Description

Material
Poliuretano.
Versión
Estrella de acoplamiento azul 80 Shore A.
Estrella de acoplamiento amarilla 92 Shore A.
Estrella de acoplamiento roja 98 Shore A.
Indicación
The spiders are the compensating elements in elastomer dog couplings. As the main component of a coupling, they determine its properties.

The spiders are available in various hardness grades. As the hardness of the coupling spider increases, the torque and stiffness transmitted increases, and as the hardness decreases, the displacement capacity and cushioning increases.

Pre-tensioning of the spiders in the coupling hubs make this variant play-free.
Temperature range
Blue Shore 80A: -50 °C to +80 °C. Briefly -60 °C to +120 °C.
Yellow Shore 92A: -30 °C to +90 °C. Briefly -50 °C to +120 °C.
Red Shore 98A: -30 °C to +90 °C. Briefly -40 °C to +120 °C.
