Electric positioner 4765

linear2-axisworm gear

Use: positioning adjustable on 2 axes with handwheel on worm screw for frequent adjustments. State of supply 2 nickel-plated steel columns (electrolytic nickel-plating), phosphated steel trapeze screws and lead nuts, brass sliding bearings, 1 aluminium carriage, galvanised steel nuts and bolts. Characteristics: Tr20 worm screw, pitch 4 (1 handwheel turn = 4 linear mm). Positioning accuracy: ±0.3 mm/300mm*. Operation: STEP-BY-STEP (NO continuous operation). Max. 120 rpm; max time: 1 (min; on/off ratio=1/60 Millimetre scale marking p. . 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.).
