of which is determined by the load character. Special care should be taken in the construction of docking mechanism guides built according to the combined scheme (Figure 3.7) since the rod is loaded and displaced during shock absorption and coupling. During shock absorption one must insure displacement of the rod when affected by substantial lateral forces; thus friction in the guides should be minimal. The rear support of the guides consists of four bail or roller bearings in a cruciform configuration. These bearings move in the grooves of the tail part of Figure 3.7.

This support absorbs a radial load in an arbitrary direction and torque. The support maintains work capacity during partial or even complete jamming or breakdown of individual bearings.
