Prism Pair M318.291 — Cast inspection prism, 75×40×30 mm, 90° accuracy 0.064 mm

The Prism Pair M318.291 is a cast, hardened steel support prism designed for precise positioning and inspection of cylindrical parts in measurement and machining setups

• Hardened special steel construction
• 90° precision: 0.064 mm tolerance
• Compact 75×40×30 mm dimensions
• Suitable for shafts Ø5–40 mm

Stable 90° support for cylindrical inspection

The prism pair provides a precise 90° seating for round parts, enabling angular reference and secure support during visual inspection, measurement or light machining operations. With an angular tolerance of 0.064 mm, the set reduces alignment error when checking runout or perpendicularity, which directly improves the reliability of comparative measurements. This performance is particularly useful in quality-control routines where a consistent datum is required for successive components.

Durable construction for repeatable setups

Manufactured in hardened special steel and produced as a cast pair, the units combine rigidity with wear resistance for long-term stability. Compliance with DIN 876/2 signals an established workmanship standard that supports reproducible seating geometry over many cycles. The robust build minimises micro-movements under light clamping forces, so fixtures and test jigs retain their reference points and reduce rework caused by inconsistent supports.

Compact footprint, easy integration in the workshop

At 75×40×30 mm, this prism pair occupies minimal bench space while still offering secure support for shafts and rollers. Compatibility with precision measuring tools is direct: the prisms are suitable for shafts Ø5–40 mm and work well with a precision caliper or gauge when checking diameters, concentricity and runout. The small size allows quick repositioning in test benches or inspection fixtures and supports streamlined measurement flows in mixed-production environments.
