SJ Series Screw Jack Worm Gear Reducer Hand Crank/Electric Screw Lift Mechanism

BMSeries Worm Gear Screw JacksBall bearingSpiral Elevator)A mechanically integrated motion execution unit that ingeniously combines motors, reduction systems, screw drives, etc. It can be used individually or in a combination of multiple units, similar to interlocking building blocks, connected by right-angle turners, couplings, and connecting rods, allowing for precise control of the lifting, reciprocating, and flipping movements of the mechanism. This unit can replace traditional hydraulic and pneumatic transmission in various applications, offering engineers ample design space for developing products in the digital age, primarily focusing on worm gear and screw lifting mechanisms. It is widely used in industries such as solar energy, metallurgy, food processing, water conservancy, and more.BMThe unique square groove housing of the ball screw lifting jack enhances its heat dissipation capabilities and extends the service life of the lubricant. The choice of cast iron material for the housing significantly improves the strength and performance of the housing, as well as its ability to withstand high temperatures./Wide application under low temperatures. Square tail cover design to prevent the screw from self-rotating. Advanced processing equipment and assembly technology ensure high product quality. The innovative design concept creates products with strong impact resistance, high strength, low noise, long lifespan, and compact size.

Ball Screw Worm Gear Lift Calculation

Ball screw lifting jackBMThe lifespan of the series products is primarily determined by the lifespan of the ball screw and other components such as worm gears and worm.;We primarily verify the lifespan of ball screw, while worm gears may experience wear.,But typically, the lifespan is longer than that of ball screws.

Expected life of ball screwL10Certainly90%The operational distance a ball screw can achieve or exceed before experiencing fatigue failure in metallic materials. Unit: million millimeters. Expected lifespan of the ball screwL10Not a guarantee of quality,Expected lifespan is to be achieved with proper maintenance, absence of contaminants, and correct lubrication.

If the expected lifespan of the ball screw needs to be higher than90%Multiply the expected lifespan by the following coefficient.

95%: L10x62%  96%:L10x53%  97%:L10x44%  98%:L10x33%    99%:L10x21%

If you need assistance in selecting a screw jack that meets your requirements, please provide the following parameters::

1Lifting Weight, Unit:KG;

2.Lifting Speed:Every minute or every second, the lead screw or nut moves a certain length;3Ball screw motion form:Screw thread movement, or nut movement;

4.One or several elevator installations;

5Does it directly connect to the drive motor?
