Transport ball screws Transport ball screws are used in applications where high accuracy of positioning is not required, such as for example in transporting and lifting devices, wood processing machines, etc. The screw shaft is produced by rolling or whirling and the shaft ends are machined according to the request of the customer. They are equipped as a standard with an APE type of nut, which is a single non-preloaded nut with flange. These ball screws are produced in the T5 and T7 precision classes. Their main advantage is a lower price. Characteristics: Productive and quick production of the screw Non-preloaded nut with backlash 0.015–0.05 mm (depending on the ball screw size) Standard geometric and working accuracy according to DIN ISO 3408 for transport ball screwsTechnical parameters: Diameters from 12 to 63 mm – rolled, from 32 to 100 mm – whirled Recommended pitch up to 10 mm – rolled and up to 30 mm – whirled Precision class T5, T7 Do×n = 80,000, efficiency 93–95 % (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°CApplications: Transporting mechanisms Wood processing machines Substitution of racks Long actuation assemblies Example of designation: K63x10 – 4/APE TS (ball screws with diameter 63 mm and pitch 10 mm, 4 working threads of the APE single nut with flange, transport design, the standard type 3 of the flange is not pointed out).

Telescopic ball screws It is a complex assembly of several ball screws screwed in one. Each nut has the additional function of a bearing for the fixation of the next shaft from the assembly of ball screws. The unique construction with mutual bonds of the individual components secures simultaneous turning and actuation of all ball screws at once. In such a way multiplication of the stroke per one revolution of the drive is achieved. The telescopic ball screw replaces hydraulic cylinders, with the advantage of easy control and positioning. The telescopic ball screw takes advantage of the basic properties of the ball screws, in which the highly efficient rolling of balls in the thread profiles of the screw and the nut is used for the transition of the rotary motion into linear. Telescopic ball screws are appreciated for their compact length in comparison with the achieved total actuation. This property can be used at places where it is necessary to solve actuation without the possibility to apply through and long lifting mechanisms, such as for example in the case of various handling platforms. The telescopic ball screw can be used in machine tools with unconventional kinematic structure (hexapods). Telescopic ball screws : www.ks-kurim.cz/en/additional-assortment/telescopic-ball-screws/

Guide rods Guide rods are structural components suitable for accurate and highly efficient linear guidance of the moving parts of various mechanisms. They are produced from hardened, ground and straightened circular cross section shafts and can be mounted in clamping bars, sockets and other clamping elements. The guide rods are supplied with a relevant rolling guide according to the required operation load and type of the guide rod. Guide rods that have been properly designed, calculated and applied do not require any special supervision or maintenance. However, they should be protected against dust, water and aggressive environments. In combination with ball screws and suitable drives they constitute basic construction motion units used in various machines and equipment. Guide rods are usually produced from steel grades CF53 or 42CrMo4 and afterwards are induction heat treated to 58 – 60HRC. Assembly Before the start of operation the conservation oil layer should be removed and the guide rods should be cleaned properly. The guide rods are usually implemented with linear bushings. They should be accurately aligned in parallel with the direction of motion of the linear bearings with precision 0.02 mm/1,000 mm. In the event of any warranty repair the guide rods should be sent to the producer as a complete rolling guide assembly. Lubrication For the lubrication of the guide rods, suitable lubricants include those used for ball bearings as well as relevant plastic lubricants which are applied once on basis of the recommendation of manufacturers of rolling guides.
