Ball screw jack cast iron

3XX-ST
A ball screw jack cast iron from BJ-Gear A/S is a device designed to convert rotary motion into precise linear motion. It is used in various applications requiring high efficiency, speed, and precision. The ball screw jack is particularly suitable for continuous operation due to its high efficiency, which limits heat accumulation in the spindle and nut. This makes it ideal for industries such as healthcare, food processing, packaging, aerospace and defense, and more. It can be customized to meet specific requirements and is capable of handling loads at high linear speeds, up to 25,000 mm/min.

Description

Ball screw jack cast iron

Worm gear screw jacks with ball screw spindle 

A worm gear screw jack with ball screw spindle provides advantages over the trapezoidal spindle in relation to efficiency, speed, precision and running time. By using a standard worm gear screw jack with ball screw spindle, you can achieve a linear speed of up to 25,000 mm/min. Since the ball screw has a very high efficiency, it will limit the accumulation of heat in the spindle and nut. That makes the ball screw suitable for continuous operation.

Maintenance of the gearboxes: 

The gearboxes are lifetime lubricated and require no special maintenance. However, for gearboxes with heavy load, the oil should be changed approximately every five years. Gearboxes working in very warm environments may require oil change once a year. NOTE: All data stated are based on synthetic oil. Synthetic oil should not be mixed with mineral oil.

Through-going spindle 

The spindle moves axially through the gearbox without rotation*. The nut is integrated into the gearbox.
