Product Overview

Definition of Precision Ball Screw AssemblyDIN 69 051, Part 1 defines a ball screw as follows: An assembly comprising a ball screw shaft and a ball nut and which is capable of converting rotary motion into linear motion and vice versa. The rolling elements of the assembly are balls. As simple as it is to describe the elementary function of a precision ball screw assembly, in practice you are faced with a variety of types and applications. A new nut series, new sizes in right-hand and left-hand versions, as well as a new nut housing as an accessory have increased the scope of the catalog still further. Rexroth Precision Ball Screw Assemblies provide technical designers with diverse solutions for positioning and transport tasks with driven screws or also with driven nuts. With Rexroth, you can be sure of finding products tailored to special applications and uses. Here are some examples: ECO series: the low-cost solution through to the medium size range in the form of screw-in nut or single nut with flange Speed series: maximum linear speeds with simultaneous high load rating and short nut length The latest 2008 additions to the product range: 2-start single nut with flange FED-E-B, provides a distinct increase in the dynamic and static load ratings as a result of two separate ball tracks. Single nut with flange, FEM-E-S, left-hand version in several sizes; also available in the size 20x10R Nut housing MAG-Z for the cylindrical nut The nuts with flanges from the Standard series are available in versions with either Rexroth or DIN mounting dimensions. The related standards (DIN 69 051 and ISO 3408) are therefore fully supported by Rexroth. In order to make it easier for customers to decide between particular series and/or sizes in terms of delivery time as well, we have introduced A, B and C categories for nuts. Each individual ball nut part number is assigned to a particular category. Category A parts are always stocked in the quantities of average demand. Certain stocks of Category B parts are also kept, but customers should inquire about the availability of these parts. Category C parts are exclusively made to order. Almost all single nuts in the version with backlash can be easily mounted on the screw by the customer, especially during servicing. In addition, the adjustablepreload single nut of the Standard series allows the customer to perform preload adjustment in-house. Matching nut housings for the Standard series and several types of end bearings are also stocked.

Precision-rolled screwsPrecision-rolled screws in a variety of sizes and of unequaled quality have long been an essential part of our product range. Our comprehensive, worldwide stocks guarantee fast response times in every location. Availability is one advantage, low prices another. Every nut featured in this catalog can be combined with the precision-rolled screws. Precision-rolled screws can also be supplied without ball nuts to allow customers to machine the screw ends on their own facilities. Since hard machining has meantime become an established method, we no longer anneal the screw ends, a process which was previously necessary but which lowers the quality of the material. For special servicing cases, please consult us.

WINKGT calculation softwareThe WINKGT calculation software for designing and calculating precision ball screw assemblies for the operating system Windows 95 through XP is available on CD-ROM. This makes it very easy for you to perform your own technical calculations. Alternatively, you can arrange for Rexroth to produce a technical design calculation on your behalf by completing and returning the Design Calculation Service Form at the end of the catalog. For the simplified creation of drawings of our precision ball screw assemblies as a CAD file, see the section headed Inquiries and Orders and the Inquiry/ Order form at the end of the catalog.

Product Overview

Precision Ball Screw Assemblies for All ApplicationsDrive unitsYou will find further system solutions in our catalog on Rexroth Drive Units. This catalog contains precision ball screw assemblies with a protecting housing, including versions with integrated screw supports, driven nuts with side drive timing belt and the matching AC servo motors.

To perform particularly demanding positioning tasks we have developed the Integrated Measuring System for Ball Rail and Roller Rail Systems (Catalog R310EN 2350). The linear measuring system in the rail then replaces the positioning information in the ball screw. This way we are able to achieve a maximum of flexibility in design and a maximum of precision in operation.

Inquiries and Orders

Inquiries and OrdersAll nuts, screws and end machining details can now be defined with the order code (up to screw diameter 80 mm) as a complete precision ball screw assembly. We have taken account of all former selection criteria as well as adding new ones. The diversity of possible combinations is limitless. Attention is focused in particular on the definition of end machining details. For many design versions there is a prepared definition, providing you with a suitable solution for practically every application. If you wish to send us an inquiry, simply complete the form at the end of this catalog. If no drawing is available, please specify your wishes using the variable order code. You will find a summary of the options on page 19. Should you already have a drawing available as a CAD file in Pro/E, AutoCAD, STEP or DXF, you can send us the data by e-mail to [email protected]. If the drawing exists on paper only, you can, of course, send it to us by conventional mail. Each customer-specific precision ball screw assembly is issued with an ID number when an order is placed. If you have any subsequent queries, you need only quote this ID number. Using the ordering data from the cata-log, you can also easily generate a drawing in AutoCAD format via the functionality provided on our website. A guided dialogue is provided for data input so as to avoid typing errors, and all data selected can be checked within a few minutes against the drawing that has been generated. This drawing can then be used directly by our production departments, which accelerates order processing and delivery. The drawing generation functionality can be used without registering with us or entering a password or customer number. To access this functionality, visit http:// www.boschrexroth.com/ball_screws. From there, you can access the on-line catalog via the link CAD files: Select individual types in the right navigation bar. The menu Ball screw assemblies on the left brings you to the desired goal. Data can be input in two ways. In the default mode, Configuration of options, the dialog is supported by meaningful default settings to minimize input errors. The Expert configuration mode allows much more rapid input of data, but requires a certain amount of experience. When the dialogue is completed, a click on the CAD-Model button leads to a further dialog box asking for input of the e-mail address for electronic transmission of the drawing to the user. Registered customers based in Germany can use further eShop functions such as the shopping cart, the inquiry list and order status and can receive direct offers for the inquired precision ball screw assemblies or check the delivery status of current orders.

Nut Housings

Nut Housing MGSSteel nut housings MGS are designed for FEM-E-S, FDM-E-S, FEP-E-S and SEM-E-S ball nuts. In addition to bolting, the housings should be locked in place by positive means (e.g. two pins with a diameter equal to that of the screws S2). We recommend using screws with a strength class of 8.8. Tightening torque see Mounting Reference edges are formed on both sides.

Precision-rolled screws SN-R, with mechanically connected screw endsThese screws consist of a precision-rolled screw part and an unmachined spigot. The spigot is mechanically connected on one side and is available in different sizes. We have a solution to prevent problems arising from big end bearing diameters (e.g. visible thread grooves or axial contact faces which are too small for the fixed bearing). Please ask. Separate delivery of a screw without end machining and without nut is not planned.Size d0 x P x DW 6 x 1R x 0.8 6 x 2R x 0.8 8 x 1R x 0.8 8 x 2R x 1.2 8 x 2.5R x 1.588 12 x 2R x 1.2 12 x 5R x 2 12 x 10R x 2 16 x 5R x 3 16 x 10R x 3 16 x 16R x 3 20 x 5R x 3 20 x 20R x 3.5 25 x 5R x 3 25 x 10R x 3 25 x 25R x 3.5 32 x 5R x 3.5 32 x 10R x 3.969 32 x 20R x 3.969 32 x 32R x 3.969 40 x 10R x 6 40 x 20R x 6 50 x 10R x 6 50 x 20R x 6.5
