Slide screw drives
High precision with maximum flexibility
Feinmess Suhl GmbH – a company in the Steinmeyer Group – offers slide screw drives for high-precision positioning in precision mechanical assemblies. The manufacturer has now expanded its range to include a new product series – the FLEX drive. The innovative solution compensates for inaccuracies in the system, optimizes the running behavior of the spindle and significantly reduces assembly effort.
Slide screw drives tend to experience a significant deterioration in their running behavior even with a minimal angular misalignment of 100 µRad or a parallel offset of the nut and slide. This can lead to stiffness, increased wear and ultimately to the failure of the tribological system. Therefore, the highest level of accuracy must be ensured when installing a slide screw drive in an assembly.
With the new Flex drive, Feinmess Suhl GmbH reconciles the industry's high demands for precision and simplicity. "The solution is extremely simple - by encapsulating the nut and attaching compensation elements, possible misalignments or parallel offsets are neutralized, so that a very high level of accuracy can be achieved when assembling the nut without great effort," explains René Schiffmann, Head of Sales at Feinmess Suhl GmbH. The backlash-free preloaded nut has four solid-body joints that prevent tilting in two planes and parallel offset in two orthogonal directions to the direction of travel, and thus force on the nut. In addition, a lubricant reservoir can be inserted to ensure that the slide screw drive functions perfectly over a long period of time.
Designs according to customer requirements
The manufacturer is currently offering its new product line for high-precision applications with a hardened and ground spindle, a metric ISO thread with a flank angle of 60° or a trapezoidal thread, with up to four threads and various bearing designs. The spindle is available with a nominal diameter between 3 mm and 12 mm, a pitch of 0.2 mm to 5 mm and a length of 70 mm to 310 mm. "The customers provide us with the framework for the design of the FLEX drive in their inquiry - we then adapt the product accordingly," Schiffmann continues. Thanks to years of experience in the production of slide screw drives, the manufacturer is able to respond precisely to individual requirements. The OEM market benefits from the outstanding accuracy of the spindle drives in installation situations that would otherwise have required high-precision attachments, very experienced fitters and a complex adjustment process.
More than 100 years of experience in the production of slide screw drives make Feinmess Suhl GmbH a strong partner. As a member of the Steinmeyer Group, the company also supplies entire assemblies if required - including motor and drive electronics if required, so that the customer does not have to carry out any assembly work.
