• Lifetime lubrication via additional seals offering protection against contamination
• Compact, easy to use and straightforward integration with a rotating nut

Features:

• Standard protection wipers at each nut end and optional double protection
• High rotational speed up to nd0 = 90 000, resulting in high linear speed up to 110 m/min
• Nut design well suited for transport or positioning screw applications requiring high velocity such as woodworking, some functions in plastic injection presses, pick and place etc.
• Compact, easy and simple solution to incorporate into application (SLT)

The Ewellix range of large pitch ball screws has been specially developed by Ewellix for fast linear speeds to increase productivity and represent a winning combination of precision roller technology and end cap return. This design is suitable for most positioning applications thanks to the precision ground outer surface of the nut and flange support. The products in this series are designed by Ewellix to provide even greater positioning accuracy, as well as slip prevention.
Additionally, Ewellix also offers various types of threaded nuts to minimise the mass inertia torque for high pitch spindles. The spindle is rigidly fixed to the machine frame, while the ball screw nut rotating in a bearing housing is driven by a traction belt and moves along the spindle.
Ewellix also offers a range of rotating nut solutions to minimize the inertia phenomenon associated with long rotating shafts. The long lead screw shaft is rigidly fixed to the machine frame while the ball nut, rotating inside a bearing housing and driven via a tension belt, moves along the screw shaft.

Benefits:

• Ready-to-use complete bearing unit, simplified design, easier ordering procedure
• Quick assembly onto the shaft and elimination of the majority of technical problems
• Simplified process for choosing customised solutions thanks to the combined load carrying capacity of the bearing and roller screw
• Rigid and precise positioning of the roller screw with lubricated and maintenance-free solution

Features:

• SKF preloaded angular contact ball bearings, 72 or 73 series, in back-to-back arrangement (1+1 for smaller sizes, and 2+2 for bigger sizes)
• Bearing load carrying capacity matched to the roller screw load carrying capacity
• Bearing assembled with preload providing stiff and accurate roller screw positioning
• Greased for life / maintenance-free

Ewellix offers a full range of support bearings to be fitted on the machined ends of the planetary and recirculating roller screws. These support bearings incorporate high-performance ball bearings, plus efficient sealing solutions providing a long service life to the complete roller screw assembly.

Benefits:

• Smooth running with low noise levels
• High speed capabilities, up to 2.4 times the standard range
• Provides long service life and excellent repeatability
• High positioning accuracy

Features:

• New recirculation technology and new thread profile definition
• Interchangeable with most existing standard solutions
• Lubrication hole and wiper housings standard
• Customised axial play and backlash elimination available

Ewellix's high-performance miniature ball screws offer device manufacturers new design and performance options with high reliability, precision and repeatability, and low noise levels.
It allows designers to reduce machine size, improve reliability, increase speed and power, and reduce operating noise for a wide variety of applications.
Our miniature ball screws enable precise and quiet positioning at high speed and low friction and require minimal maintenance. They are designed for high axial loads and are available in a wide range of robust, custom designs to suit practically all applications.
Enabling precise positioning for miniature applications, these quiet-running miniature ball screws operate at high speeds with low friction and minimal service requirements. Robust and capable of handling high thrust loads, the screws are supplied in a wide range of types and available as customized solutions to meet virtually any application requirement.

Benefits:

Universal ball screws from Ewellix are based on precision roller technology and represent compact, highly efficient drive solutions.
The nut can be equipped with a threaded tip or a flange (either cylindrical or in accordance with DIN 69051) for easy installation.
Depending on the application, special flanges can optionally be attached to the threaded tip of the nut. If required, customer-specific solutions are also available.
This design is suitable for most positioning applications thanks to the precision ground outer surface of the nut, flange support and nut thread. The range is offered by Ewellix with anti-slip or preloaded products for even greater positioning accuracy.
This extremely high-quality ball screw series is a competitive alternative to ground ball screws. In addition, it is a cost-effective replacement for DIN nut versions in most applications.
