JWB ball screw elevator

JWB series (ordinary ball screw elevator) has high efficiency; By using rolling friction, the overall efficiency of the machine is improved, and only a small driving source is needed to generate a large amount of driving force. High speed: Compared with trapezoidal screws, the lifting speed has been greatly improved, making it easy to adjust and operate.

JWB series (ordinary ball screw elevator)
Suitable for high-speed and high-frequency operating environments.
The JWB series (ordinary ball screw elevator) is suitable for high-speed, high-frequency, and high-performance devices, mainly composed of precision ball screw pairs and high-precision worm gear pairs.
High efficiency: By using rolling friction, the overall efficiency of the machine is improved, and only a small driving source is needed to generate a very large driving force.
High speed: Compared with ordinary trapezoidal screws, the operating speed has been greatly improved, making it easy to adjust and operate.
Long service life: Using high-quality ball screw pairs, its working life is more than three times longer than ordinary trapezoidal screw pairs.
