Rail de guidage linéaire AGORA Technique

Material: Carriage die-cast zinc. Mounting plate aluminium. Bearing material iglidur® J. Version: Carriage chromed. Mounting plate anodized. Note: DryLin® W carriages are maintenance-free and corrosion resistant. Lacking the need of lubrication makes the system highly dirt resistant. Low friction coefficient in dry running and very quiet. Due to the flat and wide design, high torques are possible. Speeds up to 15 m/s. Applicable temperature -40 °C to +90 °C. Accessory: Double guide rails 21240.

Threadless ball screws The threadless ball screw is designed mainly for handling mechanisms of manipulators and transporting devices, which require effective transition of the rotary motion to linear without the preference of high rigidity and load capacity, but with the requirement for simplicity, easy maintenance and easy production. Screw thread is produced only in the nut and the transition of the load is provided only through the balls in the nut and the smooth cylindrical surface of the shaft. The principle is based on the elastic deformation of the surface of the hardened and ground shaft caused during the rolling of the preloaded balls guided in the inner screw thread of the nut. In this application it is possible to use the slippage of the nut on the shaft after exceeding certain axial force as a safety element. The nut continues in its motion in the original direction after the decrease of the load, or the current increase causes drive disconnection.

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/
