JWB (Ball screw type)
Model number JWB~
The JWB (Ball screw type) is a screw jack that uses rolling friction to enable energy-saving operation.
- -The main components are precision Ball screw and high-precision worm gears.
- ・High efficiency:
Ball screw provides high efficiency and produces a large thrust with a small drive source. - ・Higher speeds:
Compared to Trapezoidal Screw types, the increased efficiency of the screw allows for smoother operation at higher speeds. - ・Long life:
It uses a highly reliable Ball screw, ensuring a long life. - *It does not have a self-locking mechanism, so a brake is required.

JWH (High lead ball screw type)
Model number JWH~
The JWH (High lead ball screw type) is a screw jack that uses a high lead Ball screw, allowing it to achieve even higher speeds (up to 4 times faster) at the same input rotation speed as the JWB type.
- -The main components are a high-lead Ball screw and a high-precision worm gear.
- ・High speed:
By using a highly reliable high-lead ball Ball screw, the screw shaft speed can be increased to a maximum of 7.5 m/min. - ・Low noise:
For the same speed as JWB (Ball screw type), a deceleration unit is used in the drive source to reduce the input rotation speed.
This allows for a quieter jack. - *It does not have a self-locking mechanism, so a brake is required.

JWM (Trapezoidal Screw type)
Model number JWM~
JWM (Trapezoidal Screw type) is a standard type screw jack suitable for low speed and low frequency use.
- -The main components are a concentric Trapezoidal Screw and a high-precision worm gear.
- Economical:
Its simple and compact structure makes it economical. - ・Low speed/low frequency:
Taking advantage of the sliding contact Trapezoidal Screw characteristics, it is ideal for low speed, low frequency applications. - ・Load retention:
Trapezoidal Screw are calculated to have self-locking properties, and can be expected to retain load.
*Self-locking may become ineffective due to vibration, impact, etc. - ・Stainless steel screw specifications available:
For the two models, JWM025 and JWM050, the screw shaft is standardized with austenitic stainless steel. - Left-hand thread specifications available:
The input rotation direction is the same, but the screw moves in the opposite direction to the right-hand screw specification.
