Bunting Bearing 06BU04 Sleeve Bearing 3/8 in Id Steel

Product Description

The BUNTING BEARING 06BU04 is a plain-bore sleeve bearing manufactured from steel, designed to provide low-friction radial support in rotating shaft applications. It features a 3/8-inch inner diameter, a 15/32-inch outer diameter, and an overall length of 1/4 inch. With a maximum pressure-velocity (PV) rating of 51,000 psi, this bearing is built to handle demanding load and speed conditions. Sleeve bearings of this type are installed by maintenance technicians, millwrights, and HVAC service professionals in motors, fans, and light machinery requiring reliable shaft support without rolling elements.

This bearing is suited for use in residential and light commercial equipment where compact, press-fit shaft support is needed. Its small footprint makes it appropriate for fractional-horsepower motors, blower assemblies, and similar rotating components. The plain bore design allows for straightforward insertion into a housing bore machined to the appropriate tolerance. Its rated temperature range of -328 degrees F to 536 degrees F makes it viable across a wide range of operating environments, from refrigeration-side applications to higher-temperature motor housings.

Compatibility

Designed as an OEM-style replacement sleeve bearing for fractional-horsepower motors, blower assemblies, and light rotating equipment requiring a 3/8-inch bore plain sleeve bearing.

Installation Notes

Installation is typically performed by qualified technicians or millwrights. De-energize all equipment and lock out power before replacing any bearing. Press-fit installation should be performed using appropriate arbor press tooling to avoid cocking the bearing in the housing bore. Inspect the housing bore and shaft for wear or damage before installing the replacement bearing.
