SKPS 1520 and SKPS 2224 cross slotted couplings made of glass fibre reinforced plastic

The SKPS 1520 and 2224 cross slotted couplings are the somewhat more stable versions of our cross slotted couplings. These compensating couplings have a glass fibre-reinforced polyamide centre section.

They have similar advantages to the SKMS (weight, price), but have higher performance values due to the glass fibre reinforcement. They are available in 15 or 22 mm diameter and 20 or 24 mm length.

Compare our SKMS 1520 variant and our stronger aluminium variant SKAK 4048.
