Features:Electric putter, also known as push rod motor, electric cylinder and linear actuator.The electric putter is an electric drive that converts the motor's rotational motion into a straight reciprocating motion of the push rod.Can be used in a variety of simple or complex process as the implementation of mechanical use, in order to achieve long-range control, centralized control or automatic control.Main use: electric bed, electric sofa, electric stand lift rod, industrial electric lift system, camera frame, video machine, wedding system.How it works:After the motor is slowed by the gear, drive a pair of screw nuts. The motor rotation into a linear motion, the use of motor reversal to complete the putter action. Such as through a variety of lever, rocker or connecting rod and other institutions to complete the rotation, shakeand other complex movements.Low noise design,noise level is 50dB.Specifications:Size: Approx. 20.5 x 4.0 x 7.5cm/8.1 x 3 x 1.6inchWeight: 1070 gMaximum thrust: 750NStandard Stroke: S = 100mmMinimum distance (the distance between the front and rear of the two holes) :L = S(stroke)+ 105mm putter between two holes = 2XS(travel)+ 105mmNo load speed: 10mm/s Speed and thrust relationship: 5mm / s (kg) -50s (50kg)Standard protection level: IP54Noise level: 50 dBPackage Included:1 x Electric Linear Actuator Motor2 x Bracket2 x Bolt2 x Cotter Pin for the Linear Actuators.
