Max. perm. speed GA=1,000 rpm HA= 4,000 rpm

Precision joint extendable GA/HA

Bearing of the joint heads is made by plain bearing with precision joint type GA and by needle bearing with precision joint type HA.The plain bearings of precision joint type GA limit the maximum permissible speed to 1,000 rpm, the needle bearings of precision joint type HA limit the maximum permissible speed to 4,000 rpm. The maximum diffraction angle per joint is 45°.

Cardan shafts / precision joints in an extendable version are able to offset axial displacement in addition to angular and radial displacement.

Precision joints in various versions acc. to DIN 808

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.

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.

Extendable precision joint (cardan shaft):

  • Precision joint GA (HA): extendable precisioin joint / cardan shaft with plain bearing (GA) or needle bearing (HA).
  • Precision joint X (XD): extendable precision joint / cardan shaft with plain bearing (X) or needle bearing (XD) made of stainless steel.

Precision joint with quick lock / quick-change coupling:

  • Precision joint GR(HR): precision joint with quick lock with plain bearing (GR) or needle bearing (HR) for speed ranges of 1,000 rpm resp.  4,000 rpm.
