Description: Rolled Ball-Screws generates low friction and smooth running for a linear feeding system compared to traditional screws. These are manufactured using the most advanced technology in the ball-screw rolling process by carefully controlling the procedure, material selection, rolling process, heat treating, machining, and assembly. 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. If the ends of the spindles are unmachined, the geometric tolerance is not applied.
