Product Description

JW series screw jack overview: 1.JWM (Trapezoid screw) JWM (trapezoidal screw) is suitable for low speed and low frequency. Main components: Precision trapezoid screw pair and high precision worm-gears pair. &#***0; Economical: Compact design ,easy operation, convenient maintenance. &#***0; Low speed, low frequency:Be suitable for heavy load, low speed, low service frequency. &#***0; Self-lock: Trapezoid screw has self-lock function, it can hold up load without braking device when screw stops traveling. Note:Braking device equipped for self-lock will be of malfunction accidentally when large jolt & impact load occur. 2. JWB (General ball screw) JWB (General ball screw) is suitable for high speed, high frequency and excellent performance.Main components: Precision ball screw pair and high precision worm-gears pair. &#***0; High efficiency: Rolling friction improve efficiency greatly, only a little drive power can generate great thrust force. &#***0; High speed:Rolling friction speed up travel of screw easily. &#***0; Lifetime longer: High precision ball screw can make JWB's lifetime longer by 3 times comparing with JWM. Note ;Braking devices or motor with braking devices are necessary when choosing JWB &#****8;&#***4; Direct-connected-motor&#****0; Ability of load: 1.*****0kW Power: 0.****1kW
