Extension for three‑point internal measuring system (IMS) — 152.4 mm length, D 23.5 mm (Metav IndustryLine)

The Extension for three‑point internal measuring system (IMS) adds controlled reach to internal measuring setups, providing a 152.4 mm long adapter that keeps measuring geometry stable across mid‑range bores

• 152.4 mm extension length for extended reach
• Compatible with M21 thread connections
• Fits internal ranges 50–100 mm

Reliable access into confined bores while preserving alignment

The extension supplies a consistent, repeatable means of reaching deeper or recessed internal diameters without modifying the base measuring head. With a defined outer diameter of 23.5 mm and a fixed length of 152.4 mm, the adapter limits lateral play at the interface and helps maintain the original contact geometry of the internal measuring device. This stability reduces the need for repeated fixture adjustments and supports faster inspection cycles when several depths must be checked in sequence. The accessory integrates into the measuring chain as a dedicated spacer rather than a makeshift extension, improving process repeatability.

Seamless integration with three‑point systems and common workshop ranges

Delivered with an M21 mounting thread, the component interfaces with three‑point internal measuring systems that accept this connection standard. It is specified for internal diameter applications spanning the typical workshop bands 50–63 mm, 62–75 mm, 75–88 mm and 87–100 mm, allowing the same measuring head to cover multiple bore sizes through rapid changeover. The adapter’s mass (1.3 kg) contributes to a balanced assembly in many bench and fixture arrangements, reducing the influence of unwanted vibrations during manual gauging or light automated cycles.

Designed for dependable use in inspection and production environments

As a purpose‑built accessory from Metav IndustryLine, the extension focuses on functionality and integration rather than on additional user calibration or complex interfaces. The simple threaded connection preserves the familiar handling and maintenance routines of standard measuring systems, while the clearly defined geometry supports traceable setups in quality control workflows. When used as part of a controlled measuring process, the adapter helps to shorten setup time between diameters and keeps inspection throughput predictable under routine workshop conditions.

FAQ

Is this extension compatible with all three‑point internal measuring systems?
Compatibility depends on the mounting interface; the extension uses an M21 thread and is designed for three‑point internal measuring systems that accept this connection and the listed bore ranges.

Which internal diameters can be measured when this extension is fitted?
When used with compatible three‑point systems, the adapter supports the internal diameter bands 50–63 mm, 62–75 mm, 75–88 mm and 87–100 mm as specified for the product.

What mounting and handling considerations apply?
The extension attaches via an M21 thread; attention to correct torque and alignment is advised to preserve contact geometry and repeatability during inspection routines.

Will the extension affect measuring accuracy?
The adapter is intended to preserve the original measuring geometry; correct mounting and stable fixturing limit additional sources of error, but final accuracy depends on the complete measuring chain and calibration practice.
