Product catalog summary
Specifications:
The document details specifications for rolled ball screw sets with diameters ranging from Ø6 to Ø80 mm, quality C7, and lengths up to 3000 mm. Standard products include Ø12 to Ø40 mm with right-hand threads and double-sided flange nuts with preload P0. The material is steel 50CrMo5QT, surface hardened to 58-62HRC with a 2 mm hardening depth. Higher preloads and ground screws are available upon request.
Procedures:
Ball screw sets with preload P1 to P4 are delivered assembled, while preload P0 sets are delivered separately. End machining for bearings is available per customer drawings. Installation notes stress careful handling to prevent damage, especially for nuts with preload P0, delivered on a plastic sleeve.
Standards and Recommendations:
The document references DIN 69051 for standard flange nuts and provides guidelines for tensile/compressive loads and critical turning speeds, advising not to exceed 80% of the critical speed to avoid resonant vibrations.
Advantages:
Ball screw sets offer high efficiency due to rolling friction, suitability for high speeds, and high positioning accuracy. Lubrication is required, and there is no self-locking, necessitating brake motors for vertical installations.
Applications:
These sets are suitable for converting rotational to linear motions, precise positioning with preloads P1 to P4, and are compatible with servo and stepper motors, replacing pneumatic drives in various applications.
Key Data from Tables:
Tables provide specifications for ball screw types, including thread diameter, pitch, circuits, and load capacities. Preferred types, usually in stock, are marked in red. Calculation factors for installation situations reflect parameters like permissible axial force and critical speed.
Overview:
This document provides technical specifications for ball screw nuts, including FDU, FSC, FSE, FSK, RSK, and RSU models, detailing dimensions, load capacities, and configurations.
Specifications:
  • Ball Screw Nuts: Lists types such as FDU (double-flange nut), FSC (low-noise flange nut), FSE (high-pitch flange nut), FSK (compact flange nut), RSK (compact round nut), and RSU (single round nut).
  • Thread and Pitch: Specifies thread diameter and pitch for each model.
  • Load Capacity: Provides dynamic and static load capacities for each model.
  • Flange and Bore Details: Includes flange diameter, flange length, bore circle, and borehole diameter.
  • Preload Options: Preload levels from P0 to P4 are available, affecting stiffness and performance.
Procedures and Standards:
  • DIN 69051: The FDU model complies with DIN 69051 standards.
  • Dimensional Changes: The document reserves the right to make changes, with no liability for changes or errors.
Recommendations:
  • Preferred Types: Certain models are preferred and usually in stock, indicated in red.
  • Lubrication Holes: Some models include lubrication holes, while others like FSK and RSK do not.
Key Data from Tables:
  • Model KM-16X05-FDU-D-P0: Thread Ø 16 mm, Pitch 5 mm, Load capacity 10291 N (dynamic), 11223 N (static).
  • Model KM-32X10-FDU-D-P0: Thread Ø 32 mm, Pitch 10 mm, Load capacity 47422 N (dynamic), 76861 N (static).
  • Model KM-50X10-FDU-D-P0: Thread Ø 50 mm, Pitch 10 mm, Load capacity 58203 N (dynamic), 120791 N (static).
Conclusion:
This document serves as a comprehensive guide for selecting the appropriate ball screw nut based on load capacity, thread size, and configuration, emphasizing adherence to standards and preload options for optimal performance.

