A brief review of existing and newly developed methods for calculating the friction moment of radial bearings of rocking units is given using the most common domestic articulated steering units of liquid-propellant rocket engines as an example. An analysis of the kinematic diagram of the steering drive is carried out, the leading element of which is the shaft of the launch vehicle steering machine. Analytical dependencies of the time-varying force coming to the actuator of the steering unit are obtained, which were subsequently compared with a similar experimental characteristic recorded during a full-scale fire test. An analytical and graphical dependence of the load on the actuator as a time function at specified angular velocities of the steering unit shift is given, the procedure for converting this force into a radial load on the bearing is shown. The field of application of the obtained refined data in studying the torque characteristics of low-speed radial bearings of steering units is determined.
