Po\u010det polovi\u010dn\u00ed zuby pro typ RB<\/h3>\n

RB double pitch sprockets are listed with half-tooth counts (6\u00bd, 7\u00bd, 8\u00bd) because only alternate teeth engage the large rollers of the RB chain \u2014 the remaining teeth pass through the plain-pin spaces between rollers. A “6\u00bd tooth” RB sprocket engages 6 rollers and 7 plain pins per revolution. This gives smooth motion with fewer engagement impacts than a same-size SB sprocket where all teeth engage rollers.<\/p>\n<\/div>\n
