Trapezoidal thread spindles double-start, RH thread Material: Low-carbon steel 1.0401 (C15) or stainless steel 1.4301. Version: Steel, rolled, bright. Stainless steel, rolled, bright. Sample order: nlm 24001-120611X1000 Note: Rolled trapezoidal thread spindles with high precision. ISO trapezoidal thread based on DIN 103. The feed movement is twice as high with double-start spindles as it is with single-start trapezoidal thread spindles. There is no self-locking due to the high pitch. Description of a double-start thread drive based on Tr 12x6 P3. Tr = trapezoidal thread. 12 = OD. 6 = Thread...

24003 Trapezoidal thread nuts, round single-start, RH or LH thread Material: Steel C35Pb. Stainless steel 1.4305. Gunmetal Rg7. Plastic PA6.6 (mit MoS2). Version: Bright. Plastic nuts: for low-noise motion drives. Good dryrunning properties. Order No. LH thread stainless steel Gunmetal nuts: for motion drives with low and medium speed. By insufficient lubrication, gunmetal trapezoidal thread nuts have good dry-running properties on steel spindles. Order No. LH thread steel Steel and stainless steel nuts: for adjustments during manual operation and as locking nuts. Not advised for use with...

24010 Splined shafts similar to DIN ISO 14 0 D1-0,08 Material: C45 steel or 1.4301 stainless steel. Version: Cold-drawn, bright. Sample order: nlm 24010-11141X1000 Note: Spline shafts based on DIN ISO 14 with straight parallel flanks. A spline shaft with spline hub is used to transmit high torques while enabling simultaneous axial movement. The spline shafts are cold-drawn. Cold drawing does not interrupt the grain flow of the base material, ensuring spline shafts of very high strength. Tolerances: Straightness 0.8 mm/m. Torsion max. 0.5 mm/m. On request: Other lengths. Order No. stainless...

Splined hubs round similar to DIN ISO 14 D2 Material: Steel C45. Stainless steel 1.4305. Gunmetal Rg 7. Version: Bright. Note: Spline hubs based on DIN ISO 14 with straight parallel flanks. A spline shaft with spline hub is used to transmit high torques while enabling simultaneous axial movement. Order No. stainless steel

24011-01 Splined hubs with flange similar to DIN ISO 14 L Material: Steel C45. Stainless steel 1.4305. Gunmetal Rg 7. Version: Bright. Sample order: nlm 24011-01-11141 Note: Spline hubs based on DIN ISO 14 with straight parallel flanks. A spline shaft with spline hub is used to transmit high torques while enabling simultaneous axial movement. Order No. stainless steel

Technical information for ball screw linear actuators Efficiency and self-locking: The low rolling friction of ball screw linear actuators give them a mechanical efficiency of up to 95%. Operating duration can be 100%. Due to low rolling friction ball screw linear actuators are not self-locking. A brake mechanism must be installed where selflocking is required (reduction gear or motor brake). This is a must by vertical installations. Operating temperature: Ball screw linear actuators can be used with normal loads within a temperature range of -20 to +80 °C. Temporarily up to +110 °C. A...
