Datasheet ESM-A

Product catalog summary

Overview: The document provides technical specifications for the ESM-A series elastomer couplings used in drive technology. These couplings are characterized by features such as a conical hub, clamping ring, plug-in design, backlash-free operation, rotational symmetry, and suitability for high speeds.

Specifications:

Material Composition: The elastomer spider is made of polyurethane, with size 2000 using tempered steel. The screws conform to ISO 4762 / 12.9 standards. The conical hub is made of high-tensile aluminum, and the clamping ring is heat-treated steel, burnished.
Dimensions: Length dimensions follow DIN ISO 2768 cH standards.

Technical Data:

Nominal Torque and Hardness: Ranges from 10 Nm (98Sh-A) to 2000 Nm (98Sh-A).
Moment of Inertia and Torsional Stiffness: Varies with size, e.g., 0.015 x 10^-3 kgm² and 0.09 Nm/arcmin for size 10, up to 75 x 10^-3 kgm² and 21 Nm/arcmin for size 2000.
Max Shaft Misalignment: Axial ±1 mm, lateral 0.1 to 0.15 mm depending on size.
Lateral Spring Rate: Ranges from 600 N/mm to 9000 N/mm.
Tightening Torque of Screws: From 2 Nm to 100 Nm.
Maximum Speed (nmax): From 35000 upm for size 10 to 7000 upm for size 2000.

Dimensional Data:

Dimensions and mass vary by size, with specific measurements provided for each size, including diameter, length, and pre-bored dimensions.

Applications: The ESM-A series is suitable for applications requiring high precision and reliability in rotational movements, such as in mechanical and drive systems.
