DA 99 Welding Actuator
Heavy-duty servo actuator for spot welding and other industrial applications
DA99 series roller screw servo actuator is a time proven solution for robotized welding guns (more than 6000 pcs in operation). A powerful 10-pole synchronuous motor, in-house designed and manufactured roller screw and special features ensure high performance, protection against water and welding sludge (IP65) and long service life.
DA99s are compatible with most of industrial robots and control systems, and can be easily installed in any type and model of welding guns. A wide range of options allow to configure the most suitable servo actuator for specific welding cell requirements.

Built-in water cooling circuit enables high performance in the most intense applications with heavy-duty welding cycles (up to 65 welds per minute with 6 kN pressure on the electrodes).
Manual drive option for the electromechanical actuator is designed to facilitate set up processes while power is off when welding gun design does not allow to extend/retract the actuator rod by its direct screwing/unscrewing (for example, when the rod is firmly attached to moveable machine mechanisms).
In this case it is possible to perform tuning of the rod position by applying a wrench towards the manual drive nut in the rear part of the actuator housing.

1.High performance & welding quality
High speed and acceleration of Diakont electric actuators allow to reduce the time of welding gun opening and closing. A specially designed 10-pole synchronous motor allows performing more welding spots without overheating compared with competitors. DA99 Diakont actuator can make 30 welds/minute at high force without need for additional cooling.
2.Robust design and reliability
The special in-house design and manufacturing of Diakont actuators and its components, from roller-screw to the housing allows to keep the quality at high level ensuring stable operation even at stressful requirements.
3.Best-in-class lifetime
Integrated and robust design of Diakont roller-screws and special know-how technologies of metal hardening provide our products with exquisite lifetime characteristics capable of bearing over 30 million weld cycles.
4.Simple maintenance
Diakont servo actuators save time on maintenance not only because of their high quality and reliability. Such a simple procedure as grease adding can also be done very easy through a zerk on the housing and requires to be done only once in 15 million cycles.
