產(chǎn)品簡(jiǎn)介：
Double ended / unbalanced / arbitrary rotation / multi spring structure, with the same design as the "M7N" series, in addition to the installation length of the drive seat, other installation dimensions (d1< 100mm) conform to the DIN24960 standard.

Operating parameters:
d1 =18…200mm 0.625"…8"，p1=16(25)bar 230(360) PSI，t=-50…220℃ （-20…180℃*），vg=20m/s(10m/s*) 66(33)ft/s，*) d1≥105mm,
Axial thrust:d1≤100mm±0.5mm，d1>100mm±2.0mm

Stationary ring

Torque transfer

The spring is pushed into the drive pin when d1> the 100mm screws into the pit with the four screws
