SJB worm gear screw jack electric hand crank spiral ball screw lifter

The worm gear screw jack (ball screw jack) is a mechatronic motion execution unit that ingeniously combines an electric motor, a reduction system, and screw transmission. It can be used individually or in multiple combinations, like building blocks, connected via right-angle steering devices, couplings, connecting rods, and other linkage components, and can accurately control the lifting, reciprocating, flipping, and other movements of the mechanism according to specific programs. As a result, it can replace traditional hydraulic and pneumatic transmissions in various scenarios. This motion unit, primarily based on the worm gear screw jack, provides engineers in the digital era with broad design space for product development. It is widely used in solar energy, metallurgy, food, water conservancy, and many other industries.

The ball screw jack features a unique square groove housing that enhances the heat dissipation capacity of the shell and extends the service life of the lubricating grease. The selection of ductile iron as the shell material significantly improves the strength and performance of the housing, as well as its applicability in high/low-temperature environments. The square tail cover design prevents the screw from rotating. Advanced processing equipment and assembly processes ensure high product quality, while innovative design concepts create superior products with strong impact resistance, high strength, low noise, long service life, and compact size.
