Boston Gear 35584 Flanged Sleeve Bearing 0.5 in Id Bronze

Product Description

The BOSTON GEAR 35584 is an oil-impregnated bronze flanged sleeve bearing designed for light-to-moderate load shaft support in rotating machinery. It features a plain bore with a 0.502-inch inside diameter and a 0.628-inch outside diameter, with an overall length of 1 inch. The integral flange measures 0.875 inches in outside diameter and 0.125 inches thick, providing a positive axial stop during installation. The sintered bronze construction retains lubricating oil within the porous matrix, eliminating the need for external lubrication in most service intervals. Maintenance technicians, millwrights, and HVAC equipment installers commonly specify this style of bearing for fan shafts, blower assemblies, and light-duty drive applications.

This bearing suits residential and light commercial equipment where a self-lubricating, press-fit bushing is required. Typical applications include fan and blower shaft support in furnaces, air handlers, and ventilation equipment, as well as general industrial machinery requiring a compact, maintenance-friendly sleeve bearing. It complies with SAE 20 (ISO 68) and SAE 30 (ISO 100) lubricant standards, confirming compatibility with standard mineral oil systems. The flanged design locates axially against a housing shoulder without additional hardware.

Key Features

• Oil-impregnated sintered bronze construction provides self-lubrication without external grease fittings
• Maximum pressure-velocity rating of 50000 psi supports moderate radial load applications
• Integral flange (0.875 inches OD, 0.125 inches thick) provides positive axial positioning in the housing
• Plain bore accepts standard 0.5-inch shafts with minimal clearance
• Meets SAE 20 (ISO 68) and SAE 30 (ISO 100) lubricant standards
• Compact overall length of 1 inch fits space-constrained housings

Compatibility

Designed as an OEM-style replacement flanged sleeve bearing for fan shafts and light-duty rotating equipment requiring a 0.5-inch bore, 0.625-inch outside diameter, and a 1-inch overall length in oil-impregnated bronze.

Installation Notes

Installation is typically performed by a millwright, HVAC technician, or qualified maintenance professional. Power down and lock out the equipment before removing the worn bearing. Press the bearing into its housing bore using an arbor press or a properly sized driver that contacts the outer diameter only - never drive against the flange face or bore surface. Verify shaft and housing dimensions before installation to ensure proper interference fit and running clearance.
