Configurable Double Tube Linear Actuators

Product catalog summary
Introduction
The document provides a comprehensive overview of configurable double tube linear actuators, focusing on their specifications, types, and ordering process. These actuators are used for precise linear movements in various applications, including machine and plant construction.
Specifications and Types
The actuators are categorized into standard (GN 4910 - GN 4960) and precision (GN 6910 - GN 6962) types. Standard actuators use trapezoidal or fine thread spindles, while precision actuators may also use recirculating ball screws for higher precision and repeatability.
Ordering Process
The process involves selecting the actuator type, configuring it with the desired accessories, and placing separate orders for the actuator and accessories. A code system is used to specify the actuator.
Technical Instructions
Technical parameters include load capacities, positioning precision, repeatability, and guidance accuracy. The document discusses backlash, self-locking properties, and lifespan considerations based on environmental conditions.
Accessories
A variety of accessories are available, such as handwheels, clamping plates, and position indicators, which enhance the functionality of the actuators.
Online Configurator
An online configurator is available for easy customization and ordering of linear actuators, providing a user-friendly interface to select designs and accessories.
Conclusion
The document emphasizes the flexibility and precision of Ganter's linear actuators, highlighting their suitability for a wide range of industrial applications. It notes that technical details are subject to change and encourages consultation with the design department for specific inquiries.
Model Highlights
1. GN 4910: Features a single slider for high torsional stiffness applications.
2. GN 4920: Includes one double slider for enhanced stability and load capacity.
3. GN 4930: Equipped with two opposing single sliders for precise linear movement.
4. GN 4940: Features two opposing double sliders for complex applications requiring synchronized movement.
Specifications
1. Materials: Guide tubes are available in chrome-plated steel or stainless steel AISI 304. End pieces and sliders are made from aluminum, available in plain or powder-coated finishes.
2. Spindle: Options include trapezoidal or fine thread spindles, made from steel or stainless steel AISI 303, with ball bearings.
3. Positioning Accuracy: ±0.2 mm per 300 mm stroke.
4. Follower Nut: Made from gun metal.
5. Screws/Nuts: Available in steel, zinc-plated, or stainless steel A2-70.
Key Considerations
When selecting a linear actuator, consider the design and length of journals, the required accessories, and the specific application needs. The document emphasizes the importance of ordering accessories separately and provides a reference to a design overview for further guidance.
Position Indicators
Position indicators GN 9534 and GN 9034 display the current position of linear actuator connectors. GN 9534 uses a mechanical counter, while GN 9034 uses an electronic display. Both types connect to the actuator via an adapter bushing and grub screw.
Handwheels
Handwheels GN 9234 are designed for linear actuators and come in disk or spoked designs. They are made from aluminum with a powder-coated finish and can be ordered with or without handles.
Clamping Plates
Clamping plates GN 9734 secure the spindles of linear actuators, preventing unintentional adjustments by clamping the spindle stem.
Torque Supports
Torque supports GN 491.2 are necessary for mounting position indicators or clamping plates on linear actuators with a nominal diameter of 18 mm.

Configurable Double Tube Linear Actuators Introduction / Overview of Types Configurable double tube linear actuators move parts along their guides. The slider moves linearly due to the lead of the spindle drive, which is located between the two round guides. A variety of kinematic designs are available to flexibly cover a wide range of application cases. Linear actuators are used anywhere that linear movements are required, such as in machine and plant construction and for format adjustment. The strokes of the double tube linear actuators can be freely selected. They can be ordered specifically...

Introduction / Overview of Types GanterNorm* Precision double tube linear actuators GN 6910 - GN 6962 Code no Slider The slider is moved along the round guides due to the spindle lead. The sliders move symmetrically along the round guides due to different lead directions. Sliding guide / rolling guide Sliding guide / rolling guide Sliding guide / rolling guide move along the round guides independently of the opposite side due to separate spindles.

Technical Instructions GanterNorm* Deflection / Elastic deformation The maximum permissible forces and torques given in the table result in elastic deformation of the linear actuator. At the indicated values, this amounts to about 0.4 mm for guide tubes and 0.3 mm for solid guide shafts. The figure shows this deformation using force Fz as an example. Positioning precision The positioning precision indicates the amount of deviation with which a specific position can be reached. The table indicates the maximum occurring deviation. Repeatability The repeatability indicates how precisely a position...

Configurable Double Tube Linear Actuators-8

Configurable Double Tube Linear Actuators Technical Instructions Self-locking Since the lead angle of trapezoidal and fine thread spindles is smaller than the angle of friction, these spindles are selflocking. It is not possible to push the linear actuator. The spindle can also be additionally secured with an external spindle lock by means of clamping plates. Due to its lower rolling friction, the ball screw drive has no self-locking properties. Lifespan The lifespan of linear actuators in a given application depends on the expected environmental conditions. The following factors come into play:...
