SW 686 ZZ Miniature Deep Groove Ball Bearing (6x13x5mm) | High Speed, Shielded
The SW 686 ZZ is a precision miniature deep groove ball bearing engineered for high-speed, low-torque applications where space is severely restricted. Featuring a 6mm bore, 13mm outer diameter, and 5mm width, this bearing uses a robust deep groove raceway geometry optimized for managing both radial and moderate axial loads. The 'ZZ' designation confirms the use of non-contact metal shields on both sides, providing excellent protection against contaminants while retaining high-quality, long-life lithium grease, ensuring minimized friction and sustained operational integrity across demanding cycles. Constructed from hardened 52100 bearing steel, the 686 ZZ maintains exceptional dimensional stability and hardness for extended service life, meeting stringent ABEC precision standards typical of SW industrial products.
Designed for integration into critical systems such as micro-motors, precision instrumentation, robotic actuators, and high-performance RC equipment, the SW 686 ZZ offers a superior balance of performance and reliability. Its compact design and high limiting speed capabilities make it an ideal choice for OEMs seeking dependable components for delicate machinery. By utilizing SW’s proprietary surface finishing technology, the bearing ensures smooth running characteristics and reduced noise levels, providing an optimal solution for applications requiring both high RPM and low maintenance intervals. Rely on the SW 686 ZZ for consistent, precision movement in your most challenging micro-mechanical assemblies.
