Prism Pairs with Clamping Strap M318.264 — Metav IndustryLine, special steel, DIN 876/0, 0.008 mm accuracy

The Prism Pairs with Clamping Strap M318.264 deliver secure, repeatable support for cylindrical components in inspection, assembly and light machining setups, with an emphasis on stable positioning and straightforward clamping.

• Special steel construction, DIN 876/0
• 90° centre cut for precise alignment
• Suitable for shafts Ø5–45 mm with clamping strap

Stable support for fragile and heavy shafts

The prism set is built from special steel, providing a firm contact surface that minimises elastic deformation during clamping and measurement. With a compact footprint of 125 x 90 x 70 mm and a substantial mass of 10.3 kg, the unit resists movement under load and keeps the workpiece centred. The included clamping strap secures the component without excessive force, reducing slippage and enabling consistent results across repeated cycles — a practical advantage for production sampling and bench inspection.

Measured repeatability for quality control

Designed to meet DIN 876/0 tolerances, the prisms deliver an accuracy of 0.008 mm, which supports tight alignment and repeatable fixturing in quality assurance processes. This level of accuracy makes the set suitable for precision inspection tasks where concentricity and axial runout matter. The nominal accuracy value indicates how closely measurements or alignments can be reproduced when the same setup is recreated, helping to reduce scrap and rework in downstream operations.

Faster setup and reliable alignment on the shop floor

The 90° centre cut simplifies the initial placement of round parts and, together with the clamping strap, shortens setup time compared with bespoke fixtures. The profile and angle of the bearing surfaces guide shafts into a defined datum, so adjustments are reduced and throughput increases. For workshops handling batches of shafts or cylindrical assemblies, this translates into measurable gains in productivity while maintaining the geometric conditions required for accurate machining or inspection.

Versatile compatibility with common inspection tooling

Prepared for shafts ranging from Ø5–45 mm, the prism pair integrates well with existing measurement benches and manual inspection rigs. Its form factor and datum geometry make it easy to combine with dial indicators, bore gauges and other metrology equipment used for concentricity checks, runout measurement and centreline verification. The robust construction also makes the unit suitable for light clamping in assembly or balancing operations where a reproducible support is essential.

Durable design and low-maintenance operation

Finished contact faces on the prisms ensure smooth seating and repeatable contact points; the special steel composition balances wear resistance with machinability for occasional reconditioning if required. Routine upkeep is limited to keeping the surfaces clean and free of abrasive debris. The combination of a solid build and simple mechanical clamping yields long service life and predictable performance in demanding workshop environments.

FAQ

What shaft diameters can be supported with these prisms?
The prism pair supports shafts in the Ø5–45 mm range; the clamping strap secures components within that diameter span for inspection and light machining.

How precise is the alignment provided by the prism set?
Alignment accuracy is specified as 0.008 mm and the design conforms to DIN 876/0, offering repeatable positioning suitable for standard quality control tasks.

Are the prisms suitable for use on a measurement bench with dial indicators?
Yes — the prism geometry and stable base are intended for integration with dial indicators, bore gauges and similar metrology instruments for runout and concentricity checks.

What maintenance is required to keep the prisms accurate?
Regular cleaning of contact surfaces and protection from abrasive contaminants are normally sufficient; the special steel construction provides wear resistance for long service life.

Is the clamping strap included and how does it affect repeatability?
The clamping strap is included and, when used correctly, ensures consistent axial restraint without excessive deformation, improving repeatability in serial checks.
