for industrial machinery, commercial HVAC fan decks, conveyor systems, and similar rotating equipment where a two-bolt, nonexpansion mount is appropriate. The PBE920X2 designation identifies the series and 2-inch bore size. Mounting bolt holes are centered 7.25 inches apart, with a minimum distance between mounting holes of 6.1875 inches. The tapered roller insert provides strong radial and thrust load capacity compared to a standard ball insert, making it a common choice in higher-load, moderate-speed applications.

Key Features

• Type E nonexpansion pillow block design — provides a fixed shaft position at the mounting point
• Tapered roller bearing insert for combined radial and axial load handling
• 52100 bearing steel insert housed in a cast iron body for durability
• Set screw shaft lock on a straight 2-inch bore — no adapter sleeve required
• Two-bolt mounting with 7.25-inch bolt hole center-to-center spacing
• 2000 RPM maximum rated speed

Compatibility

Designed as an OEM-style replacement or direct installation unit for machinery requiring a two-bolt, Type E nonexpansion pillow block with a 2-inch straight bore in the PBE920 series.

Installation Notes

Installation is typically performed by industrial maintenance technicians or mechanical contractors. Shut down and lock out the drive system before removing or installing any bearing unit. Ensure the mounting surface is flat and clean before seating the housing to prevent misalignment stress on the insert. Set screws should be tightened against a clean, undamaged shaft surface; do not install on a shaft that is corroded, undersize, or out of round.
