Increased reliability brought to heavy duty applications

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. The DA99 is also reliable offering an operational life up to five times longer than what a standard ball screw actuator provides.  

Known for long life, rugged construction and minimal maintenance, roller screw actuator designs are ideal for demanding applications. As such, typical uses for the DA99 include heavy presses, bending machines, injection moulding, positioning systems, machine tool axes, robotic weld guns, factory automation and discrete manufacturing applications.

The DA99 is available in 11 versions offering continuous force up to 11,800N, peak force up to 22,000N and dynamic load up to 56,000N. The DA99 offers stroke lengths from 150-300mm as standard, up to 450mm 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.

Offered in IP65 protection ratings as standard and suitable for temperatures from –15 to 40°C, the actuators can also be provided with IP66 protection and rated from temperatures from –55 to 150°C. DA99 actuators also provide high levels of shock and vibration resistance, and can be optionally supplied in explosion-proof versions.

For increased flexibility, the DA99 actuators offer a number of different mounting possibilities, including front flange, rear clevis, extended tie-rod or trunnion mounting. They are also fitted with patented lubrication ports that facilitate regular maintenance without requiring disassembly, recalibration or removal from machinery, thus reducing downtime and enhancing productivity.
