Boston Gear 35560 Flanged Sleeve Bearing 3/8 in Id Bronze

Product Description

The BOSTON GEAR 35560 is a flanged sleeve bearing manufactured from oil-impregnated bronze, designed for light-to-medium load rotary and oscillating shaft applications. The plain bore measures 0.377 inches ID and 0.502 inches OD, with an overall length of 1.25 inches. The flange extends to 0.6875 inches OD with a thickness of 0.09375 inches, providing a positive axial stop for shaft positioning. The porous bronze construction retains lubricant within the material, reducing the need for external re-lubrication in steady-state service. This bearing is typically installed by millwrights, maintenance mechanics, and OEM equipment assemblers working on light industrial and commercial machinery.

This bearing suits applications where a self-lubricating, press-fit sleeve is required in housings with a counterbore flange seat. Typical use cases include small electric motors, conveyor systems, pumps, fans, and general rotating equipment operating under moderate load and speed conditions. The flanged design simplifies axial positioning during assembly without requiring additional hardware. Rated to a maximum pressure times velocity (PV) value of 50,000 psi, it performs reliably in applications with controlled shaft speeds and radial loads. SAE 20 (ISO 68) and SAE 30 (ISO 100) oil grades are the specified lubricant standards for this bearing.

Key Features

• Oil-impregnated bronze construction provides built-in lubrication for extended service intervals
• Flanged design with 0.6875-inch flange OD enables positive axial location in counterbored housings
• Maximum PV rating of 50,000 psi supports moderate-load rotating and oscillating applications
• Plain bore at 0.377 inches ID accommodates 3/8-inch nominal shafting
• Meets SAE 20 (ISO 68) and SAE 30 (ISO 100) lubrication standards
• Compact 1.25-inch overall length suits space-constrained equipment assemblies

Compatibility

Designed as an OEM-style replacement or service part for equipment requiring a flanged sleeve bearing with a 3/8-inch bore, 1/2-inch OD, and 1-1/4-inch overall length in oil-impregnated bronze.

Installation Notes

Installation is typically performed by qualified maintenance mechanics or equipment assemblers. Press the bearing into the housing bore using an arbor press and a properly sized driver that contacts the outer diameter only - never drive against the flange face alone. Ensure the housing bore is clean and sized to the correct interference fit before installation. Shaft and housing surfaces should be inspected for wear or damage prior to fitting the new bearing.
