ALS/AL
The ALS Starflex jaw coupling can be offered with clamping hub and/or with keyway as well as three different spiders, which differ in hardness and coupling backlash.
The red (97 Shore A) and yellow (90 Shore A) spiders are completely backlash-free due to their shape, whereas the blue (97 Shore A) spider is suitable for applications with backlash. The torques of the applications can reach up to 1050 Nm for a short time.
As an alternative to the ALS Starflex, we can recommend the less expensive AL Sprflex. It has a simpler design and is available pre-drilled ex works or with finished bore within a very short time.
