Inmoco has recently introduced the DA99 linear roller screw actuators from Diakont, for transferring proven technology from the nuclear industry to meet other highly demanding applications. Leveraging Diakont’s roller screw designs that are utilised by nuclear power plants worldwide, the DA99 actuators deliver increased load capacity in a more compact package, and combine this with greater reliability and longer operational lifetimes compared to other designs.
The DA99 combines an integrated permanent magnet synchronous motor (PMSM) for a compact design and employs a roller screw system for converting rotary torque to linear motion instead of a typical ball screw mechanism, providing increased rigidity and greater load carrying capacity. Reliability is also improved with the DA99 offering an operational life of up to five times longer than a standard ball screw actuator.
The DA99 is available in 11 versions offering continuous force up to 11,800 N, peak force up to 22,000 N and dynamic load up to 56,000 N. The DA99 offers stroke lengths from 150 mm to 300 mm as standard, up to 450 mm on request, and with diameters of less than 100 mm, DA99 actuators are highly compact for ease of integration into applications where available space is limited.
DA99 actuators are constructed from ruggedised components to deliver increased reliability in harsh environmental conditions. For increased flexibility, the DA99 actuators offer a number of different mounting possibilities, including front flange, rear clevis, extended tie-rod or trunnion mounting.
