The OPTIBELT rigid couplings which comes under the flange couplings and clamp coupling category. This flange couplings are torsionally stiff and particularly sturdy and reliable shaft connections which can withstand jolts and radially or axially acting loads. The connected shafts must be precisely aligned. The connection dimensions of the flange couplings are in accordance with DIN 116. The flange couplings form C are equipped with a hollow for axial thrust washers according to DIN 28135.

Centering of the coupling parts is achieved only by means of fitting bolts
Key slot according to DIN 6886 or DIN 6887 on request
Horizontal arrangement by form A for shaft ends with same diameters
Form B for shaft ends with different diameters
Wear and maintenance free
Maximum rotational speed is having 4000 rpm
