Cylindrical gauge mandrel M318.914 — Ø50 × 750 mm, 0.005 mm runout accuracy (Metav IndustryLine)

Cylindrical gauge mandrel M318.914 is a precision inspection mandrel designed for runout and concentricity checks in metrology and production control, suited to workshop and laboratory environments

• Hardened gauge steel construction
• Runout accuracy 0.005 mm
• Both ends centred for secure mounting
• Ø50 × 750 mm mandrel length

Minimise rework with traceable runout control

The mandrel delivers a runout accuracy of 0.005 mm, enabling consistent verification of concentricity and spindle alignment. By using a rigid, hardened gauge steel body, the device maintains geometric integrity during repeated handling and offers a stable reference for comparative measurements. This level of precision reduces scrap rates and shortens throughput times by catching deviations early in the production chain.

Built for repeatable mounting and simple inspection routines

With both ends centred, the mandrel facilitates secure mounting in chucks, centres or test fixtures, improving reproducibility between measurements. The generous Ø50 × 750 mm length covers larger assemblies while the solid construction keeps deflection minimal. For inspection planners this translates into fewer setup steps and more reliable batch control, so quality checks become a predictable part of the workflow rather than a bottleneck.

Robust design that supports shop‑floor and lab environments

Manufactured from hardened gauge steel, the mandrel resists wear and preserves datum surfaces over prolonged use, supporting a long service life and stable measurement references. The substantial mass (approx. 23.5 kg) contributes to vibration damping during on‑machine checks, while the centred ends simplify integration with existing jigs and measuring stands. As a precision gauge, it supports both quick go/no‑go verifications and more detailed runout assessments.

FAQ

What applications is this mandrel suited for?
The cylindrical gauge mandrel M318.914 is intended for runout and concentricity checks of shafts, spindles, bores and assemblies where a precise cylindrical reference of Ø50 × 750 mm is required.

How should the mandrel be mounted for measurement?
Mounting is simplified by the fact that both ends are centred; the M318.914 may be supported between centres, in a chuck or in a dedicated fixture to achieve repeatable readings.

Is the material suitable for workshop use?
Yes. The mandrel is made from hardened gauge steel, providing durability and stable reference surfaces under normal shop‑floor and laboratory conditions.

Can the M318.914 be used for on‑machine runout checks?
The mandrel’s mass and rigidity make it appropriate for on‑machine or bench inspection of runout, provided the chosen support and mounting method secures the mandrel without introducing additional runout.
