This bearing features a 75mm bore, 160mm outer diameter, and 37mm width, placing it in the 6315 series of single-row deep groove bearings. It is fitted with low-torque light contact seals on both sides and carries a C3 internal clearance designation, making it suitable for applications with higher operating temperatures or press-fit installations where thermal expansion is a concern. Licensed technicians and equipment service professionals install this bearing class during motor and drivetrain rebuilds.\u003c\/p\u003e\u003cp\u003eThe C3 clearance rating provides greater than standard internal play between the balls and raceways, which reduces the risk of bearing preload buildup in elevated-temperature environments. The light contact rubber seals retain grease and exclude contaminants without generating significant drag, allowing this bearing to operate efficiently in motor-driven equipment. Typical applications include belt-drive blower motors, centrifugal pump shafts, fan assemblies, and industrial gearbox input shafts where moderate speeds and radial loads are present.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eC3 internal clearance for thermally demanding or interference-fit installations\u003c\/li\u003e\n\u003cli\u003eDual-sided light contact seals retain lubrication and resist contamination ingress\u003c\/li\u003e\n\u003cli\u003eLow-torque seal design minimizes frictional resistance during operation\u003c\/li\u003e\n\u003cli\u003e75mm bore accommodates standard NEMA and IEC motor shaft sizes in this load class\u003c\/li\u003e\n\u003cli\u003eSingle-row deep groove geometry handles combined radial and moderate axial loads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct OEM-style replacement for 6315-2RS C3 class deep groove ball bearings used in industrial motors, HVAC blower assemblies, and pump drive shafts requiring a 75mm bore and C3 clearance specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician. Always de-energize and lock out the equipment before removing the shaft assembly. Use a bearing press or appropriate driver tool to seat the bearing squarely against the housing shoulder — never strike the bearing directly with a hammer. Consult the equipment manufacturer's service documentation for housing fit tolerances before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Series\u003c\/strong\u003e: 6315\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 75mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 160mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 37mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Clearance\u003c\/strong\u003e: C3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Type\u003c\/strong\u003e: Light Contact Seal, Both Sides (2RD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Torque\u003c\/strong\u003e: Low\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Deep Groove Ball Bearing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KOYO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KOYO6315-2RDC3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KOYO","offers":[{"title":"Default Title","offer_id":51468524486962,"sku":"KOYO6315-2RDC3","price":200.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945019.png?v=1783916348","url":"https:\/\/voomisupply.com\/products\/koyo-koyo6315-2rdc3-deep-groove-ball-bearing-c3","provider":"Voomi Supply","version":"1.0","type":"link"}
