Brief: Standard screw jacks (trapezoidal screw): This safe design includes a self-locking feature. This series includes a self-locking feature through the use of a trapezoidal screw making it possible to hold the screw shaft even if there is an unintended power cut off. Grease lubrication is used for the worm reduction section.
Brief: A wide selection of types and models, high availability of ratios and Screw pitches, strokes on request assure a considerable range of selection and application. Screw Jacks are manufactured in the standard configuration Upright/Inverted Translating Screw with male, female Screw end or top plate, Upright/Inverted Rotating Screw with flanged nut. We do not have standard Work Screw length and each Screw Jack is manufactured following specific requirements.

Brief: Acme Screw Jacks having high gear ratios and standard design are generally self-locking and will hold loads without backdriving in the absence of vibrations. Trapezoidal Work Screw thread. Positive mechanical actuation. Precise positioning. Uniform speed. Available with the Anti-backlash device.
Brief: How Screw Jacks Work? Main components of screw jacks are trapezoidal lifting screw, worm screw, worm gear and gear housing. Worm screw is rotated manually or by motor. Worm gear is rotated by worm screw. The lifting screw moves through the rotating worm gear. The linear motion speed of lifting screw depends on thread size and rotation ratio of worm gears.
Brief: 35 Ton Ball Screw Jack Main components include a high-lead ball screw and a high-precision worm gear. Which requires less input rpm at the drive and reducer units to run at the same speed as the standard ball screw type jack, enabling quiet jack operations. Self-locking is not provided, so a brake unit is required.
Brief: 25 Ton Ball Screw Jack Using high precision ball screw. Integral ball nut and worm wheel. Grease lubricant ensure high speed operation. Ideal bearing structure, excellent performance. It consists of worm gear and ball screw and high precision and efficiency, suitable for frequent use. Worm Wheel rotate by turning input shaft (worm shaft) that transmit propulsive force to screw jack. Lubrication of worm and screw is both grease. Ball screw has no self-locking function, brake system is required. High precision, large screw shaft Use ball screw.
Brief: 20 Ton Ball Screw Jacks Configurations: Upright Translating Ball Screw Jack, Inverted Translating Ball Screw Jack, Upright Rotating Ball Screw Jack, Inverted Rotating Ball Screw Jack, Double Clevis Ball Screw Jack, Upright Anti-rotation Ball Screw Jack, and Inverted Anti-rotation Ball Screw Jack. It is used only when the load to be moved (actuated) may rotate, i.e. the screw is unguided and does not prevent rotation. The anti-rotation device consists of a square steel tube which guides the movement of a square aluminium bronze guide block fitted to the end of the ball screw. The guide block also acts as a stop nut.
Brief: 10 Ton Ball Screw Jacks are highly efficient and require a brake or other external locking device to hold position, and only require up to two-thirds less input torque to move the load than similarly rated 10 Ton Machine Screw Jacks. Available in 8:1, 12:1 and 24:1 gear ratios. Available in Translating, Keyed for Non Rotation, Traveling Nut designs.
Brief: 1 Ton Ball Screw Jack is born from the experience in 1 Ton Machine Screw Jacks. They have the greater efficiency and rolling action, the ball screw jacks can operate at higher speeds or increased duty cycle when compared with the machine screw jacks. The addition of a high efficiency ball screw and nut reduces the required input torque. Required approximately two-thirds less input torque to move the load than similarly rated machine screw jacks.
Brief: 5 Ton Ball Screw Jack has no self-locking function, this jack has high efficiency (about 3 times that of trapezoidal screw jack) and saves energy because of the rolling motion between the nut and screw. Like the trapezoidal thread-type screw jack, this machine permits the measurement of the lifting screw lead by the amount of rotation of the input shaft and also multi-point synchronous operation by connecting machines of the same type.
Brief: Right angle bevel gear drives are ideal for applications with limited space and where the driven equipment needs to be close to each other. This design allows for changes in axis rotation along with smooth transfer of power with minimal backlash. Gearboxes serve different functions based on the ratio and are typically used in conveyors, rotary axis drives, and drivetrains. Right Angle Gearboxes with a ratio greater than 1:1 can also be used as a speed reducer. Our right angle gearbox lineup includes shaft to shaft, shaft to bore, bore to bore, 2 shaft, 3 shaft, high ratio, and low profile models. All our Bevel T right angle gearboxes are built with a single output shaft extended out both sides of the box, so both ends rotate simultaneously in the same direction.
Brief: 2.5 Ton Ball Screw Jacks are common where higher speeds and duty cycles are needed. Most screw jacks use trapezoidal screws Tr, because they are simple, robust and inexpensive. The proportion of screw jacks that use ball screws is however constantly increasing. The reasons for this are primarily their pitch accuracy, their high efficiency (less power consumption and less heat generation) and the higher pitches available, which permit higher stroke speeds.
Brief: Bevel T Shape Gearbox, which is used widely in various industrial machines as a high precision and high strength structure's power dividing equipment, provides a robust function and performance to meet the customer's requirement.

Brief: 300 kN Cubic Ball Screw Jack actuators may be used individually, in tandem or in multiple arrangements, connected by shafting, couplings and miter gear boxes. Special models are also available. Single end worm shafts with left or right hand extensions are furnished at no extra charge.
Brief: 100 kN Cubic Ball Screw Jack Drives for high number of cycles and high duty cycles, but without self-locking quality. High life-time with ball-screw drives with dynamic load capacities, which are above standard drives. This results in multiple life-time. Three-phase AC motors and servomotors are available as standard drives. Mechanical or electrical synchronisation of several actuators is possible.
Brief: 50 kN Cubic Ball Screw Jack Actuators are available in two types: translating screw and rotating screw. In the translating screw type, the ball nut is fixed to a rotating gear within the housing, and the lifting screw moves up and down through the nut. In the rotating screw type, the screw is fixed to the rotating gear, and the ball nut travels up and down the screw.
Brief: Compact precision screw jacks are specifically designed to provide highly precise lifting, lowering and pivoting of loads. These units feature a cubic housing (machined on all sides) made out of high quality grey cast iron, ensuring excellent durability and long service without any need for maintenance (under normal operating conditions). The motor and screw jack assemblies were designed for installation in any position, while the unique form of the worm gearing helps reduce inter-gear specific pressures, and further improves durability. The worm unit is made out of hardened and ground alloy steel of top quality.
Brief: Worm gear compact machine screw jacks lift and precisely position loads. Upright or inverted jacks operate at full capacity in tension or compression. single lead jacks are self-locking. double lead jacks offer increased travel speed and require a brake or external locking device to hold position. Features: Alloy steel input shafts. Aluminum bronze wormgears. Tapered or ball thrust bearings provide rugged reliability. Double input shafts standard. Protective boots available. Anti-backlash devices available. Customized mechanical jacks can be made to your specifications.
