Poly Norm
Drive Technology
KTR Poly Norm are flexible jaw couplings with flange hubs for vibration-damped torque transmission. The range comprises flange hubs in size 85 made of GGG with various bores to H7 and keyway to DIN 6885.
The design transmits torque via elastic intermediate elements while compensating for shaft misalignment. With more than 314 items, a fine gradation of bore diameters and hub versions is available.
Poly Norm jaw couplings are used in drive trains where torsional vibrations need to be damped and shaft misalignment compensated, for example with pumps, fans and generators. Selection is based on frame size, bore diameter and hub version.
