Bevel Gear Screw Jacks

Bevel gear screw jacks use grinding-grade spiral bevel gear for high-speed and high-duty circle application. Bevel gear screw jacks are more efficient and faster than worm-driven screw jacks, so it’s the best choice for many applications. As a professional manufacturer, we can supply standard and customized types to meet your application requirements.

Common Bevel Gear Jacks Layouts

Bevel gear jack can be made in three shafts, so it eliminates the need for miter gearboxes and makes it an ideal choice for multi-jack systems. Several common layouts are shown here.

For multiple jack layouts, motor power depends on the horsepower per jack, the number of jacks, the miter gearbox’s efficiency, and layout efficiency. Layout efficiency : Two bevel jacks = 95%,  Three bevel jacks = 90%,  Four bevel jacks = 85%, Six to eight bevel jacks = 80%

• A wide range of reliable driven units, connecting shafts, gearboxes, motors, etc., to meet your exact function requirement.
• Whether a complete system or a single unit, whether driven by hand or motor, you can get a complete solution from us.
