The analysis of results of researches of influence of geometrical characteristics of shpindelny knot pintles on the accuracy of boring of radical support under bearings of cranked and distributive shaft in cases of internal combustion engines is made. The researches executed on the basis of calculation of rigidity of a spindle, its bearing support, optimum interbasic distance of shpindelny knot pintles, allowed to establish interrelation of numerical values of geometrical characteristics boring the pintles, containing a spindle-borshtangu on the taken-out support and precision characteristics of machining of coordinate coaxial openings of bearing support in preparations of cases. The established dependences expand idea of opportunities of application of shpindelny knots on portable support and confirm possibility of expansion of a positive know-how in achievement of high precision of processing by boring of coaxial bearing support of cases in the range of diameters from 50H7 to 230H6 mm.
