Precision joints GR/HR

Precision single joints:- Precision joint G: standard type with plain bearings for speeds up to 1,000 rpm.- Precision joint H: precision single cardan shaft with plain bearings for speeds up to 4,000 rpm.Precision double joints:- Precision joint GD: standard type with plain bearings for speeds up to 1,000 rpm.- Precision joint HD: type as single joint with needle bearings as a precision joint for speeds from 500 to 4,000 rpm and big fleet angles.Extendable precision joint:- Precision joint GA (HA): with plain bearing (GA) or needle bearing (HA).- Precision joint X (XD): with plain bearing (X) or needle bearing (XD) made of stainless steel.Precision joint with quick lock / quick-change coupling:- Precision joint GR(HR): quick lock with plain bearing (GR) or needle bearing (HR) for speed ranges of 1,000 rpm resp. 4,000 rpm.

Precision joints consist of a joint centre piece and two hubs that are interlinked by straps. 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.
