Datasheet SKB-EK

Product catalog summary

Overview: The document provides technical specifications and details for drive technology components, specifically focusing on elastomer attachments with lateral clamping hubs on both sides. These components are designed to be plug-in, flexible, backlash-free, and oscillation dampening.

Specifications:

Dimensions are in accordance with DIN ISO 2768 cH standards.
Elastomer spider shore hardness can be customized upon request.
Materials used include heat-treated steel for safety parts, high-tensile aluminum for clamping hubs, and polyurethane for elastomer spiders.
Temperature range for operation is from -30°C to +90°C.

Technical Data:

Various sizes are available, each with specific setting ranges, moments of inertia, mass, torsional stiffness, and maximum shaft misalignment.
Tightening torque specifications for screws are provided, with variations depending on the size and configuration.
Disengagement torque (TKA) is specified for different sizes, indicating the torque at which the coupling will disengage.

Material Details:

Safety parts are made from heat-treated steel.
Clamping hubs are constructed from high-tensile aluminum, with size 2000 using tempered steel.
Elastomer spiders are made from polyurethane with a hardness of 98 Shore A.
Screws conform to ISO 4762 / 12.9 standards.

Size and Configuration:

Detailed dimensions and configurations are provided for various sizes, including SKB-EK and SKB-KP series.
Each size has specific dimensions for components such as Øa, Øb, Øc, and others, along with corresponding tolerances.

Recommendations:

For larger hub bore diameters, reduced tightening torque is recommended.
Consult the series SKB-ES for coupling sides with conical hubs.
