Trapezoidal thread spindlessingle-start, RH or LH thread Material: Steel 1.0401 (C15) or stainless steel 1.4301 (whirled spindles stainless steel 1.4305). Version: Steel rolled, bright. Stainless steel up to Tr 40x7 rolled, above this whirled, bright. Sample order: nlm 24000-100311X1000 Note: Rolled, high precision trapezoidal thread spindles. ISO trapezoidal thread based on DIN 103. The trapezoidal thread spindle is a transmission thread with relatively high friction. Standard thread forms are self-locking. This has the advantage that they generally do not need to be secured in the rest...

Trapezoidal thread spindlesdouble-start, right-hand 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 =...

Splined shaftssimilar to DIN ISO 14 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. Order No. Profile No. of B...

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 selflocking. A brake mechanism must be installed where self-locking 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...
