Applications :

Rolling element linear motion bearings are widely used to guide, support, locate, and accurately move  machinery components and products in a wide range of automation applications. Rolling element  linear bearings and guides provide low friction, smooth, accurate motion for nearly any moment or  normal loading condition. Major applications include factory automation, medical, packaging,  machine tool, semiconductor, printing, automotive assembly, aerospace and food processing.   Specifying the right bearing for a given application is necessary to save time and excessive costs.  Understanding the tradeoffs of each bearing type is important to accurately size and select the right  bearing for your application. Choosing an inadequate solution can lead to higher costs in design,  surface preparation, materials, assembly, and bearing maintenance. Or worse, it can lead to  insufficient machine accuracy, repeatability, and life, requiring an entirely new type of linear guide.  

• The bearings can support high loads while having a relatively,low mass and allow the construction of linear guidance systems with unlimited trave
• Operating Temperatures:–20 °C to +100 °C (with brief peaks up to +100 °C)
•  Linear ball bearings are available in open and closed variants
• suitable for specialized mass production, quality, reliability, producing a high efficiency, low cost;
• The bearings can support high loads while having a relativelylow mass and allow the construction of linear guidance systemswith unlimited travel
• For applications where inexact substructures could lead to preload variations
