Screw assemblies Ball screw assemblies are the efficient solution for the precise conversion of rotary to linear motion. Building on our many years of experience and extensive engineering expertise, we have developed a product range that fulfills the most diverse requirements. No matter whether you need very high linear speeds, maximum load ratings, or minimum installed length, you will always find the right solution in Rexroth’s broad manufacturing spectrum. To make sure your application runs with the utmost accuracy and operational reliability, the individual components in our range have been...

Screw assemblies There is no self-locking effect due to the low level of friction between the screw and the nut. The components of the product are designed to last for the product's service life; a major defect may nonetheless arise in exceptional cases, and if the moving part (i.e. the screw assembly nut) is not installed horizontally it may fall off. An additional protection against falling loads is therefore required for non-horizontal installation. ► Rexroth screw assemblies are components that are used to convert a rotary motion into a linear motion, and vice versa. Rexroth screw assemblies...

Rexroth screw assemblies are suitable for dynamic linear applications that are moved and positioned reliably and precisely. The machine tool industry and other sectors must observe a series of standards and directives. These requirements can vary significantly worldwide. It is therefore essential to understand the legislation and standards that apply in DIN EN ISO 12100 This standard is entitled Safety of machinery – General principles for design – Risk assessment and risk reduction. It gives a general overview and contains a guide to the major developments governing machines and their intended...

Screw assemblies | Individual solutions Coatings - surface protection against corrosion or light reflection Aggressive media and harsh environments require robust coatings on screws and nuts - in addition, these coating could be in black to avoid reflection (e.g. of lasers). This special protective coating is particularly helpful in the optical industry, semiconductor production and aviation technology. CUSTOMIZED SCREWS AND NUTS No matter what your mechanical engineering idea requires, Bosch Rexroth manufactures customized solutions that go far beyond the standard range: ► Standard nuts with...

Individual solutions | Screw assemblies Deep hole drilling – for screws with temperature control and lubrication Bosch Rexroth also supplies hollow-drilled and rotary lead-through screws. This enables patented screw temperature control, but also lubrication of the nut via the screw if required. Temperature-controlled screws turn standard machines into precision machines with minimal effort: Without run-in times, you can reduce your reject rate as of the first part by achieving up to 75% higher part accuracy – thanks to consistent preload and rigidity. And this without additional installation...

Screw assemblies | Individual solutions Arrestor nut – for protection against Combined screws uncontrolled falling By putting different screws together, right-to-left For critical applications in non-horizontal threads, different leads, screw and shaft pieces, operation. The arrestor nut, integrated or as an etc. can be combined with each other. attachment, prevents the ball nut and the elements fastened on it from suddenly falling Special lengths can be realized without limitation off uncontrollably in the case of ball screw and, if required, also the most diverse ends can be drives installed...

Individual solutions | Screw assemblies Metal deflectors - for perfect ball return For high temperatures, in highly dynamic components or even in a vacuum, we have developed special deflectors that are used, for example, in the semiconductor industry or in glass production. Total deflection enables high load capacities by using the full nut length, quiet running and particularly uniform torque curve. Ball screw assemblies BASA ► T-slots Reworked standard and special nuts - for every special requirement In accordance with the respective environment and specific requirements, each nut from the...
