It features a 60 mm bore, 130 mm outer diameter, and 31 mm width. The bearing uses light contact seals on both sides to retain grease while limiting friction-generating drag. C3 internal clearance provides extra radial play, making it well suited for applications where the shaft or housing runs at elevated temperatures or where press-fit mounting reduces internal clearance. Licensed HVAC technicians, pump service technicians, and millwrights are the typical installers.\u003c\/p\u003e\u003cp\u003eThis bearing sees common use in belt-drive and direct-drive HVAC blower motors, circulator pumps, fan shaft assemblies, and light industrial equipment where moderate radial loads and moderate-to-high speeds are expected. The low-torque light contact seal design reduces parasitic drag compared to heavy-contact or rubberized full-contact seals, which is an advantage in variable-speed motor applications and energy-sensitive installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e60 mm bore x 130 mm outer diameter x 31 mm width — standard 6312 series envelope\u003c\/li\u003e\n\u003cli\u003eDouble-sided light contact seals (2RD) retain lubrication while minimizing frictional drag\u003c\/li\u003e\n\u003cli\u003eC3 internal clearance for use in applications with elevated operating temperatures or interference-fit mounting\u003c\/li\u003e\n\u003cli\u003eLow-torque design reduces parasitic load on motors and drive systems\u003c\/li\u003e\n\u003cli\u003ePre-greased and sealed — no field lubrication required at installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement bearing for motors, pumps, blowers, and rotating equipment requiring a standard 6312-series deep groove ball bearing with C3 clearance and double light contact seals.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician. De-energize and lock out the equipment before removing the old bearing. Use a proper bearing press or hydraulic puller to seat or remove the bearing — never strike the outer or inner race directly with a hammer, as this damages the raceways and rolling elements. Consult equipment manufacturer torque specifications for housing fasteners and verify shaft and housing fit tolerances before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 60 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 130 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 31 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Type\u003c\/strong\u003e: Light contact seal, double-sided (2RD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Clearance\u003c\/strong\u003e: C3\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: KOYO6312-2RDC3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KOYO","offers":[{"title":"Default Title","offer_id":51467393761586,"sku":"KOYO6312-2RDC3","price":105.76,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945047.png?v=1783903374","url":"https:\/\/voomisupply.com\/products\/koyo-koyo6312-2rdc3-deep-groove-ball-bearing-c3","provider":"Voomi Supply","version":"1.0","type":"link"}
