Datasheet EKM-VA

Product catalog summary

Overview: The document provides technical specifications for the EKM-VA series elastomer couplings designed for drive technology applications. These couplings feature a stainless steel design, are easy to assemble with a clamping hub, and offer a backlash-free, plug-in, compact, and vibration-damping solution.

Technical Specifications:

Temperature Range: -30°C to +90°C or -20°C to +120°C
Material: Hubs made of stainless steel 1.4305, elastomer spider made of Polyurethane, screws conforming to ISO 4762, stainless steel A4-80
Dimensions: Length dimensions according to DIN ISO 2768 cH

Performance Data:

Nominal Torque: Ranges from 6 Nm to 650 Nm
Hardness: 98 Sh-A or 72 Sh-D
Moment of Inertia: Varies from 0.08 to 14 x 10^-3 kgm²
Torsional Stiffness: Ranges from 0.09 to 12 Nm/arcmin
Max Shaft Misalignment: Axial ± 0.5 to 1 mm, Lateral 0.1 to 0.15 mm
Lateral Spring Rate: 600 to 9600 N/mm
Max Speed: 8000 to 29000 Upm
Mass: Approximately 0.2 kg to 7 kg

Dimensional Data:

Various sizes with specific dimensions for Øa, c, e, g, h, L, f-TS, ØD1/2 min, ØD1/2 max, and ØD1/2 prebored
Torque specifications for screws ranging from M4 to M14 with corresponding Nm values

Conclusion: The EKM-VA series elastomer couplings are suitable for a wide range of applications due to their robust design, flexibility in temperature range, and high-performance characteristics. They are ideal for environments requiring precise torque transmission and vibration damping.
