Datasheet SKW-EK

Product catalog summary

Overview: The document provides technical specifications and details for the SKW-EK series safety coupling designed for direct drives. It highlights the key features, materials, and technical data relevant to the product.

Key Features:

Elastomer attachment for direct drives with easy keyway connection.
Radial clamping hub for elastomer coupling, offering plug-in, backlash-free, flexible, robust, and oscillation-dampening characteristics.

Technical Specifications:

Dimensions are in accordance with DIN ISO 2768 cH standards.
Ordering example provided: SKW - EK 60 - D1 = Ø 32 G7 - D2 = Ø 24 H7 with PFN 8P9 x 3.3 - T KA = 55 Nm.
Material composition includes heat-treated steel for the safety part and high tensile aluminum for the clamping hub, with tempered steel for size 2000.
Elastomer spider made of polyurethane with a hardness of 98 Shore-A, suitable for temperatures ranging from -30°C to +90°C.

Technical Data Table:

Includes size, setting range, disengagement torque, moment of inertia, mass, torsional stiffness, maximum shaft displacement, and tightening torque of screws.
Sizes range from 6 to 2000, with corresponding torque and dimensional specifications.

Additional Notes:

Other shore-hardnesses of the elastomer spider are available upon request.
Optional axial fixing of the safety part can be achieved with an additional snap.
