Rolled Ballscrew

Description: PRECISION ROLLED BALLSCREWS Rolled Ballscrews feature a rolled screw spindle instead of one that is ground. Rolled ball-screws generate low friction and runs smoothly for a linear feeding system compared to traditional screws. It is cost effective. These can be classified into two grades: precision rolled grade (PR), and high precision rolled grade (HR). In general, both grades use the same preload method as precision ground ball-screws, except that there are some differences in the lead error definition and geometry tolerances. Each type of rolled ball-screw can be ordered according to the nut dimension of precision ground ball-screws.
