Advantages of Fine Cyclo DA-Series

Ultra compact design

Approx. 8% smaller in diameter and >5% shorter in length and 25% high torque

Great price advantage

Use of the single-stage DA gearboxes results in significant cost advantages compared to available two-stage gearboxes of the identical torque class

Noise levels optimised and significantly reduced

Important factor when people are working near the drive applications, as for example in the medical field.

Easy installation in application

Connection geometry does not require a complex installation, nor does it require an adjustment of the drive shaft

Fully flexible design

Connection of several motor shaft diameters is possible, allowing the use of motors from many different manufacturers

Fully sealed version

Lifetime lubricated ex works
