ROSA - Model GR Type - Cross Rollers/Balls Rails - Brochure

GR type linear system bearings could utilize either cross roller or ball as rolling elements.The two will differ substantially in load ratings.The ratio is approximately 10 to 1 in favor of rollers, depending upon the dimention under consideration. Balls are more advantageous in case of presence of impurities and/or misalignment as it happens when the structure, to which rails are anchored, is not sturdy enough to support them and rails are not therefore placed in their correct position. Such systems offer good load rating with respect to the cross section, lenght and relative stroke.They utilize different cages and end pieces depending upon the application.
