Material: Steel 1.0401 (C15). Version: Rolled, bright. Note: Trapezoidal threads are transmission threads with relatively high friction. Standard thread forms are self-locking. This has the advantage that it generally does not need to be secured in the rest position. DIN 103 (apart from pitch Tr 10x3) Tolerance class 7e Pitch precision 0.3/300 mm On request: Lengths max. 3000 mm.

Trapezoidal thread round nuts Material: Gunmetal Rg7 Version: Bright. Sample order: nlm 24003-1003132 Note: For low and medium speed linear actuators. By inadequate lubrication gunmetal trapezoidal thread nuts have good dry-running properties on steel spindles. Tolerance class 7H. Trapezoidal thread flange nuts Material: Gunmetal Rg7 Version: Bright. Sample order: nlm 24005-160411 Note: For low and medium speed linear actuators. By inadequate lubrication gunmetal trapezoidal thread nuts have good dry-running properties on steel spindles.

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 self-locking is required (reduction gear or motor brake). This is a must by vertical installations. Note: Ball screw linear actuators consist of a ball screw spindle, a ball screw nut in which the balls are integrated and a ball re-circulator. They are used...
