Datasheet KM

Product catalog summary

Overview: The document provides technical specifications for metal bellows couplings, specifically the KM series, highlighting features such as 6-corrugation bellows, easy installation with lateral EASY-clamping hubs, and a low-cost standard series.

Specifications:

Dimensions: Length dimensions conform to DIN ISO 2768 cH.
Material: Hubs are made of high-tensile strength aluminum, with stainless steel bellows.
Temperature Range: Operates between -40°C and +200°C.
Screws: Comply with ISO 4762 / 12.9 standards.

Technical Data:

Torque Range: From 0.4 Nm to 1300 Nm, with specific tightening torque requirements for larger hub bore diameters.
Moment of Inertia and Torsional Stiffness: Varies by size, with detailed values provided for each model.
Max Shaft Misalignment: Axial misalignment of ±1 mm and lateral misalignment of 0.3 mm.
Spring Rates: Axial and lateral spring rates are specified for each model.
Maximum Speed (nmax): Ranges from 7000 upm to 20000 upm depending on the model.

Order Example: KM 170 - D1 = 30 G7, D2 = 35 H6, with variable length options for larger clamping hub sizes.

Additional Notes:

For higher torques and steel hub versions, refer to series 'KG'.
Reduced tightening torque is necessary for larger hub bore diameters.

Dimensions and Mass: Detailed dimensions and mass for each coupling size are provided, including minimum and maximum bore diameters.
