Through the use of its linear guidance systems, radial components, direct drive systems and complex bearing assemblies, The Schaeffler Group has developed system solutions for laboratory automation applications. In one recent example, a customer required a smooth running, low displacement resistance bearing solution for a new blood-testing device, with quiet operation, low maintenance and corrosion resistance being key attributes.
For the solution, Schaeffler provided a four-row linear ball bearing and guideway assembly (KUVE-B) with Corrotect coating for the X-axis, as well as corrosion-resistant miniature linear guidance systems for the Y- and Z-axes. This also had a spindle bearing with semi-locating functionality.
In another application, the customer demanded smooth running, low maintenance and low displacement resistance for its analysis device, but it also needed to have a high degree of positioning accuracy and repeatability. Here, Schaeffler developed a ready-to-fit module that consisted of four miniature linear guidance systems, two toothed racks and a mounting plate.
The company has also supplied a solution for an application that involved a DNA sequencer, where a direct-drive X-Y-Z (three-axis) unit with very high positioning accuracy and repeatability, smooth running, low displacement resistance, and maintenance-free operation was needed. The solution comprised a ready-to-fit direct drive for a mechatronics system with monorail guidance systems, miniature linear guidance systems, a PCB direct drive motor, stepper motors, encoder and housing.
Schaeffler has also developed a system solution for a laboratory sample changer which needed to be compact and robust. The solution comprised miniature linear modules, housings and motors.
