Excellent metrological performance of Marposs gauges is not always sufficient to guarantee a correct measurement process: the movements executed by the gauge itself play a fundamental role within the context of the applications on grinding machines and machine tools. Marposs linear actuators are designed with this in mind, and provide outstanding positioning repeatability performance, even in the most hostile working environments.
The various different types of actuators available can be sub-divided according to type of power supply. Each model is available with a variety of different strokes, which, in some cases, may be customized according to operating requirements.
In addition to not requiring any form of hydraulic or pneumatic energy supplies, the electro-mechanically operated slides boast a large number of innovative features. They represent the ideal solution for all applications where it is not possible to use pneumatic or hydraulic systems.
External/internal diameter gauging
Length or thickness measurements
Various strokes available: 35, 50, 75, 100, 130
Option of programming intermediate steps, with speed and acceleration ramp regulation
Two operating modes: manual and automatic, for use when moving the slide during the set-up phase or under normal operating conditions (standard machine cycles)
The dimensions have been optimised depending on the stroke length in order to reduce the space taken up inside the machine to a minimum
The slides are designed for an MCBF > 1,000,000 cycles
The stainless steel body guarantees resistance in any working environment, even in the most hostile conditions. IP67 seal rating
Enables users to identify incorrect operating conditions quickly and restore the normal conditions without any unnecessary delays.
Presence of integrated micro-switches
The motor logic is capable of controlling the integrated positioning micro-switches and provide the machine with feedback

IP65 / IP67
The various different types of actuators are available in hydraulically, pneumatically and electro-magnetically operated versions.
These carriages are distinguished by the complete absence of hydraulic or pneumatic components*, and by the presence of integrated micro-switches that are controlled by the motor logic. The stainless steel body guarantees resistance in the most hostile conditions. It is possible to program operating parameters such as speed, acceleration and cycle type (manual/automatic). In the event of incorrect operating conditions, the actuator is capable of providing diagnostic information regarding the type of error that has occurred.
The slide can be controlled via machine I/O, or by the Blù system.
Hydraulically operated slides
Just like all Marposs linear actuators, these slides guarantee excellent positioning repeatability performance, together with the option of working at different pressures [8 - 30 bar].
They are available in aluminium or stainless steel versions
Due to the presence of flow regulators, they can be decelerated before entering the measurement phase in order to ensure stable positioning and reduce measurement acquisition times.
They are available in the standard version (with strokes of up to 200 mm) as well as a miniaturized version (with strokes of up to 50 mm) that was designed for measurement applications on small-scale machines.
Pneumatically operated slides
Just like all Marposs linear actuators, these slides guarantee excellent positioning repeatability performance, together with the option of working at different pressures [3 - 10 bar].
