Nook screw jacks offer the ability to lift, position, hold and support loads in a variety of industrial applications. These jacks will provide excellent performance and reliability in the average indoor industrial facility with a dry environment and an operating temperature of 32oF (0oC) – 180oF (82oC). However, not all applications are in these ideal conditions. Nook offers many options to meet non-ideal conditions.
Learn MoreRegardless of the type of worm gear jack you are considering (machine screw or ball screw), there are eight factors that are critical for developing the optimal linear motion system. In this post, we will examine these design constraints and how they can impact proper sizing, placement, and configuration of your screw jack system.
Learn MoreThere have been some interesting linear motion technical innovations designed to serve the food segment in recent years. But, many of the emerging food applications are still perfect for the venerable screw jack. It's simple yet effective design is timeless, and it is a true work horse for food applications. In the food sector, screw jack systems are typically deployed in three common and versatile arrangements. This post talks about a few of these in more detail.

Rotating Screw - R
The rotary motion of precision worm gearing (worm shaft and internally threaded worm wheel) is converted into axial linear motion of the screw, which travels through the gear box housing. The load is attached to the end of the screw.
Rotating Nut, with or without anti-rotation (axial translating Screw) - N or V?
Driven by a precision worm gearing (worm shaft and worm wheel), the rotary motion of the screw is translated into linear motion of the travelling nut on the screw.
High Speed - One full turn of the worm shaft leads to a stroke of one millimeter.
Low Speed - One full turn of the worm shaft leads to a stroke of 0.25 mm.
The stroke length of the screw jack.
Machining that is done to the end of the screw
Bellow cover for protection against external influences. Suitable for horizontal or vertical installation.
The diameter and lead of the screw used. On most units there is only one choice per size and type. On Muli 4 there are 2 different ball screw choices.
