SKAK 4048 aluminium cross slotted coupling
All-metal cross slotted coupling made of aluminium, ideal for high torques. It provides backlash-free, angle-synchronised transmission of rotary movements, is torsionally rigid and vibration-damping, as well as compensating for misalignment.
Please also compare our lighter versions made of plastic SKMS 1520 or glass fibre reinforced plastic SKPS 1520 and SKPS 2224.
