Boston Gear 13573 Sleeve Bearing Oil Impregnated Bronze

Product Description

The BOSTON GEAR 13573 is an oil-impregnated bronze sleeve bearing designed for light-duty rotational and sliding shaft applications. The plain bore design accepts a 0.252-inch inner diameter shaft and measures 0.314 inches outer diameter with an overall length of 0.5 inches. Constructed from SAE-grade oil-impregnated bronze, this bushing is self-lubricating under normal operating conditions, reducing maintenance requirements in assemblies where relubrication access is limited. It carries a maximum pressure-velocity rating of 50,000 psi-ft/min, making it suitable for moderate-load, moderate-speed shaft support. Maintenance technicians and equipment rebuilders install these bearings in motors, gear drives, and light machinery.

This sleeve bearing is used in residential and commercial equipment where a compact, self-lubricating plain bore bushing is required. Typical applications include small electric motor shaft support, pump assemblies, conveyor components, and gear drive housings. The 0.5-inch overall length suits installations with tight axial space constraints. Lubricant compatibility follows SAE 20 (ISO 68) and SAE 30 (ISO 100) oil standards, supporting systems where periodic oil-bath or wick lubrication supplements the impregnated supply.

Key Features

• Oil-impregnated bronze construction provides self-lubrication under normal load cycles
• Plain bore design with 0.252-inch ID for precise shaft fit
• Maximum pressure-velocity rating of 50,000 psi for moderate-duty service
• Compatible with SAE 20 (ISO 68) and SAE 30 (ISO 100) lubricant standards
• Compact 0.5-inch overall length suits space-restricted housings

Compatibility

Designed as an OEM-style replacement sleeve bearing for light-duty rotating equipment requiring a plain bore, oil-impregnated bronze bushing with a 0.25-inch shaft bore.

Installation Notes

Installation is typically performed by maintenance technicians or equipment rebuilders using a bearing press or arbor press to seat the bushing flush and square within the housing bore. De-energize and lock out all power to the equipment before removing the worn bearing. Avoid hammering directly on the bearing face, as this can distort the bore. Verify shaft-to-bore clearance after installation to confirm smooth rotation without binding.
