Products & services
Linear Technology
Linear technology from Rodriguez – precise guidance for every motion Linear guides and linear actuators are used in diverse industrial applications. Linear technology is used for example in loading and unloading processes, pick & place applications or for numerically controlled processes in machines and systems. Linear motion processes vary widely and generally require individual solutions on the basis of linear guides and linear actuators. Rodriguez offers a broad range of linear guides, profiled rail guides and linear actuators in many different sizes and types. In addition to individual custom solutions, we also develop complete linear systems with different drive variants on the basis of our linear guides.
Linear roundrails
Classic components for reliable linear motion Linear roundrails are long established as machine elements for the execution of linear motions and have optimally withstood the test of time in industrial applications. They can be used for example as adjusting units in automation tasks. Linear roundrails are robust, reliable, powerful and – due to their simple construction – very economical. The construction of the roundrails, which is based on hardened guide carriages in combination with different linear-motion bearings or linear-motion bushes, allows many possibilities for variation. Rodriguez also offers sliding bearing variants. In addition to the type of bearing, there is also a broad spectrum of guide elements to choose from. Mounting the guide shaft on different shaft supports and the use of open guide elements create additional possibilities for variations. Linear roundrails with shaft support provide an economical and robust alternative to profiled rail guides.
Linear guideways
Linear guideways - Balls on the chain Linear guideways with four rows per carriage (in X-arrangement and 45° contact angle) can handle forces from all main directions. The X-arrangement of the raceway enables easy preload installation. Moreover, the system is less sensitive for misalignment. Linear guideways of this version are usually used for adjusting and loading equipment as well as traversing units in production machines or for robot applications. An integrated lubrication system extend the service intervals and made the linear guideways extremely low-maintenance. Moreover, linear guideways of Rodriguez are available with ball cage. The carriages can also be delivered in different versions. Upon request, Rodriguez linear guideways are available with a metal cover strip for protection against contamination. An external lubricant tank is available for further extension of a maintenance interval. For particularly compact designs, Rodriguez can also provide the linear guideways in the miniature versions.
Ballscrews
For dynamic positioning applications Ballscrews and trapezoidal screw drives transform a rotational into a longitudial motion and vice versa. Rodriguez offers both types of threaded spindles in both metric and imperial dimensions and in all major industry standards. Thereby, ballscrews, which work with balls as rolling elements, offer a higher efficiency than trapezoidalscrews which is exposed to a sliding friction. Similarly, a ballscrew is preferably used for dynamic positioning applications during a continuous operation. Trapezoidalscrews on the other hand are ideal for slow movements or clamping tasks with a short duty cycle. Ballscrew with driven ballnut AMFH For conventional ballscrews speed is an obstacle for the implementation in many industrial applications. The longer the ballscrew spindle, the higher the risk will be that the required speed cannot be achieved due to the critical revolution-speed of the spindle. In these cases we recommend the use of a ballscrew with a driven ballnut. The combination of custom ballscrew nut, axial angular contact ball bearings and and a precision threaded nut will yield a powerful, toothed belt driven unit that delivers optimum results even at high speeds. Upon request, a corresponding drive wheel can also be integrated.
Value Added Products - Customized solutions
Focussed on your requirements: Customized solutions Customer requirements, technical feasibility as well as economic efficiency are the main focus of our work. Together with our customers, we are looking at their demands and implement this one in innovative ideas for current and future business areas. Thus new product visions and verified product concepts are created even before the real engineering starts. Customized solutions are one of Rodriguez core competencies. We develop, manufacture and supply complete customized solutions based on our thin section bearings and linear technology products. For these applications it is important to choose carefully the individual components and ensure their precise production and correct mounting. This is very essential for the proper functionality of customized solutions which are developed by Rodriguez. Thus you are benefitting from our entire technology- and system know-how. As a specialist for bearings we take care of every process step from the development and construction via manufacturing and mounting right up to quality inspections, field tests and setting into operations in order to provide you the best customized solution. To maintain our high standards we continuously invest in latest production technologies and in the qualification of our employees. Customers who obtain sub-assemblies or complete customized systems from Rodriguez benefit from a relief in procurement. The administrative input for the purchasing of several small components is no longer required reducing processing costs, which allow the customer to concentrate on their core competencies. This also applies especially for small quantities. The integrated functionality does include gears, grooves with control functions, mountings, brackets as well as integrated ball races at shaft or housing.
Thin-section bearings
Lightweights with a small cross-section Compact thin-section bearings by Rodriguez in inch and metric measurements are the right choice for all applications in the mechanical engineering industry, where compact design, low weight and miniaturisation is important. One of the most important applications of the Rodriguez thin-section bearings is in robotics technology. There they are used, for instance in the hand axes of painting robots in the automotive industry. With more than 250 different types of thin-section bearings up to hybrid versions with ceramic balls, Rodriguez is offering the optimal solution for each constructive problem. Smaller and lighter - this is a requirement in many modern designs. This requirement is met by thin-section bearings. Advantages of Rodriguez thin-section bearings: Thin-section bearings have a large bore diameter with a smaller bearing cross-section. Solid shafts can be replaced with hollow shafts. The free interior of the thin-section bearings can be used for air ducts, hydraulic piping, electrical wiring or slip rings. Thin-section bearings are small, light and compact. Despite miniaturisation, the performance of thin-section bearing is comparable to that of normal bearings.
