Model: 683 (3 x 7 x 3 mm) Full Ceramic Bearing — Pack of 3 Key benefits Smooth, consistent rotation: precision fullceramic construction reduces friction for smoother spool movement and more efficient energy transfer. Corrosionresistant and durable: ceramic bearings resist rust and chemical attack, making them ideal for humid or saltwater environments where metal bearings fail. Longlasting performance: fullceramic bearings wear more slowly than steel equivalents, reducing the need for frequent replacement and helping maintain peak reel performance. Quiet operation: ceramic components cut vibration and noise for a quieter, more pleasant user experience. What this bearing is and why you need it The 683 fullceramic bearing is a compact, precision bearing with inner diameter 3 mm, outer diameter 7 mm, and width 3 mm. It's sized for small reels and other compact rotating assemblies where space and smooth operation matter. If your reel suffers from roughness, sticking, corrosion, or noisy operation, upgrading to fullceramic bearings can restore smooth spool rotation and extend service life. Supplied as a set of 3 pieces so you can multiple bearings at once or keep spares for future maintenance. Key attributes Model: 683 Dimensions: 3 x 7 x 3 mm (ID x OD x Width) Construction: Full ceramic (ceramic races and balls) Quantity: 3 pieces per package Function: Lowfriction rotational support for small spindles and shafts Performance: Improved smoothness, reduced wear, corrosion resistance, lower noise Compatibility and typical applications Designed for small fishing reels, baitcasting or spinning reel components that accept a 683size bearing. Suitable for compact rotating mechanisms in angling equipment, precision instruments, micromotors, and other small devices requiring a 3 x 7 x 3 mm bearing. Useful for , upgrade, or maintenance tasks where corrosion resistance and longterm smooth operation are desired. Use cases 1) Fishing reel upgrade: corroded or worn stock bearings on a small spinning or baitcasting reel to restore smooth spool action, reduce line friction, and improve casting responsiveness. 2) Precision equipment : Install in small instruments or micromotors that demand low friction, minimal maintenance, and resistance to environmental corrosion. 3) Spare parts for maintenance: Keep the threepiece set as service spares to quickly address bearing failures and minimize downtime for small devices. Practical notes Confirm your reel or device accepts a 3 x 7 x 3 mm (683) bearing before installation. Fullceramic bearings are wearresistant and corrosionresistant; they typically require less frequent lubrication than steel bearings but follow your device manufacturer's maintenance recommendations. Handle with care during installation to avoid chipping ceramic components; pressfit with appropriate tools and avoid uneven force. What you get Three (3) units of 683 fullceramic bearings, each 3 x 7 x 3 mm, ready for immediate installation or as spares for future maintenance.
