2 pieces S683 2RS stainless steel precision bearings — 3 x 7 x 3 mm, ABEC7, rubber sealed (2RS). Designed as direct replacements for 683 / S683 / SMR683 / SMR683 2RS reels bearings and similar miniature rotary applications. Why you need these bearings Smooth, lowfriction rotation: ABEC7 precision reduces wobble and resistance for smoother spool and shaft movement. Protection from contaminants: Dual rubber seals (2RS) keep out dirt, dust, and moisture so bearings last longer and perform reliably. Corrosion resistance: Stainless steel construction resists rust and wear in wet or humid environments common to reels and outdoor gear. Exact smallsize fit: 3 mm inner diameter x 7 mm outer diameter x 3 mm width fits equipment designed for 683/S683/SMR683 series bearings. Key features and specifications Quantity: 2 pieces Model / compatible numbers: S683 2RS, 683, S683, SMR683, SMR683 2RS Size: 3 x 7 x 3 mm (ID x OD x width) Precision class: ABEC7 Material: Stainless steel (rings and balls) Seal type: 2RS — rubber sealed on both sides Application focus: reels bearings and other miniature rotary assemblies What makes these bearings effective precision ABEC7 tolerance improves balance and reduces vibration in small, speed spindles. Dual rubber seals reduce the need for frequent maintenance and protect lubricant from contamination. Stainless steel construction delivers long service life even in damp or corrosive conditions. Practical use cases Fishing reels and spinning reels — worn bearings to restore smooth retrieve and casting performance. Small electric motors, micro gearboxes, and precision mechanisms — ideal for compact shafts where reliable, lowfriction rotation is required. RC equipment, camera gimbals, and other miniature rotating assemblies that require sealed, corrosionresistant bearings. Installation and care Dropin replacement for 683/S683/SMR683size housings and shafts; verify shaft fit (3 mm ID) before installation. Bearings are presealed; additional lubrication is generally not required but can be applied if the application specifies a particular grease. Avoid forcing bearings onto shafts; use proper pressing tools to prevent damage to seals and raceways. Included 2 x S683 2RS stainless steel rubbersealed bearings (3x7x3 mm, ABEC7) Use these bearings when you need compact, precision, sealed components that restore or improve smooth rotation in reels and other small rotating devices.
