x translation stage: PU 90 ? adjusting range of 90µm

Product catalog summary

Overview:
The PU 40, PU 90, and PU 100 series are compact 1-axis translation stages designed for high precision and stability. These stages are made from a single metallic part with a flexure guiding system, ensuring zero friction and robustness. They support loads up to 240 N and provide motion from 40 to 100 microns. The design allows for both horizontal and vertical mounting, making them suitable for various industrial applications requiring sub-nanometer accuracy.

Specifications:

PU 40: Motion range of 40 µm in open loop, 32 µm in closed loop. Resolution of 0.08 nm in open loop, 0.8 nm in closed loop. Stiffness of 0.8 N/µm, max push force of 32 N, and pull force of 3 N.
PU 90: Motion range of 90 µm in open loop, 72 µm in closed loop. Resolution of 0.18 nm in open loop, 1.8 nm in closed loop. Stiffness of 1.5 N/µm, max push force of 135 N, and pull force of 13 N.
PU 100: Motion range of 100 µm in open loop, 80 µm in closed loop. Resolution of 0.2 nm in open loop, 2.0 nm in closed loop. Stiffness of 1.54 N/µm, max push force of 135 N, and pull force of 13 N.

Features:

High mechanical stability and stiffness.
Accurate parallel motion due to parallelogram design.
Motion without mechanical play and high resolution in nm and sub-nm range.
Integrated lever transmission and possible XY and XYZ configurations.
Precision pin holes for accurate adjustment.

Applications:
These translation stages are universally applicable for 1D, 2D, and 3D systems, particularly in mechanical engineering and precision automation.

Mounting and Accessories:
Each unit is delivered with a distance plate, precision pins, and screws for mounting. The PU series can handle tensile forces as specified for each element.

Materials and Customization:
Available in nonmagnetic stainless steel, anodized aluminum, or titanium. Options for integrated measurement systems and preparation for vacuum or cryogenic applications are available.

x translation stage: PU 90 ? adjusting range of 90µm-1

PU 40, PU 90, PU 100 series Compact 1-axis translation stages Concept: PU translators consist of a single metallic part which includes the flexure guiding system. This design means that PU translation stages show excellent mechanical stability and, because they are pre-loaded, can work dynamically. The FEA modeled flexures guarantee zero friction and high robustness. These actuators can support loads of up to 240 N in the high load version and generate single axis motion of 40 to 100 microns. They are easily adaptable because they can be mounted both horizontally and vertically. The rugged design makes the PU series well suited for all kinds of industrial applications where reliable subnanometer accuracy is needed. Specials: The elements of the PU series can be equipped with an integrated measurement system. The systems may be specially prepared for vacuum and/or cryogenic applications. Other materials, such as nonmagnetic stainless steel, anodized aluminum, or titanium, are also available. Mounting: The elements of the PU series consist of one monolithic element. Please note that there must be a space between the PU translator and the plate to which it is fixed, otherwise movement may be blocked and not parallel. To facilitate this, a distance plate is included in every delivery. Precision pin holes provide the means for very accurate mounting of the PU translators. Translators are delivered with distance plates, 2pcs precision pins, and a M4x25mm* metric screw. The PU series can be loaded with tensile forces defined by the specified pull force values for each element. * PU 40 comes with M2x12mm screw Product highlights: high mechanical stability because of high stiffness accurate parallel motion by parallelogram design motion without mechanical play high resolution in nm and sub-nm range motion up to 100 µm integrated lever transmission XY and XYZ configurations are possible precision pin holes for accurate adjustment Applications: universal application for 1D, 2D, and 3D systems mechanical engineering, precision automation
