Round single-stage lifting columns from the DD series

Powerful lifting columns are essential in ergonomic desks for providing reliable and comfortable height adjustments. OKIN's modern DD441.2 lifting columns are perfect for this task thanks to their low-backlash sliding guides. This product is an elegant drive solution for use in stable desks. The smooth profile of the DD441.2 – without any visible indentations or functional openings – can be easily integrated into a wide variety of table frame designs. This gives furniture manufacturers a great deal of freedom in the design of their desks.                                             

Proven technology with outstanding adaptability

The DD441.2's drive technology includes powerful, maintenance-free 24-volt DC motors with two Hall sensors that generate a pushing force of up to 800 N. The inner column profiles always move synchronously. Users benefit from whisper-quiet operation at all times because of the special gears. In addition, the lifting columns have an installation dimension of 650 mm and a standard-compliant stroke length of 500 mm. They provide an exceptional level of practical versatility for adjusting tables.

The DD441.2 is also compatible with OKIN’s well-established DB02 and DB03 control units, which can be programmed according to individual customer requirements. They also feature ISP intelligent system protection. The DD441.2 lifting columns are suited for constructing stable table systems according to EN 527 and BIFMA X5.5.
