Space-saving design: The measuring sensor is fully integrated into the slide
Cost-effective position measurement system for a wide range of product sizes
From design to service, save time and money
Integrated absolute position measurement can be used in a wide range of applications due to its high level of EMC protection，

Bosch Rexroth has developed the new IMScompact absolute position measurement series for the IMS integrated measuring system. This non-contact solution uses the magnetic measuring principle, which allows stable and economical position measurement of linear guides of different lengths and sizes, thus replacing external linear position measurement systems. It can be applied more quickly and cost-effectively in a range of scenarios, such as effective position measurement in special mechanical structures, as well as small and large-scale applications in areas such as digital printing, battery production, and fast-moving consumer goods.
The new products complement the existing portfolio of integrated measurement systems, including the IMScompact incremental measurement system and two inductive, high-end versions for high-precision applications.
The IMScompact compact measuring system records the position of the slide without contact with an absolute accuracy of +/- 20 μm/m, a repeatability of +/- 1 μm, and a speed of up to 5 m/s. The measuring length is up to 17.8 m, and the guide consists of several segments. The sensor fully integrated into the carriage provides a high level of EMC protection, making this magnetic measuring system ideal for linear motor axes.
Available in sizes 15, 20 and 25, the IMScompact stands out from other magnetic position measurement systems due to its compact design. Even for the smallest sizes, sensors are integrated into the slider to save space. The key advantage of absolute measurement over incremental measurement is that the system can be put into use immediately after a start-up or restart in a power outage, resulting in increased productivity for many handling and automation solutions.
In new projects in the field of factory automation, the integrated measuring system has proven that it can be used to measure position in a compact and cost-effective way in linear guides, without the need for an external linear encoder. For example, it is used to measure workpieces to ensure quality or to record measurement data for further processing via the machine control system.
A second important area of application is related to linear motors, which allow high-precision positioning of objects over long travels, such as printheads in digital printers up to 5 m wide or cameras for end-of-line inspection of battery lines.
In the third application area, IMScompact has proven itself to be a cost-effective solution for the electrification of conventional hydraulic axes, e.g. in combination with electric cylinders and servo motors in all-electric press brakes.
Significant time and cost savings over the entire life cycle
The integrated IMS measuring system combines the functions of a linear guide and a linear encoder in a single system, requiring fewer components and taking up less space, thus reducing the structural design effort. The fully digital selection and configuration process as well as the online shop ordering function help to save even more time.
Thanks to the integrated electronic measuring devices, assembly and commissioning can also be completed faster. The supplied sensor and magnetic stripe are already adjusted, so there is no need to adjust the measuring head in the field. To ensure a fast time to market, IMS is available worldwide.
Thanks to the maintenance-free measuring principle, the new IMScompact also reduces operating and maintenance costs. Bosch Rexroth Service offers a quick replacement service anywhere in the world, and the rails and slides can be replaced individually. To protect the scale from contamination and damage, Bosch Rexroth also offers the option of protective belts.

Rexroth Hydraulic Pumps – Gear Pump Common Failures and Their Causes
(1) The pump does not produce oil
First of all, check whether the rotation direction of the gear pump is correct; Secondly, check whether the filter at the inlet end of the gear pump is clogged.
(2) The oil seal is flushed out
(1) The gear pump bearing is subjected to axial force;
(2) The gear pump is subjected to excessive radial force.

Rexroth hydraulic pumps - precautions for the use of hydraulic pumps
1. When the hydraulic pump is started, it should be jogged several times, and after the oil flow direction and sound are normal, it should run under low pressure for 5-10min, and then put into normal operation. Before the piston pump is started, the pump must be filled with clean working oil through the oil drain port on the casing.
2. The viscosity of the oil is affected by the temperature ...

What happens if Rexroth vane pumps are used incorrectly?
One. Wrong installation method:
1. The coupling is too tight:
Because the coupling and shaft fit clearance is too small or no backlash, the bearing will be damaged when struck hard, resulting in early bearing damage and affecting the life of the entire pump core.
2. Axial force on the shaft head:
Because...