Kugelumlaufspindeln und -muttern Ball screws and ball screw nuts Eigenschaften • Wir fuhren gerollte Kugelumlauftriebe mit 06 bis 080 mm in Quali-tat C7 mit verschiedensten Steigungen als Rechts- und teilweise auch Linksgewinde in Langen bis 3000 mm • Standard sind 012 bis 040 mm, Rechtsgewinde, Muttern mit beidseiti-ger Abflachung und Vorspannung P0 • Material: Stahl 50CrMo5QT, Oberflache gehartet 58-62HRC, EHT 2 mm vom Gewindegrund • In der folgenden Ubersicht sind meist ab Lager lieferbare Vorzugstypen rot gekennzeichnet • hohere Vorspannungen, geschliffene Spindeln, runde Mutter-Flansche usw. auf Anfrage • Je hoher die Vorspannung der Mutter umso genauer ist die Positionie-rung umso geringer aber auch der Wirkungsgrad • Kugelumlauftriebe mit Vorspannungen P1 bis P4 werden nur im mon-tierten Zustand geliefert, bei Vorspannung P0 liefern wir Spindel und Mutter separat • Endenbearbeitung fur Fest- und Loslager nach Ihren Zeichnungen auf Anfrage, Beispiele siehe Seite V 061 und V 062 • bei vertikalem Einbau und gedruckten/gehobenen Lasten Spindelkni-ckung beachten • bei hohen Drehzahlen Spindeltorsion beachten Properties • We provide various rolled ball screw sets: ranging from 0 6 to 0 80 mm, in quality C7, with various pitches, as right-hand and some left-hand threads, in lengths up to 3000 mm • Standard products are 0 12 to 0 40 mm, right-hand thread, nuts with double-sided flange cut and preload of P0 • Material: steel 50CrMo5QT, surface hardened 58-62HRC, hardening depth 2 mm from thread root • In the following overview, the preferred types which are mostly available from stock are marked in red • Higher preloads, ground screws, round nut flanges, etc. are available on request • A higher preload of the nut enables a more precise positioning but leads to less efficiency • Ball screw sets with preload P1 to P4 are delivered only in their assembled state. For preload P0, we deliver the screw and nut separately. • End machining for fixed and floating bearings made according to your drawings are available on request. For examples, refer to pages V 061 and V062 • Note that screws can buckle when installed vertically and placed under pressure or lifting loads • Take the screw torsion into account when operating at high turning speeds Vorteile • Rollreibung im Gewinde, daher sehr hoher Wirkungsgrad • Geeignet fur hohe Geschwindigkeiten • Hohe Positioniergenauigkeit • Schmierung erforderlich - meist Muttern mit Schmierbohrung. • Keine Selbsthemmung! Vertikale Kugelumlauftriebe mussen mit Bremsmotoren verbaut werden Advantages • Rolling friction in the thread - thus very high efficiency • Suitable for high speeds • High positioning accuracy • Lubrication required - usually nuts with lubrication hole • No self-locking! Vertical ball screw sets must be mounted with brake motors Anwendungen • Ubertragung von rotierenden in lineare Bewegungen • Sehr exakte Positionierungen in Verbindung mit Vorspannungen P1 bis P4 • Antriebe von schnellen Lineareinheiten und Spindelhubgetrieben • Gut geeignet fur Kombination mit Servo- und Schrittmotoren • Ersatz von pneumatischen Antrieben Applications • Transmission of rotational to linear motions • Very precise positioning in conjunction with preload of P1 to P4 • Drives for fast linear units and screw jacks • Well suited for usage combined with servo and stepper motors • Replacement for pneumatic drives Montagehinweis Achtung! Kugelumlaufmuttern mit Vorspannung P0 werden auf einer Kunststoffhulse geliefert. Zur Montage die Mutter vorsichtig auf die Spindel drehen. Dabei wird die Hulse herausgeschoben. Unsachgema-l$e Montage kann zum Verlust von Kugeln und damit zur Zerstorung der Mutter fuhren. Muttern mit hoheren Vorspannungen werden montiert geliefert ^ Flanschrichtung angeben! Installation note Attention! Ball screw nuts with preload P0 are delivered on a plastic sleeve. To install, gently rotate the nut onto the screw. This will push the sleeve off. Improper installation can lead to the loss of balls and the destruction of the nut. Nuts with higher preloads are delivered already installed. ^ Please specify the flange direction!
