1pcs SMR117ZZ Ceramic Bearing 7x11x3 mm (SMR117C ZZ, MR117ZZ) Hybrid Ceramic Bearing Product highlights Exact size: 7 x 11 x 3 mm for direct fit in applications specifying SMR117 series dimensions. Hybrid ceramic design: ceramic rolling elements paired with hardened steel races to reduce friction and improve running stability. Doubleshielded (ZZ): metal shields on both sides help keep out dust and contaminants while allowing smooth rotation. Single unit: 1 piece per , suitable for replacement or projects. Cross references: identified as SMR117ZZ, SMR117C ZZ, MR117ZZ, L1170ZZ. Also shown alongside SMR83CZZ 3x8x3 mm as a related small bearing size reference. Key benefits Smoother operation and higher speed capability due to lowfriction ceramic rolling elements. Improved durability compared to fullsteel bearings in many smallscale rotary applications, reducing the need for frequent replacements. Compact 7 x 11 x 3 mm profile fits tight assemblies and minimizes added axial space. Double shielding reduces ingress of grit and extends service life in dustprone environments. Function and compatibility Function: supports radial loads while enabling lowfriction rotational movement in small mechanisms. Compatibility: designed for devices and assemblies that accept SMR117 series bearings or equivalent 7 x 11 x 3 mm bearings. Use model references SMR117ZZ, SMR117C ZZ, MR117ZZ, and L1170ZZ to confirm fit. Typical applications Fishing reels and line counters: smooth spool rotation and consistent drag performance. Small electric motors and brushless gimbals: stable speed rotation and reduced vibration. Precision hobby and RC components: steering linkages, wheel hubs, and rotating joints where compact, lowfriction bearings are required. Installation and care notes Handle with care during pressfit installation to avoid damaging shields or races. Light lubrication compatible with hybrid ceramic bearings can extend life in many uses; follow equipment manufacturer guidance for lubrication and tolerances.
