JW series screw jack overview:
Ability of load:1.96-980kN
Power:0.25-21kW
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.
* Economical: Compact design ,easy operation, convenient maintenance.
* Low speed, low frequency:Be suitable for heavy load, low speed, low service frequency.
* 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.
* High efficiency: Rolling friction improve efficiency greatly, only a little drive power can generate great thrust force.
* High speed:Rolling friction speed up travel of screw easily.
* 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
