Frequently Asked Questions

RD Motion seeks to provide a wide range of B2B services aimed specifically at supporting our customers in their R&D efforts. We strive for maximum agility and adaptability in order to always fulfill our customer's needs, which requires constant upgrades to our portfolio of provided solutions. Below are some of the most common questions we get asked, which will hopefully help you better understand what our company is all about.

  • What range of products and services does the company RD Motion provide?

    RD Motion is committed to providing a wide variety of products and services for material testing and data acquisition, specifically related to the field of power transmissions. Our flagship product is a multifunctional testing system, which enables polymer and composite gear tests, tribological twin-disc tests, along with testing of rotary seals. The testing system enables the acquisition of all data necessary for the development of highly optimized polymer power transmissions.

  • Is it also possible to order material testing as a service?

    Testing as a service is of course possible. We have specialized internal test rigs for testing of polymer gears and tribological twin-disc tests. On our internally available test rigs we can perform gear and tribological tests in a variety of different load and thermal conditions. Samples can either be supplied by the customer or prepared by us. All you need to do is to determine the test conditions and the information you need to gain from the test. With our wide experience in developing high-performance power transmission applications, we can also help you determine which information is really essential for the design process of your product. We additionally cover a wide range of standard mechanical tests.

  • What type of tests will I be able to order and how will I be able to access the result data?

    RD Motion offers testing as a service on our internal testing systems. The types of tests which we can offer include but are not limited to:

    • Polymer gear testing: temperature-dependent fatigue curves, wear, contact fatigue, efficiency tests and coefficient of friciton evaluation
    • Tribological tests: twin-disk, pin-on-disk,…
    • Standard mechanical tests: tensile/flexural strength, hardness, fracture toughness, impact testing, creep, DMA, non-destructive testing, etc.
    • Thermal testing: hot disk, DSC
    • Test sample analysis under digital microscope and scanning electron microscope (SEM)
    The test data will be delivered to you in a pre-determined form (raw data, processed data).

  • Does your company also provide custom testing system development solutions?

    Yes we offer also custom testing system development. We are specialized in the field of power transmission therefore our typical developed solutions include rigs for testing of gears, electric motors, clutches, belts, chains and bearings. However we can relate also to other engineering problems. Our engineers have more than 15 years of combined experience and top-knotch know-how in developing different testing systems as also other industrial applications therefore we are able to address the most difficult problems.

  • What about custom R&D services?

    We can offer support in you R&D process and supplement your team with additional knowledge and experience or we can take over the whole project and develop the required product from the initial idea up to final technical drawings necessary for the final production.
