Single bucket excavators are one of the most frequent types of construction machines, as shown in this work (CM). Due to a variety of advantages over a mechanical drive, the vast majority of them use a hydraulic drive. The hydraulic drive, on the other hand, has a significantly poorer reliability. Hydraulic cylinders are the most significant factor limiting its dependability. One of the shortcomings of the existing design of the most popular double-acting reciprocating hydraulic cylinder on road-building machines with a one-sided rod is that it has a deflection before applying an operational longitudinal compressive force. This type of deflection is defined as the total amount of deflection caused by misalignment of the primary bearing parts (stem and sleeve).
