Rodriguez Precision in Motion

Ballscrew 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. Features and benefits of ballscrews: - Rolled, ground and whirled ballscrews - Preload and accuracy as determined - Individual endmachining - Superfinished for highest loads - Long service life and smooth running - Fully certified and guaranteed - Systemintegration possible

Rodriguez rollerscrews are only used for transferring axial forces. They consist of a ground spindle and the threaded nut which is equipped with rollers. The special geometry of the thread and the rollers characterize the rollerscrews. The use of rollers with grooves on their outside diameter and the hereby resulting contact areas as well as the number of contact points permit a high axial load capacity. Rodriguez rollerscrews are available in two basic versions: With satellite rollers or with roller feedback. Rollerscrews with satellite-rollers or with rollercirculators consist of a ground spindle, the threaded nut and the satellite rollers. Hereby, the spindle and nut have a multiple thread profile with a slope angle of 90°. The satellite rollers are guided on both sides by geared rings and thus a distance parallel to the axis is maintained. This version of the rollerscrew is available with and without preload. To protect against coarse contaminants the threaded spindle drive nuts can be equipped with dirt wipers made of PA66. Rollerscrews with rollercirculators do not use satellite-rolelrs, but instead rollers with grooves in their outer diameter. These are spaced according to the distance of the respective pitch. For relatively high spindle diameters they offer small pitches and thus achieve a high positioning and repetition accuracy and a high efficiency.

Cross roller guides from Rodriguez are characterized by an exceptionally low-friction running, an extremely compact design and the highest degree of precision. These properties make this type of enclosed guide rail especially suited for use in the medical, biotechnology and semiconductor technology as well as in the optical industry. The cross roller guides can be installed either horizontally or vertically depending on the application. The parallel arrangement of two pairs of rails allows the guiding of a linear slide. This opens up numerous new solution possibilities. Features and benefits of the cross roller guides - Compact design - Exceptional low-friction running - High rigidity - Exceptional precision - Single and multi-configuration

In Rodriguez Linear Guideways, four rows per carriage distribute the load in four directions, and thus achieve a high rigidity. An integrated lubrication system extends maintenance intervals and makes the profile rails very low-maintenance. Optionally, these linear guides are also available with a ball chain. Upon request, Rodriguez Linear Guideways are a available with a cover made of a metal cover strip for protection against contamination. An external lubricant tank is available for the lubrication system. For particularly compact designs Rodriguez can also provide the Linear Guideways in a miniature version.

Linear roundtrails 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 roundtrails are robust, reliable, powerful and – due to their simple construction – very economical. The construction of the roundtrails, 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 roundtrails with shaft support provide an economical and robust alternative to profiled rail guides. The Rodriguez product range is therefore dimensioned accordingly: It includes: - Precision shafts made of different materials - Linear ball bushings for all performance levels - Linear slide bushings (ceramic/self lubricating) - Linear housings and components - Shaft support blocks and shaft support rails - Customer specific applications

The rugged Turntable bearings from Rodriguez are characterized by their large diameter and large bores with only a small cross-section. They were designed for axial, radial as well as combined axial and radial loads. New design concepts and improved manufacturing processes for the Turntable bearings, enable our customer's designers to implement completely new solution approaches. The bearings are very easy to assemble and demonstrate their properties particularly in small, sophisticated and high precision applications such as in the aerospace industry or in the special machinery area. The bore diameter of the Rodriguez Turntable bearings is at least 50 millimeters. The bearings are available with and without gear teeth, optionally in a corrosion-resistant or a customer specific tailor-made design. Features and benefits of the turntable bearings - Bore diameter starting from 50 mm - Simple installation - Available in various, individual versions - Available with internal or external gear and without gear - Corrosion-resistant types available on short notice - Generally short delivery times
