Mitutoyo 465 Series Extension Rod for Cylinder Gauge

The Mitutoyo 8.7 mm Pipe Diameter Extension Rod for Cylinder Gauge 6127931 is a supplementary component used to extend the reach and measuring Rangee of the gauge when inspecting deep or hard-to-reach cylindrical bores or holes. It is a crucial accessory in dimensional metrology, quality control, and precision machining processes, where accurate measurement of internal diameters is essential. The extension rod is designed as a slender, cylindrical shaft made from high-quality materials such as hardened steel to ensure stability and durability. It typically features a threaded end that securely attaches to the existing measuring head of the cylinder gauge. The opposite end incorporates a measuring contact, usually a carbide or ruby-tipped probe, which makes contact with the inner surface of the bore to capture the dimensional data. Using the extension rod involves first affixing it to the main measuring head of the cylinder gauge. The extension length can vary depending on the specific model and application requirements, allowing for the accommodation of varying depths of bores or holes. Once properly attached, the cylinder gauge, equipped with the extension rod, is carefully inserted into the bore, reaching the desired depth for measurement. Extension rods for cylinder gauges are available in various lengths and diameters, providing versatility and adaptability to diverse measurement scenarios. Additionally, some models feature built-in mechanisms for adjusting the measuring contact's position to cater to different bore sizes and ensure optimal measurement accuracy.
