Cylindrical test mandrel M318.912 — Ø40×400 mm, runout 0.005 mm (Metav IndustryLine)

A cylindrical test mandrel engineered for precise runout verification of shafts and bore interfaces in inspection and workshop environments

• Cylindrical mandrel Ø40×400 mm
• Runout accuracy 0.005 mm
• Hardened gauge steel construction
• Both ends centred for secure seating

Repeatable runout verification for quality control

The mandrel delivers repeatable runout control thanks to its specified runout accuracy of 0.005 mm, which classifies it as a high‑precision inspection tool for shaft and bore concentricity checks. Tight runout tolerances reduce the need for rework and speed up acceptance tests; this means shorter inspection cycles and clearer pass/fail decisions at first measurement. The dimensional stability of the component ensures measurement results remain consistent across multiple setups, which is essential for process control and traceability in production environments.

Durable design that withstands workshop use

Manufactured from hardened gauge steel, the mandrel combines surface hardness with dimensional resilience for prolonged service life under regular use. The Ø40×400 mm format balances accessibility and stiffness: long enough to check medium‑length components while remaining rigid in typical inspection fixtures. The mandrel’s both ends centred feature simplifies mounting and prevents wobble during rotation, so set‑up time is reduced and handling becomes more predictable even on busy benches.

Integration into inspection workflows and practical handling

This inspection shaft is intended for direct use in runout and concentricity tests on rotating mounts, chucks or support centres. The mass and geometry (approx. 8 kg) provide stable inertia during low‑speed rotations, improving measurement fidelity. Use with standard inspection runners, dial indicators or optical systems for comparative checks; the mandrel’s clear specification streamlines documentation and reporting. For tailored advice on fixturing or compatibility with specific gauges and test benches, the Metav technical team can provide application‑oriented recommendations.

FAQ

What runout performance can be expected from this mandrel?
The cylindrical test mandrel M318.912 achieves a specified runout accuracy of 0.005 mm, making it suitable for high‑precision concentricity and runout checks in routine inspection tasks.

Is the mandrel suitable for use in rotating tests and chucks?
Yes. The Ø40×400 mm geometry and centred ends allow safe mounting in chucks or between centres; the mass and stiffness support stable low‑speed rotation for comparative measurements.

What is the mandrel made from and how does that affect longevity?
Constructed from hardened gauge steel, the M318.912 offers enhanced wear resistance and dimensional stability, prolonging service life under normal inspection use.

Can this mandrel be used for both shaft and bore verification?
The design is intended for runout and concentricity checks on shafts and interfacing bores; its centred ends facilitate accurate seating for both internal and external alignment tests.
