  • Extensive Customization is for particular customer specifications, for instances where unique solutions are needed. 

These customization options ensure that Ewellix’s offerings are adaptable to a wide range of industrial applications,

Ewillix Linear Products

Ewellix offers ball and roller screws designed for high precision in linear motion applications. 

The roller screws from Ewellix are available in diameters ranging from 8 mm to 240 mm, with lead options from 1 mm to 50 mm. They are specifically engineered to accommodate dynamic loads up to 3,994 kN, which makes them suitable for heavy-duty applications where both high dynamics and prolonged life are crucial.

Similarly, Ewellix’s precision ball screws are available in diameters from 6 mm to 63 mm (or from 0.625 to 4 inches in imperial units), with leads ranging from 1 mm to 50 mm (or 0.1 to 0.75 inches). These ball screws can handle dynamic loads up to 3,994 kN or 84,000 lbf, ensuring high performance under substantial load and speed. This range is particularly tailored for applications that demand high-speed, accurate linear movement and are frequently utilized in high-tech environments like CNC machinery and precision assembly operations.

Linear slides are engineered to ensure precise movements with micrometer level accuracy for applications requiring detailed and controlled motion. They offer the flexibility of manual positioning, making them versatile for use in settings where automated control is not necessary. The product range includes various guide variations, featuring linear ball bearings and precision rails, which can be easily installed. These slides are suitable for all applications that demand uniform and precise sliding motion. Ewellix also provides heavy-duty linear slide rails designed to handle increased weight without compromising performance for environments where heavy loads are a factor.

Linear modules by Ewellix are used for movements with high rigidity, making them suitable for applications involving average to high loads. These modules are generally designed for easy installation and can be adapted for different industrial requirements, including those in conveyor technology and automation sectors. The design of linear modules is particularly beneficial for applications that must withstand moment loads, thanks to the robust structure of their guide systems. The availability of motorized versions enhance their functionality in more complex automation setups.
