Screw jack lifting machines (ball screw lifting machines) are a cleverly integrated electromechanical motion execution unit that combines motors, reduction systems, and screw drives. They can be used individually or in combination with multiple units, like building blocks, connected by right-angle drives, couplings, and connecting rods. They can accurately control the lifting, reciprocating, and flipping movements of mechanisms according to a set program. This makes them a suitable replacement for traditional hydraulic and pneumatic drives in various applications. As a motion unit primarily consisting of screw jack lifting machines, it offers engineers a broad design space for developing products in the digital age. They are widely used in industries such as solar energy, metallurgy, food, and water conservancy.

The SJB ball screw jack features a square groove housing for enhanced heat dissipation and extended lubricant life. The choice of nodular cast iron for the housing material significantly boosts the housing's strength and performance, and allows for widespread use in both high and low-temperature environments. The square tail housing design prevents the screw from rotating freely. The precision machining equipment and assembly process ensure high production volumes, while the design philosophy creates products with strong impact resistance, high strength, low noise, long service life, and compact size.
