MR115 Full Ceramic Bearing, ABEC9, 5 x 11 x 4 mm, 2PCS Description: precision full ceramic bearings designed for fishing reels that require a compact MR115 size. These bearings are made entirely from ceramic materials for low weight, heat tolerance, and resistance to corrosion. Supplied as a pair, each bearing is grease and engineered for smooth, lowfriction rotation. Key specifications: Model: MR115 full ceramic bearing Bore diameter: 5 mm Outer diameter: 11 mm Width: 4 mm Precision: ABEC9 Clearance: C0 standard Ball material: Ceramic Bearing material: Ceramic Condition: Grease, running Quantity: 2 PCS Application: Fishing reel bearing Primary benefits: precision ABEC9 tolerance for consistent, lowfriction rotation that supports smoother spool performance. Full ceramic construction reduces weight and centrifugal force on spinning elements, supporting higher rotational speeds. heat resistance for reliable operation under heavy use. Nonmagnetic and electrically insulating properties expand compatibility with specialized reel designs. Grease design resists contamination and is easier to flush or relubricate for saltwater or freshwater maintenance. Suitable for environments where steel bearings may corrode or degrade. Compatibility and fit: Direct replacement for bearings specified as MR115 or 5 x 11 x 4 mm. Use when a compact, precision ceramic bearing is required for reel spools, drive systems, or small rotating assemblies. Practical use scenarios: worn spool bearings in a spinning reel to restore smoother retrieves and more consistent spool spin. Upgrade bearings in a baitcasting reel where reduced weight and speed stability improve casting performance. Install in saltwater or mixedenvironment reels where ceramic materials reduce corrosion risk and simplify maintenance. Notes: These bearings are supplied grease for users who prefer to install with their choice of lubricant or to run dry as appropriate for the application. Precision ABEC9 and C0 clearance reflect the bearing manufacturing tolerance and standard internal clearance.
