Carbon Steel High Rigidity Single/Double Disc Coupling, Keyway Type

Brand :

MISUMI

Caution

Product Description

This is an economy item, The price is cheaper than the MISUMI standard product.

Product Overview

A high-rigidity, flexible coupling with a diaphragm fastening mechanism.
[Features]
• Standardized 10 models and 45 sizes with shaft diameters from φ12 (12mm) to φ50 (50mm).
• High torsional stiffness due to the ingenuity of the diaphragm fastening mechanism.
• Allows for deflection angles and end clearances.
• Low moment of inertia.
[Applications]
• Machine tools, precision platforms, etc.

Dimensions

Precautions

Static torsional stiffness, moment of inertia, and weight are values at the maximum shaft diameter.

Eccentricity, deflection angle, and axial amplitude are individual allowable values. If multiple deviations occur simultaneously, the allowable values for each deviation are reduced to half of their original values.

For selection criteria and calibration adjustments, please refer to

pages 788 and 789.

Eccentricity is not permitted for single-diaphragm types.
