The guide ring meets the base with a flat surface rather than a curved one. This design choice prevents sliding and shaking at the base junction and delivers a more stable connection. Key benefits - Flat base contact: the flat surface where the ring meets the base ensures flush seating and reduces misalignment. - Reduces movement: by eliminating curvature at the contact point, sliding and wobble are minimized during engagement. - Improves stability: a steadier connection enhances overall reliability and consistency in operation. Function and compatibility - Function: provides a stable, repeatable connection between the guide ring and the base. - Compatibility: designed for assemblies that require a flat contact interface at the base to achieve reliable mating. Performance - Stability under use: less movement at the base improves alignment accuracy and reduces wear from shifting. - Repeatable mating: the flat contact supports consistent performance across repeated connections and disconnections. Use scenarios - Scenario 1: mounting a precision sensor or small module to a base where accurate alignment is essential for correct readings. - Scenario 2: attaching a fixture or jig in a vibration-prone workflow to minimize drift and maintain stable positioning during operation. - Scenario 3: assembling base components in a lab instrument or machine that benefits from a fixed, repeatable base connection for reliable performance.
