The bush of the series CB is an attachment suitable for the production of single and double acting hydraulic cylinders. Made of Fe510C and welded on the endplug and/or on the chromed plated rod, it allows a fastening with pins (it does not enable a radial movement but only a rotating movement on the same axis). This attachment is used in our standard cylinders HM2,HFR/HFR2S. This item is advisable for all the sectors.
