linearsingle-axis positioningworm gear

Use: positioning adjustable on one axis with worm screw for frequent adjustments. State of supply 1 column in nickel-plated steel (electrolytic nickel-plating), trapeze screw and lead nut in burnished steel, ball bearings in steel, 1 carriage in RAL9006 grey aluminium, galvanised steel nuts and bolts. Characteristics: Tr20 worm screw, pitch 4 (1 handwheel turn = 4 linear mm). Position accuracy: ±0.3 mm/300mm* travel (pitch tolerance ±0.004 mm) Carriage play: 0.5°. Play is eliminated when fitted in pairs of two positioners, or by combining it with a linear guide for precision and load bearing.Operation: STEP-BY-STEP (NO continuous operation). Max. 120 rpm; max time: 1 (min; on/off ratio=1/10 (max 10%). * the ACCURACY indicated is theoretical. Accuracy levels depend on the actual conditions of use and are affected by the accuracies of the kinematic chain - consisting of the handwheel/crank handle/revolution counter kit or any connection joints - and by the performance of the position control system (encoder, etc.).
