High-efficiency ball screws These ball screws are designed for applications requiring high efficiency of the transmission. They are used especially in machine tools and other equipment which meet the requirements for low energy consumption, as well as where high efficiency is required in order to eliminate heat sources or when an optimal ball screw drive is needed. The high efficiency is achieved by an accurate thread profile ground section, by precise geometry of the groove and alternatively by the use of ceramic balls in the recirculation system. These ball screws are produced in the precision classes IT1 to IT5. For this type of ball screws the following nut types are available: All types of nuts, non-preloaded nuts with backlash up to 0.05 mmCharacteristics: Application of ceramic balls, special gothic thread profile Precise positioning ground ball screws Standard geometric and working accuracy according to DIN ISO 3408 Reduced Tp values (usually by 15 to 20% against the standard)Technical parameters: Diameters from 12 to 63 mm Recommended pitch up to 10 mm Precision classes from IT1 to IT5 Do×n = 80.000, efficiency 96–98% (according to thread pitch and lubricant) Minimum strength of the shaft material Rm= 650MPa, functional surfaces of the shaft and nut hardened to 58–60HRC Working temperature -20 to +60°C A lubricant with reduced noise is recommended for a smooth runApplications: Energy saving machine tools Laboratory and measuring equipment Aerospace industry These ball screws have no separate technical parameter table and they can be supplied with different nut units (A, AP, A+A, AP+A, APR). Example of designation: K63x10 – 4/AP HE/2 (ball screw with diameter 63 mm and pitch 10 mm, 4 working threads, single non-preloaded nut with flange, high efficiency design, flange type 2) High-efficiency ball screws : www.ks-kurim.cz/en/ball-screws/high-efficiency-ball-screws/

Linear actuators The linear actuator provides drive controlled linear motion within the range of the working stroke, thus replacing hydraulic cylinders. It converts the rotary motion into linear actuation by the use of a ball screw with minimum transition efficiency 95%, stroke range 150–600 mm upon axial load from 12.5 to 25kN. The actuation speed can be regulated or set by a suitable selection of the pitch of the used ball screw in relation to the used electric motor.

Ball screws for low speed and precise positioning These ball screws are used in applications in which high accuracy and low speed of positioning are required. They are suitable especially for precise machine tools. The shaft thread is generally ground. These ball screws are only available with double preloaded nuts AP+A, or A+A. The ball screws are offered in IT1 precision class and for their maximum thread length the following formula should be kept: Lz = 20×Do. The load capacities of these ball screws are reduced to 70% of the load capacity of standard ball screws due to the reduction of the number of balls in the nuts. The main advantages of these ball screws are their high accuracy and smooth run. Furthermore their high flexibility allows the production of ball screws exactly according to the customer’s needs. For this type of ball screws the following nut types are available: Double preloaded nuts Characteristics: Precise ground positioning screws with IT1 precision class Standard geometric and working accuracy according to DIN ISO 3408 Reduced tolerance of Tp values (usually by 10 to 15% compared to the standard) Delivered with customized preloadTechnical parameters: Diameters from 20 to 80 mm Recommended pitches 5 and 10 mm, thread lengths to 20×Do Precision class IT1 Do×n = 80,000, efficiency 94–97% (according to thread pitch and lubricant) Minimum strength of the shaft material Rm= 650MPa, functional surfaces of the shaft and nut hardened to 58-60HRC Working temperature -20 to +60°C (according to lubricant type) Lubricants with increased resistance to unstable high pressure are recommendedApplications: Precise machine tools – grinding machines, EDM and laser machines These ball screws do not have a separate technical parameter table and are delivered as customized solutions with respect to the limitations mentioned above. Example of designation: K40x5 – 4+4/AP+A PP/2 (ball screw with diameter 40 mm, with pitch 5 mm, 4 working threads, preloaded double nut AP+A, precise positioning design, flange type 2) Ball screws for low speed and precise positioning : www.ks-kurim.cz/en/ball-screws/ball-screws-for-low-speed-and-precise-positioning/
