Series-S high duty screw jacks are a range of metric cubic screw jacks designed to have a higher duty cycle and mounting flexibility over conventional worm gear screw jacks. Typically the duty cycle can be extended by 50%. The higher duty rating has been achieved by improving the design of the jacks worm gearbox. The screw jacks are available in capacities from 25kN to 200kN in both translating and rotating screw configurations.

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.
- 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

Screw jack is one of the most used and cheap mechanism used for a wide variety of uses as lifting or moving any kind of load, even unbalanced ones. It can be used individually or in groups so to operate in perfect synchronisation. BP RIDUTTORI screw jacks are irreversible and don't need additional locking system. They are fully produced in our factory, and they guarantee high quality standard. The case is made of spheroidal cast iron or aluminium and the worm gears is made of special UNI 7816 18NCD5 iron, grounded on both the thread and shaft. It's possible to produce every NON STANDARD version to meet our customer request.
