Centrifugal testing Spin testing for research, development and production.
If rotors are subject to high centrifugal forces during operation, you must be sure that they will not permanently deform or burst. Proven methods include strength tests and durability tests at speeds above the operating speed, burst tests or the performance of service life tests using cycle tests. This gives you the certainty you need for the operation of your rotors. We carry out a variety of necessary tests on your rotating components for new and further developments or as part of quality assurance.
Your advantages with centrifugal force tests from Schenck Our service for you: Prototype testing, spin service, process optimisation
Early detection of weak points
Quality assurance
Strength test at overspeed
Service life test
Avoidance of expensive rework
Quality monitoring of production
Quality assurance for rotating components
As soon as a component is available as a prototype, its weaknesses are unknown. In our test field, we analyse rotors and assemblies and determine their behaviour in real operation. For rotors that have to withstand high centrifugal forces, we offer our service for strength and expansion tests up to 250,000 min-1, as well as burst tests for operational safety. We also carry out all necessary work on your test specimens for new and further developments or as part of quality assurance.

Innovation from Schenck - Optical strain measurement of rotors with ROSS technology
ROSS: Holistic measurement for rotor development
With its ROSS technology (Rotational Optical Strain System), Schenck RoTec enables a completely new form of strain measurement. This measures the deformation of a rotating body in the entire cross-section - during rotation. It is used, among other things, during the development and testing phase of new rotors. ROSS measures the deformation of the entire cross-section of a rotating body during rotation, not just at individual points.
Full surface analysis
ROSS technology detects cracks during testing and collects complete field data. High-resolution cameras and flash lighting capture the rotor multiple times under centrifugal force, enabling weak points to be detected at an early stage. By precisely correlating deformation with rotational speeds, ROSS simplifies design optimization. Unlike conventional methods such as strain gauges, it offers comprehensive, detailed analysis.
Reduce weight, increase performance
ROSS is ideal for the development of rotors that are subject to high centrifugal forces, such as eVTOLs, eDrives and turbine discs. It enables precise analysis of innovative materials such as carbon fibre composites and helps to reduce the amount of material and weight. In the eDrive sector, it also supports the fulfilment of requirements for accuracy, durability and cost efficiency.

Centrio
Schenck Centrio centrifugal test rigs are used to test rotating components in a centrifugal field. These are proven test rigs that are indispensable for the development, manufacture, and quality assurance of rotors in the field of green technology. The main areas of application are: material consolidation, strength testing, burst testing, LCF testing (long-term fatigue testing), and HCF testing.
The test rig contains a vacuum-tight container with integrated burst protection. This is dimensioned by Schenck to absorb the expected fragment energy when a rotor bursts.
- Maximum rotor weight: up to 6.300 kg
- Maximum rotor diameter: up to 2.700 mm
- Maximum rotor length: up to 2.250 mm
- Maximum speed: up to 250.000 rpm
Green Technology Center Support from prototype development to series production
Schenck's Green Technology Centre in Darmstadt accelerates rotor testing with centralised, modern equipment, improves product quality and shortens development times. It offers cycle and burst tests to simulate rotor behaviour over the service life and identify weak points - for targeted optimisation. As a global leader in balancing technology, Schenck RoTec supports manufacturers in rotor development, spin tests, burst analyses, process consulting and certification - especially in the context of e-mobility.
Factory balancing with Schenck
Targeted correction of imbalance during operation
With our SmartBalancer, we can balance rotors of any size and weight quickly, cost-effectively and precisely on site - without dismantling. The portable device detects the imbalance immediately and corrects it directly during operation by adding weights or removing material in one or two planes.
