With a 0.503 inch bore, 0.628 inch outside diameter, and 0.5 inch overall length, this plain bore bearing delivers self-lubricating performance through its porous bronze construction. The material absorbs and retains oil, releasing it continuously at the bearing surface during operation. Rated to a maximum pressure-velocity (PV) value of 50,000 psi, it handles demanding load-speed combinations without requiring external lubrication in most service intervals. Licensed HVAC techs, millwrights, and maintenance professionals install this type of bearing in motors, fans, pumps, and general rotating equipment.\u003c\/p\u003e\u003cp\u003eThis sleeve bearing suits residential and light commercial mechanical applications where a compact, self-lubricating plain bearing is required. Typical installations include small electric motor shafts, blower assemblies, and fan shaft support points. The 0.5 inch bore fits standard half-inch shaft diameters commonly found in HVAC blower motors and pump assemblies. Its compact 0.5 inch length fits tight axial spaces where larger flanged or housed bearings are not practical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOil impregnated bronze construction provides continuous self-lubrication without grease fittings\u003c\/li\u003e\n\u003cli\u003ePlain bore design accepts standard 0.5 inch diameter shafts\u003c\/li\u003e\n\u003cli\u003eMaximum PV rating of 50,000 psi suits moderate load and speed applications\u003c\/li\u003e\n\u003cli\u003eMeets SAE 20 (ISO 68) and SAE 30 (ISO 100) lubrication standards\u003c\/li\u003e\n\u003cli\u003eCompact 0.5 inch overall length fits tight axial clearances\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.013 pounds for easy handling and installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement sleeve bearing for rotating shaft applications requiring a 0.5 inch bore, 0.625 inch outside diameter, and 0.5 inch overall length plain bronze bearing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a qualified millwright, HVAC technician, or mechanical maintenance professional. Always de-energize and lock out the equipment before removing or installing bearings. Press-fit the bearing into the housing bore using an appropriate bearing press or driver sized to the outside diameter  -  do not strike the bearing face directly with a hammer. Verify shaft and housing tolerances are within manufacturer specifications before final assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.503 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.628 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Oil Impregnated Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Type\u003c\/strong\u003e: Plain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLubricant Type\u003c\/strong\u003e: Oil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure x Velocity (PV)\u003c\/strong\u003e: 50,000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE 20 (ISO 68), SAE 30 (ISO 100)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.013 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BOSTON GEAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 34720\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOSTON GEAR","offers":[{"title":"Default Title","offer_id":67912181088562,"sku":"34720","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eaa1135484e321eb33037784823dc8d2.jpg?v=1791229001","url":"https:\/\/voomisupply.com\/products\/boston-gear-34720-sleeve-bearing-oil-impregnated-bronze","provider":"Voomi Supply","version":"1.0","type":"link"}
