Precision joints in various versions acc. to DIN 808
Precision joints consist of a joint centerpiece and two hubs that are interlinked by straps.
The bearing of the joint heads is made by plain or needle bearing selected based on the kind of application.
This bearing allows the precision joints (single joints) to compensate for significantly larger angular displacements compared to other coupling types. Double joints that have two bearings are able to offset radial displacement in addition.
Precision joints/Cardan shafts in an extendable version are able to offset axial displacement in addition to angular and radial displacement.
Precision single joints (Cardan shaft):
* Precision joint G: standard type as single Cardan shaft / joint with plain bearings for speeds up to 1,000 rpm.
* Precision joint H: precision single Cardan shaft / joint with plain bearings for speeds up to 4,000 rpm.
Precision double joints (Cardan shaft):
* Precision joint GD: standard type as double Cardan shaft / joint with plain bearings for speeds up to 1,000 rpm.
* Precision joint HD: type as single joint / Cardan shaft with needle bearings as a precision joint for speeds from 500 to 4,000 rpm and big fleet angles.
