Deep - groove roller bearings have a higher load capacity than equal-sized deep-groove ball bearings because the rollers perceive the available radial load along the line, and the balls-at the point of contact. In some cases, it is allowed to use roller radial bearings of a higher accuracy class with short cylindrical rollers in nodes with relatively high rotation speeds. The design of such bearings depends on the presence (or absence) of thrust sides on the outer or inner ring. Deep-groove roller bearings may have a slight axial displacement of the rings during operation, thereby compensating for the thermal elongation of the shaft. Deep-groove roller bearings with short cylindrical rollers require more precise alignment of the seats during installation, otherwise there is an edge pressure of the rolling bodies on the raceways of the rings. This leads to a sharp decrease in the service life of the bearings. d 750 D 1090 B 775 C (kn) 19758 Co (kn) 63006 Rs min(mm) 20х20° rs min(mm) 7,5 weight(kg) 2568
