The 3/16 Inch Constant Section Bearings are engineered for applications where radial space and weight are extremely limited yet high rotational accuracy is required. This series maintains a uniform three-sixteenths inch cross-section regardless of the bore diameter allowing for streamlined designs in precision instruments and aerospace components. Manufactured from high-quality chrome steel these bearings provide excellent stiffness and low friction torque making them ideal for compact optical systems and miniature robotic joints where imperial measurements are the standard requirement.
