Carry ball screws
This document serves as the main catalogue for Eichenberger Gewinde AG, detailing their range of ball screws and lead screws. It includes specifications, applications, and ordering systems for various types of screws, such as Carry ball screws, Carry Speedline high-helix ball screws, Speedy high-helix lead screws, and Rondo round thread lead screws.
Designed for linear applications requiring heavy load transfer with high efficiency, these screws are available in diameters from 4 to 40 mm and pitches from 1 to 40 mm, suitable for high loads at medium speeds.
Characterized by a high helix for high moving speeds and efficiency, these screws come in diameters from 8 to 25 mm and pitches from 10 to 50 mm, suitable for medium loads at high speeds.
These screws offer maximum moving speeds at low rotational speeds, ideal for converting linear to rotary movements efficiently. They are available in diameters from 4 to 36 mm and pitches from 4 to 200 mm, suitable for low loads at high speeds.
An alternative to trapezoidal screws, these offer remarkable efficiency and are available in diameters from 6 to 16 mm and pitches from 2 to 5 mm, suitable for medium loads at medium speeds.
The document provides a detailed ordering system for Carry ball screws, including specifications for lead screw type, nominal size, nut type, thread direction, ball circulations, wiper options, overall length, lead accuracy, backlash, screw end machining, and assembly options.
Products adhere to ISO 9001:2008 quality management standards, ensuring high precision and reliability.
The catalogue includes detailed tables and charts for dimensions, load rates, and other technical specifications for each screw type. CAD data for the screws are available on the company's website for further technical reference.
The document lists multiple ball screw types, including 'FGI', 'FGR', 'FBI', and 'FBR', with parameters such as nominal screw diameter, outside screw diameter, core diameter, pitch, number of ball circulations, ball diameter, and standard backlash. Load ratings are provided as dynamic and static capacities.
Ball screws are available with right-hand and left-hand threads, featuring mounting threads, single-thread or tube-type ball returns, and options for wipers made of plastic, brushes, or felt rings. Lubrication holes and pin wrench holes are mentioned, though their positions are not defined.
Users are advised to consider the system's rotational speed characteristics when selecting a ball screw, as this affects the maximum rotational speed. Calculations for appropriate speed are referenced on page 39. Special designs can be requested, and all specifications are subject to change without notice.
The manufacturing process adheres to ISO 9001:2008 quality management standards.
CAD data for the ball screw types are available online at www.gewinde.ch. The document includes a legend explaining the abbreviations and symbols used in the specifications.
