JW series screw jack overview:
• Flexible installation, due to it's ability to move upwards, downwards, auxiliary propelled and height could be easily adjusted
• Drive ability: Screw Jack Reducer can be driven by electrical motors or other power drivers or even manually
•Stable transmission, Screw Jack Reducer is designed and uses aluminium bronze for that worm wheel which offers better strength, durability, less noise, higher reliability, and free lock
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
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 Screw jack.
