These yokes, swivel heads and flexo couplings can be used in almost all standardised and non-standardised cylinders and represent only a small selection of the accessories for pneumatic cylinders available from us (e.g. acc. to ISO 6432, ISO 15552, ISO 21287 or UNITOP). Fastening material for a specific type of cylinder or a specific standard can be found directly with the respective cylinders. Tip: Flexo couplings can significantly increase the service life of the cylinders for alignment inaccuracies between cylinders and load.
