Selected linear axes and components from Bosch Rexroth have been tested according to the ISO 14644-1 standard and certified for the clean room classes up to ISO 3, ISO 5, and ISO 6. The certification confirms that the axes are suitable for applications with very high requirements in terms of cleanliness and process stability.
Certified clean room suitability according to ISO 14644-1 – confirmed by Fraunhofer IPA
High level of cleanliness for critical manufacturing processes
In highly sensitive manufacturing sectors, such as semiconductor or medical technology, the clean room is a key requirement for stable processes. Even microscopic particles can cause malfunctions or result in loss of quality or waste.
Bosch Rexroth offers cleanroom certified Linear Motion Technology for such challenging environments – focusing on controlled particle emissions, precision, and long service life. Depending on the application, the solutions are used as components such as ball rail systems and ball screw assemblies, as modular linear units, or as part of complex linear systems.
Validated cleanliness – certified clean room class – precise performance
The Linear Motion Technology from Bosch Rexroth has been tested by the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA) according to ISO 14644-1 and certified for clean room classes up to ISO 3.
The independent test confirms its suitability for use in clean rooms with high cleanliness requirements, such as those found in semiconductor, electronics, and medical technology. One particular component that received the certification is the new NRTVG runner block, which was developed specifically for clean room and vacuum applications and completely dispenses with plastic components. Also tested was the product range of compact modules, which is designed to minimize particle generation during operation.

FAQ
Cleanroom certified linear axes
1. According to which standard and for which clean room classes are the Bosch Rexroth linear axes certified?
2. How was the clean room suitability of the linear axes measured?
The clean room test was carried out by the Fraunhofer IPA in accordance with ISO 14644-1 under conditions close to actual operating conditions. The airborne particle emissions from the linear axes were measured in dynamic operation within a defined test setup that simulates typical industrial clean room applications. The assessment is based on the measured particle concentrations per cubic meter of air in accordance with the standard for ISO clean room classes 5 and 6.
3. What is the benefit of the Fraunhofer IPA certification for machine and plant manufacturers?
The independent testing by the Fraunhofer IPA provides machine and plant manufacturers with objective and
standard-based confirmation of clean room suitability. It reduces the validation and documentation work when designing clean room processes, increases planning reliability, and facilitates faster project implementation – particularly for applications with high requirements in terms of cleanliness, precision, and process stability.
The certified linear axes often form part of modular linear systems or linear robots. They are used in various versions, for example as linear axes with a motor, linear axes with ball screw assembly, or linear axes with toothed belt drive, depending on the application and system design.
